摘要
本文研究由非线性隔振器耦联线性子结构形成的组合结构的动响应预估。基于实测子结构的脉冲响应函数,建立了组合结构的对接边界积分型动力学方程;找到了将其转化为标准常微分方程组的途径;用实验考核了上述方法。
The paper deals with dynamic response prediction of composite structures which consists of two linear components coupled by some nonlinear vibration isolators. Based on the measured impulse response functions of the linear substructures, three kinds of dynamic equations of interfacial integeration are proposed and a procdure to transfrom the dynamic equations of integeral type into a set of ordinary differential equations is suggested. Computer simulations and a real test are given to verify the effectiveness of the theoretical results.
