基于 GO 法的车用发动机增压系统可靠性分析

摘要

Taking the vehicle engine turbocharging system as an example ,the calculation of dynamic availability was conduc‐ted by direct algorithm ,correction algorithm and exact algorithm of GO method .Compared with the FTA and Monte Carlo Simulation results ,the accuracy and applicability of GO method to the reliability analysis of turbocharging system for vehicle engine were verified .%以车用发动机增压系统为例，分别采用 GO 法直接算法、修正算法和精确算法进行了动态可用度计算，并且基于 GO 法对系统进行定性分析。通过与故障树、蒙特卡洛仿真结果对比，验证了 GO 法对车用发动机废气涡轮增压系统可靠性分析的正确性和适用性。
