Simulation Analysis of Mechanical Reverse Fatigue Tests Device

The author has designed a low-cost mechanical test device for checking reverse fatigue life of auto driveshaft on a certain torque.In order to test the device performance,the author who used Multi-body dynamics software ADAMS set up the test device dynamical model,and do simulation analysis on each state's movement,gained the reverse angle curve and other data which the test device can achieve on different parameters.The article also analysis of the causes and solutions of waveform distortion during the testing,for further improve the design and improvement of test,steering test is of great significance.
