Numerical Method in Dynamic Respones of Nonlinear Systems

摘要: 文[9]曾将一种模态综合技术推广到非线性系统的动态响应分析,应用于线性子结构具有非线性连接件耦合系统的振动分析.本文进一步把模态综合技术推广到各子结构具有非线性特性大型复杂结构的动态分析.文末给出的算例表明本方法具有良好的精确度和很高的计算效率.

Abstract: A kind of modal synthesis lechniques, which is applicable to vibration analysis for linear substructures wilh nonlinear coupling altachments, has been exlended to nonlinear dynamic analysis of large complex structural systems. In this paper, a process is suggestcd to dynamic analysis of large complex structural systems with nonlinear characteristics of each subslructure. At the end of this paper, an example shows the defendable accuracy of the results and high efficiency of this process.
