Research and Application of utomation Create of Dimensional Chain Equations under CAD Environment

在军工产品特别是自动化武器的设计中尺寸链计算有着极其重要的作用。为了进一步提高效率 ,减少错误并实现尺寸链计算全过程的计算机化 ,将矢量推算法引入到方程组的生成中。利用已有CAD装配图拆分小图中直接提取尺寸信息 ,通过尺寸矢量推算算法自动生成方程组 ,并进行了实际应用 ,应用结果表明该方法适用于任何形式的装配图拆分小图 ,能大大的减轻技术人员的劳动强度 。

Dimensional chain calculation plays an extremely important role in martial productions, particularly auto weapon design. In order to performance higher efficiency, reduce mistakes and realize computerized course of calculation, is vector organum method introduced in calculations. How to directly get dimension information from split graph of assembling graph, and create equations automatically by vector organum method are introduced. The results of application indicate that the method suits any case of split graph of assembling graph, can relieve fatigue of the engineers, and got perfect effects.
