摘要
提出了具有变动阻尼结构的动态分析新方法，直接利用非比例阻尼矩阵计算位移函数和脉冲响应函数，求得功率谱和时间历程。另外提出了对应于随机激励的结构可靠性分析、可靠度随阻尼变动的灵敏度分析方法，并把该方法成功地应用于行驶在不平整道路上车辆的舒适性分析。
A method for the analysis of the dynamic response of structures with adjustadle non-proportional damping is presented. The power spectrum and time history can be obtained from the transfer function and impulse response function computed from the non-proportional damping matrix.In addition, a method is also Presented to estimate the reliability index of structures due to multiple random excitations by use of the transfer function,and to assess the sensitivity of the reliability index to variations of damping parameters. This method was successfully applied to the ride comfort optimization of a truck running on an unven road.
