| 摘 要： | 用非线性随机振动的理论讨论了油气悬挂车辆被简化为二自由度时的响应,得出了响应均值方差的计算公式,并且指出由于油气悬挂的非对称性,在零均值激励下,系统的响应也是非零均值的。这一点在林耀群等的《油气悬挂车辆的非线性随机振动》一文中未能得到。同时,还讨论了在激励强度变化时均值的变化情况。

| Abstract: | The response of hydropneumatic suspension in vehicles regarded as having two - degrees of freedom is discussed applying the theory of nonlinear random vibrations . The formulae for the means and variances are given . It is pointed out. in this paper that.a system will have non-zero mean response under zero mean excitation . This conclussion has not been arrived at in the paper by Lin Yaoqun and other . Also discussed the variations in means and variances with variable excitations . |

| Keywords: | nonlinear vibration random vibration stochastic differential equation/ nonlinear random vibration equivalent linearization . |
