【摘要】 应用伪随机实验技术和随机减量技术以及特征系统实现算法(ERA 法)为动态子结构之问的振动耦合判定提供了一种有效的实用模式.以某汽车发动机悬置系统一车架作为实例,判别了它们之间的振动耦合情况,取得了良好的效果.本文所用振动耦合识别模式可作为解决工程问题的有效方法.更多还原

【Abstract】 By using pseudo-random experiment technique,random decrement andEigensystem Realization Algorithm(ERA),this paper provided a practical pattern for vi-bration conjunction judgement of dynamic substructure.As an application example,thevibration conjunction between engine mount and chassis frame has been judged and bet-ter results have been achieved.The vibration conjunction recognition pattern used inthis paper can serve as one of efficient methods solving engineering problems.更多还原
