首发时间:2009-06-18
摘要:本文介绍了采用粒子群算法反演物理力学参数的基本步骤,然后结合通用的商业有限元软件MSC.Marc,并利用其与FORTRAN语言的接口,编写了基于MSC.Marc的物理力学参数的粒子群算法反演程序。文中结合陈村大坝的实测资料,利用该方法反演了大坝坝体弹性模量。算例表明,采用粒子群算法和MSC.Marc反演大坝坝体的物理力学参数是可行的。

Inverse Analysis of Mechanical Parameters of Dam Based on PSO
Abstract:This paper describes the basic steps of inversing physical and mechanical parameters by using PSO, then combined with a common commercial finite element software MSC.Marc and using their language and FORTRAN interface, particle swarm optimization inversion procedure of the physical parameters based on MSC.Marc is written. In light of the monitoring data of Chenchun Dam, this paper inverses the elasticity modulus of deformation of the dam by using the same method. The example shows that the inversion of physical and mechanical parameters of dam and dam foundation by using PSO and MSC.Marc is feasible.
Keywords: PSO dam inverse analysis mechanical parameter
