Operating modes
The materials testing machine can only be operated via a PC with the corresponding program.
Information on preparation of test tools can be obtained from chapter Retrofit, section Specimen grips.
A word about temperature The testControl electronics is a high quality measuring electronics. To enable the electronics to work to its utmost capabilities, you must 1. Keep to the warm-up time of approx. one hour for the electronics 2. Ensure a constant ambient and test temperature.
Why? Tests to standards require constant temperatures for both the electronics and for the vicinity. Only in this way can relevant statements on your specimen be made.
Topic 1. The internal temperature of the testControl electronics stabilizes after approx. one hour.
Topic 2. The testControl electronics will inform you if it has detected ambient temperature deviations that happen to be too high. Tests will not be cancelled.

Operating notes
The following procedure is practical for daily use:
01. Switch the machine on via the main switch on the testControl electronics below the machine tabletop.
02. Switch on and boot the PC. Start the testXpert® software and UBM500.ZPV.
03. Open the safety cover. If necessary, first unlock it via the software using the „Safety door“ button.
04. Select a suitable collet chuck for the specimen diameter.
05. Slide specimen into the collet chuck. Only specimens as per DIN 50113 are permissible
06. Insert the supplied metal rod into the handwheel and use it to tighten both collet chucks while countering with the hook spanner.
07. Close the safety cover.
08. Set approx. 100...200 mbar with the pressure control valve of the pneumatic supply unit, so that the load bearing floats on the
air cushion.
09. Produce air cushions by opening the ON/OFF valve. If vibrations occur, reduce the air pressure by turning the valve.
09. The load application weight m required for a certain flexural stress sB (sigma) is calculated according to the following formula:
For notched specimens, the resisting moment of the core or remaining cross section is used (according to DIN 50113).
Further specimens can be found in testXpert under Help testXpert® Info about rotating bar bending fatigue test.

Bending moment result module:
The bending moment is calculated from the load application mass, the gravitational acceleration and the lever length. On the rotating bend fatigue test system UBM200, this lever is 1 m long.
M = m x g x l
M: Bending moment in Nm m: Load application mass in kg g: Gravitational acceleration in m/s² l: Lever length in m
M is calculated from the effective force at the start of test and the lever length of 1 m if a load cell is connected.
Resisting moment:
For a solid shaft (un-notched specimen)
W = π x d3 / 32
M: Bending moment in Nm d: Diameter of the specimen
Static flexural stress result module:
The static flexural stress is calculated as follows:
s (sigma) = M / W
s (sigma): Static flexural stress M: Bending moment in Nm W: Resisting moment
The load application mass is calculated as follows:
l x g m =
s (sigma) x W

10. Tare the load application weight (steel balls measuring around 3 - 5 mm in diameter (ball bearings) have proven to be useful for
this purpose). Standard weights are also available as an option.
The load application weight can be tared either via an external scale or using the load cell option.
The user can now proceed as follows, via the testXpert® application button „Load application mass“:
a) Zero the force using the corresponding icon on the tool bar
b) Hang in the bucket
c) Fill in steel balls until the determined load application weight is reached. The force can be read off in N or in kg on the running display.
d) The load application weight is adopted as the load application mass parameter using the Flexural load button.
e) Hang in the bucket on the load unit again.
The further parameter assignment of the test sequence, e.g. the specimen data, test r.p.m., limit cycle and break detection parameters, etc., is performed via the testXpert® software.

Specimen preparation
The cylindrical shafts must be at least 45 mm long and must have a diameter tolerance class of h9. The specimens must be produced according to DIN 50113. True running must be better than 2/100 mm.
Fault rectification
If the machine cannot be switched on using the „ON“ button on the testControl unit, this may be caused by the following:
a) The main switch is off or the mains plug is unplugged: Establish connection with the mains.
b) The EMERGENCY STOP button is actuated or activated. Pull the EMERGENCY STOP button out again.
c) Fuses tripped in the testControl electronics. Please contact the Zwick hotline (see chapter 15 in this manual
for contact information)
d) Machine has mechanically blocked: Manually check the machine for smooth operation. If necessary, remedy
the blockage while observing the applicable safety notes.
If the machine produces unusual noises, either true running of the clamped specimens is inadequate or one of the
rolling-contact bearings is faulty. Please contact the Zwick hotline (see chapter 15 of this manual
for contact information).
e) Safety cover not closed properly.

Load bearing with air cushion
INSTRUCTIONS FOR HANDLING THE AIR CUSHION PNEUMATICS
The load bearing and the load lever are supported by four air cushions. Two each of the four air chambers are interconnected by bores in the plate. The throttle valve reduces the air pressure on the side facing away from the load lever until the weight asymmetry is compensated.
Procedure
1. The guide rail for the break limit switch is lowered parallel until the roller on the end of the load lever no longer touches this rail (around 2- 3 mm clearance).
2. After connection to the usual laboratory or workshop compressed air supply, the cut-off valve is opened.
3. Approx. 100...200 mbar is set with the air pressure control valve.
4. The throttle valve is set so that the weight asymmetry produced by the load lever is compensated. This can be easily checked by pushing the load lever slightly.
5. Using the same checking method, the pressure is reduced with the air pressure control valve until the load bearing can still just slide freely.
6. This free sliding state can now be used to facilitate specimen gripping.
7. After gripping the specimen, check true running by turning manually. The compressed air is then switched off briefly by closing of the cut-off valve while the machine is accelerating. The compressed air is switched on again once the desired speed has been reached. This method offers the advantage of damping the vibrations when passing through any resonant speeds.

8. If readily perceptible vibrations should occur at operating speedafter the air cushions are switched on again, they can be damped by reducing the air cushion pressure. A slight residual vibration should still be perceptible, so that the vibration-compensating effect of friction does not begin to falsify the load. If the damping effect of reducing the air pressure is inadequate, the limit-switch rail can be additionally raised again.

Operational controls Drive/electronics
Operational controls
The materials testing machine is controlled and monitored via a PC and a modern, convenient program system. This reduces the operational controls on the machine itself to a minimum.
EMERGENCY STOP
In the event of danger, you can stop the machine movement immediately by hitting or pressing the <EMERGENCY STOP> button. The drive motor is thus disconnected from the power supply, and is eventually stopped via a brake resistor.
The <EMERGENCY STOP> button remains in the „Off“ position once it has been activated. Turn the <EMERGENCY STOP> button to release it. The <EMERGENCY STOP> button then goes into the released position.
The drive remains at zero potential even after you have ‘reactivated’ the <EMERGENCY STOP> button. You must press the <ON> button.
Main switch unit
The main switch is to be found at the side of or behind the materials testing machine’s measurement and control electronics console. Switch on the materials testing machine. A ‘1’ can be seen in the switch’s view window when the machine is switched on.

Temperature
The electronics constitute a high-quality measuring system. To enable the electronics to work to their utmost capability, you must
- Adhere to the warm-up time of approx. one hour for the electronics
- Ensure a constant ambient and test temperature.
Why? Tests to standards require constant temperatures for both the electronics and for the vicinity. Only in this way can relevant statements on your specimen be made.
Stable ambient and test temperatures The electronics will inform you of excessive deviations in ambient temperature. Tests will not be cancelled.
Heating up time The internal temperature of the electronics stabilizes after approx. one hour.

Safety cover
The safety cover is interlocked automatically at a certain minimum speed or at the start of the test. The cover can be opened only when the speed is below the minimum speed.
Danger of injury through rotating parts.
The emergency stop circuit is always switched off when the safety cover is opened, thus reliably preventing the motor from turning. When the safety cover is closed again, the ON button must be confirmed again on testControl.
Caution: parts continue to coast after the safety cover is opened. Do not perform any work in the test area until the drive, motor and clamping device have come to a complete stop.
A triangle socket key is supplied for the key-operated switch for emergency release of the safety cover. The mechanical interlock must always be in the „interlocked“ position for normal operation.
The key must be kept by the safety officer.
Temperature
Danger of burns. The motor, the specimen and the specimen grips can become very hot over an extended test duration. Never ever leave hot specimens lying around unprotected. Only work with heat-resistant protective gloves.
Laser pointer/temperature measuring device
Safety goggles aren’t necessary. However, avoid looking at the laser light directly or with the aid of optical instruments.
Work on the laser must must be performed by trained service personnel only.

General description
Machine’s setup
A lead screw supported by a fixed bearing is located on the right side of the machine bed. This lead screw is driven by an electric motor behind it. Opposite the lead screw on the left side, the load bearing that introduces the bending moment into the specimen via a non-driven shaft can move freely on a horizontal sliding surface. The specimen shafts are positively connected with the lead screw or the shaft of the load bearing with the aid of standard collet chucks. The bending moment is produced by a larger or smaller weight according to the magnitude of the bending moment. This weight acts on a 1,000-mm-long horizonal lever arm via a cable and a deflection roller. The absolute value of the max. tensile or compressive stress arising in the edge fiber results from the following relationship for unnotched, rotationally symmetrical specimens:
MB m · 9.81 · 1,000 · 32 N s (sigma) = —— = ——————————————
W d3 · P (Pi) mm²
Whereby: MB = Bending moment W = Resisting moment of the specimen m = Load application weight (kg) d = Specimen diameter (mm) in the test cross-section
The force acting on the lever arm produces an axial load stress in the specimen, but this stress is less than 0.2% of the flexural stress in the edge fiber and is thus negligible.
General description
The rotating bend fatigue test system produces a sinusoidal load characteristic by superimposing a free bending moment on the specimen rotation. The absolute value of the upper and lower stresses is identical, but the mathematical sign differs. The bending moment is constant over the entire specimen length because four-point bending is used. The max. permissible bending moment is 200 Nm.
