Research on Reliability for Armored Vehicle Mechanical System Based on Copula Function

The article research reliability of the drive gear wheel and follower gear for armored vehicle mechanical system using Copula Function.The system reliability and rate of failures are deduced.At last,The article get that the reliability based on Copula theory approach the fact by comparing the reliability of the system under the presumption that all the parts of the gear driving box are independent of one another and analyzing the change trend of the reliability calculated with two methods.
