【摘要】 提出了一种求解链式结构系统的动力特性灵敏度的解析方法。首先根据结构系统振动的传递矩阵法建立了求解系统动力特性(固有频率和模态振型)的方程,在此基础上对系统动力特性的灵敏度进行了分析,导出了系统固有频率和模态振型对结构参数灵敏度的计算表达式。最后通过算例说明了文中模型的合理性和求解方法的有效性,并获得了一些有意义的结论。更多还原

【Abstract】 The problem of dynamic characteristics sensitivity analysis for the chain structures system is studied in this paper.The analytical method for calculating dynamic characteristics(natural frequency and mode) is given,the structure dynamic characteristics sensitivity is analyzed,and then the sensitivity expression is derived.Finally,the example shows that the computation expressions of sensitivity presented in the paper are rational and efficient.更多还原
