摘　　要：研究一类强非线性缓冲包装系统的随机可靠性。用基于广义谐和函数随机平均法将系统状态方程转化关于幅值与相位差的平均伊藤随机微分方程,建立并求解相应的后向Kolmogorov方程,得到系统的条件可靠性函数。最后,用Monte Carlo模拟法验证理论解的正确性。The stochastic reliability of a strongly nonlinear cushioning packaging system was studied.First,the equations of system state were converted into the averaged ito stochastic differential equations of amplitude and phase by the stochastic averaging method;then the related backward Kolmogorov equation was established and solved to yield the conditional reliability function of the system.Finally,the Monte Carlo simulation was proposed to verity the analytical solution.

关 键 词：强非线性 包装振动系统 随机平均法 可靠性
