Fault Simulation of Tanks Sight Based on Optical Parts Fretting

Aiming at the problem of maintenance and it is difficult to find the fault caused by optical parts fretting. By means of mathematical tools to express optical parts imaging laws. With the computer simulation technology, combining with optical fretting theory and practical problems, producting a set of simulation software and showing the influence of optical parts fretting. The results show that the fretting of optical elements influence the imaging effect and firing accuracy. For the maintenance training of universal and serialized sighting telescope, the simulation research provides technical means.
