中文摘要：
研究失谐对耦合摆链结构失谐后振动特性的影响。建立无量纲化的耦合摆链系统运动方程,采用振型分解法求解其动力响应。以5自由度和7自由度耦合摆链结构为例,分析耦合摆链结构的振动模态及在engine order形式的激振力下的动力响应。根据得到的结果,对系统由于失谐而出现的模态局部化、振动局部化、峰值分裂等现象及它们的联系进行深入讨论。
英文摘要：
The effects of mistuning on vibration characteristics of coupled pendulum system were studied.Using the mode decomposition method,the motion equations of the system in a dimensionless form were derived.As the example,the modes of vibration and the forced vibration responses excited by engine order excitation for a 5-DOF(degree of freedom) and a 7-DOF coupled pendulum system were analyzed.According to the results,the relations between the phenomenon of vibration mode localization and frequency response local...
