Technical indicators: 1 The testing machine is mainly composed of
host, parameter measurement display unit, strong current control unit, test appendix, etc.
2 The main engine is made of casting structure, the specimen is easy to install, the wheel does not rotate, and the load rotation 3 The applied torque is measured through the relationship between load and speed, which can greatly save the test energy consumption
.
4 The driving power adopts a variable frequency speed regulation motor to achieve stepless speed regulation, thereby driving the load to rotate at high speed and exerting a bending moment
on the wheel on the rotating shaft.
5 During the test, the bending of the spindle during the test process is detected, so as to realize the emergency stop function
of wheel destruction.
6 The measurement control software has the following main functions; 7 Test parameters are set by software; 8 software display test graphics, loading force values, etc.
