Implementation of Bounding Box Interference Checking Based on Pro/E

碰撞干涉检查在产品装配仿真中起着重要作用,包容盒方法可以有效地解决干涉检查固有的计算复杂性。根据产品零部件不同类型提出了三级精度包容盒相结合的快速干涉检查算法,并在Pro/EN-GINEER环境下加以实现。通过人机交互界面应用于汽车变速器装配仿真过程中零部件之间的碰撞干涉检查。

Collision and interference detection plays an important role in virtual assembly of mechanical product. This method can decrease the intrinsic computational complexity of Collision and interference detectioneffectively. According to different type of product parts, a fast algorithm combined plain grade and bounding box for detecting collision and interference is introduced and implemented in Pro/ENGINEER thispaper. It is applied to the collision interference detection between the parts of automobile transmission in the process of virtual assembly by method of manachine interface.
