Research on performance test analysis method of mechanical structure based on measured error / virtual simulation

Mechanical errors seriously affect the transmission performance of mechanical structure, especially for high-precision structure. With development virtual simulation technology, test structure in environment is gradually applied. Under background, this paper takes movable tooth reducer as research object and puts forward a method by combing with technology. The profile key components are obtained optical scanning, carried out. Meanwhile, accuracy verified implementation vibration test. results show that both simulated acceleration experimental double-peak variation trend, frequency difference between two peaks less than 5%. Therefore, proposed can effectively evaluate structures.
