基于CATIA 二次开发的驱动轴运动分析方法

Driving shaft motion analysis based on CATIA secondary development

文章利用CATIA自动化对象技术,通过VB对CATIA进行二次开发,研究将复杂的驱动轴运动校核过程用程序进行封装。设计人员仅需要在含有驱动轴的悬架DMU运动模型基础上提供简单的驱动轴相关的参数,即可完成驱动轴的运动校核过程,程序将以Excel的形式自动输出所需要的结果。设计人员可通过该结果进行驱动轴后续的分析与校核,基本实现了提供输入,马上得到输出的结果,省去了中间大量的复杂的操作过程,提高了工作效率。结果表明,文章所述的二次开发程序对于驱动轴的运动分析校核有较大的应用价值,降低了出错率,缩短了开发周期。

Using CATIA automation technology of secondary development,this paper studies encapsulating the process of driving shaft motion analysis with VB program.Designers only need to provide simple parameters of driving shaft in DMU,then it will complete the driving shaft motion analysis process.The program will output the required results in the form of excel automatically.The designers can complete the following analysis and check of the driving shaft.The program realizes output the results immediately with the input,eliminating a lot of complicated operation process,and work efficiency is improved.The results show that,the secondary development program described in this paper has great application value or the driving shaft motion analysis and check,which reduces the error rate and shortens the development cycle.
