摘要: 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.

关键词: differential equation with variable coefficients, equivalent parameter, solution in the domain, solution of semi-analysis
