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.

Aiming at the present application of fault simulation technology based on virtual prototype, virtual prototype technology and fault injection technology were studied and analyzed, and the fault injection technology was improved. Taking a mechanical system as research subject, the mechanism of fault caused by a spring's fatigue failure was analyzed. The system's dynamic response of different fault phases was analyzed based on the system's virtual prototype. Finally, the occasion of fault occurrence, spring's stiffness dropping to between 90% and 91% of primary value, is confirmed. The simulation result provides characteristic information for preventing and diagnosing fault.
