In order to shorten the period and reduce the cost in reliability testing, Reliability Enhancement Testing combined with virtual testing technology was applied to systems. The abrasion failure in mechanical system was taken as the research object. Through theory analysis of abrasion testing, the abrasion enhancement testing mechanism was confirmed, and the principles of confirming virtual enhancement testing technology were put forward. The formula for abrasion enhancement coefficient was deduced. What’s more, corresponding calculation was programmed by use of MATLAB. Based on the virtual prototype of breech system, concrete enhancement testing was carried out on shock abrasion parts with plane contact. And the enhancement testing technology scheme was constituted. The testing results show that the adoptive enhancement testing technology is feasible. The research could conduce to advance the application of virtual testing technology in Reliability Enhancement Testing.
