The Gears System Reliability Analysis with Correlation among the Components of Gear Box in Self-Propelled Gun

Against the accurately solving of system reliability was inadequate, the Copula function was applied in system reliability analysis of weapon equipment, the paper established system reliability model which obtained the second shift single driving, and obtained the common relationship between travel and system reliability degree, it tested that Copula function was better to solve correlation problem in the system reliability model .It provided a method for system reliability analysis and reliability susceptive analysis.
