In order to shorten the period and reduce the cost of reliability test, reliability enhancement test combined with virtual testing technology was applied to a system. The abrasion failure in a mechanical system was taken as a research object. Through theoretical analysis of abrasion test, the abrasion enhancement test mechanism was determined, and the principles of determining virtual enhancement testing technology were presented. The formula for abrasion enhancement coefficient was deduced. Furthermore, the corresponding calculation was programmed by use of MATLAB. Based on the virtual prototype of a breech system, concrete enhancement test was performed on shock abrasion parts with plane contact. And the enhancement test technology scheme was constituted. The testing results showed that the adopted enhancement test technology is feasible. The study results were helpful for application of virtual testing technology in reliability enhancement test.
