本文针对机械系统动态设计的需要,从动力修改原理出发,导出了一种多阶固有频率的动态修改方法。本方法只需给出试验模态分析结果就可以完成所需全部计算。
In this paper, a dynamic modification method for multi-order natural frequency is derived from the principle of power modification for the needs of dynamic design of mechanical systems. This method only needs to give the test modal analysis results to complete all the calculations required.
