摘　　要：为了分析振动传递路径系统各振源的重要性,保证工程人员能够快速有效地进行振动噪声控制,采用分离法对多激励作用下的7自由度振动传递路径系统进行分析,在频域内计算了各振源被分离时接受体能量的插入损失,由此定量地评价了各振源的重要性.通过算例表明提出的方法切实可行.In order to analyze the importance of vibration sources,the partition method is applied to analyze a 7-DOF vibration transfer path system under multiple excitations.This can guarantee the prompt and effective responses from engineers to control vibration noises.Within the frequency domain,the insertion losses of energy receivers are calculated during vibration source partition.As such,the quantitative importance evaluation is conducted on vibration sources.Based on the computational examples,it is indicated that the proposed method is feasible.
