摘　　要：从工程应用的角度出发,针对钢丝绳隔振系统在随机载荷作用下的加速度响应特点,认为系统在特定状态下可以用线性模型来描述,但其中参数会随试验状态的变化而改变。通过建立不同状态下的系统线性模型,证明了在一定试验量级范围内,用线性模型描述非线性特性是可行的。研究方法及成果便于设计人员参考。From view-point of engineering application, the acceleration characteristic of a wire-rope isolator under stochastic load is studied. It is considered that the isolation system could be described by using the linear model under a certain experiment state, while its parameters would be changed along with changes of the experiment state. Here, the linear model of the isolation system under different experiment states is built. It is demonstrated that it is possible to describe the nonlinear characteristic of the isolator by using the linear model under some certain range of test level. The proposed method and the results could be references for designers.
