The refined algorithm of generalized density evolution equation based on reproducing kernel particle method
摘要
Abstract
The response of dynamic systems can be approximated by the particle approximation or the reproducing kernel particle method.The refined algorithm of generalized density evolution equation is developed based on the reproducing kernel particle method.The steps of the refined algorithm are detailed in the paper.Through the system of a single degree of freedom as an example,the accuracy of the refined algorithm is investigated based on the PDFs of the response.Then through a stochastic sturcture of multi degrees of freedom as an example,the refined algorithm based on the reproducing kernel particle method can slove the nonlinear stochastic system.关键词
