ABAQUS二次开发在发射场坪参数化建模与分析中的应用

摘要

发射场坪是发射系统的重要组成部分,为了能够快速准确地建立含场坪效应的发射装备非线性有限元动力学模型,实现仿真分析的自动化,引入ABAQUS二次开发技术,利用ABAQUS自带的RSG编制发射场坪参数化建模分析的插件界面,并编写对应的内核脚本程序与之级联,级联成功之后即可实现场坪建模、分析的参数化操作.该方法避免了重复建模,有效提高了仿真分析过程的自动化程度,为场坪的响应特性研究提供了有力的支撑.%Launching site is an important part of launching system,in order to establish nonlinear finite element dynamic model of launching system which includes launching site accurately and quickly and realize the automation of simulation analysis ,the secondary development of ABAQUS is introduced. Utilize ABAQUS's own RSG to establish the parametric modeling interface and analysis figure interface of the launching site,meanwhile,compile corresponding kernel script to connect with it. After a successful connection,the parametric modeling and analysis of launching site can be achieved. This method can avoid repeated modeling and effectively improve the automation of simulation analysis process,providing a strong support for the response analysis of launching site.
