Fatigue of LPQW-50000 Wheel in Rotation and Bending testing machine

This testing machine is driven by variable frequency motor to apply bending moment to the wheel by centrifugal loading, so as to test the bending fatigue resistance of the wheel. It is mainly used for the wheel rotation and bending fatigue testing machine of trucks and heavy trucks.
1. The testing machine is mainly composed of main engine, parameter measurement display unit, high-voltage control unit and test accessories.
The main engine is made of square box structure, which is convenient for sample installation, the wheel does not rotate and the load rotates;
Frequency conversion motor is used as the driving power to realize stepless speed regulation, thus driving the load to rotate at high speed and exerting bending moment on the wheel on the rotating shaft;
4. The loading wheel is installed through the cylinder at the bottom and the positioning and clamping mechanism;
5. The bending moment of the wheel is loaded by the centrifugal force of the high-speed rotation of the weight, and the bending moment is adjusted by changing the weights with different weights and adjusting the rotating speed;
6. Equipped with high-precision non-contact laser sensor to measure and detect the wheel deformation; During the test, the bending of the spindle during the test is detected, so as to realize the emergency stop function of wheel damage;
7 Measurement control software has the following main functions;
7.1 Test parameters are set by software;
7.2 The software displays test graphs, loading force values, etc. Report printing; Document management;
7.3 Closed-loop adjustment of bending moment, showing the resonance circle of bending moment and displacement, load curve and displacement curve on the screen X-Y coordinate system;
