ABAQUS/Plug-ins在炮身参数化建模及模态分析中的应用

Application of ABAQUS/Plug-ins in the Parametric Modeling and Mode Analysis of Gun Barrel

针对火炮炮身的模态参数在测量次数、测量数据的准确性方面难以得到充分保证的问题,提出一种利用ABAQUS软件二次开发功能制作火炮炮身的参数化建模及模态分析插件的方法。运用ABAQUS自带的RSG编制炮身的参数化建模界面与模态分析图形界面,并编写对应的内核脚本程序使其成为完善的图形界面,研究了温度及质量变化对炮身模态的影响,实现了快速创建、修改模型等参数化操作。分析结果证明:该方法提高了分析效率,对炮身的固有模态分析和研究提供了有力支持。

To the question that it＇s difficult to sufficiently ensure the accuracy of measurement times and measuremfnt data of mode parameters of the gun barrel, a method that uses secondary development function of ABAQUS software to fabricate parametric modeling and mode analysis plug-ins of gun barrel is proposed. Utilize ABAQUS＇s own RSG to establish the parametric modeling interface and mode analysis figure interface of the gun barrel, meanwhile, compile corresponding kernel script to perfect it. Have researched the influence of variations of temperature and mass on gun barrel model and achieved parametric operation of establishing quickly and modifying model, etc. The consequence proves that this method enhances analytic efficiency and forcefully supports for gun barrel＇s nature mode analysis and research.
