基于组件的几何约束求解新策略

New method based components for geometric constraint satisfaction problem

几何约束求解是智能CAD的核心问题 ,在研究装配模型的基础上提出了一种基于组件思想的约束求解策略。该策略将整个几何约束系统分为多个组合元 ,将循环约束约简为组合元中的边界元进行求解 ,并利用约束传播机制的局部性充分减小约束求解的规模。此约束系统求解策略可以应用于大型装配系统的参数化求解。

Geometry constraint solution problem is the core of intellect CAD system. Here a new method was proposed for solving it based on the idea of assembling the divided components. By dividing the dimension of constraint system to some assembly elements the constraint system can be deminished, and the local character can be utilized. The geometric constraint satisfaction problem can also be solved validly. The method for solving constraint system can be used for large scale assembling system
