| 目的 提供一种具有通用性的虚拟装配零部件设计方法，能够实现多位置、多旋转状态判定的装配方式与灵活的装配序列规划。方法 首先使用多个定位触点进行碰撞检测来确定零件的位置和旋转状态，然后使用二进制整数作为零件状态码表达零件间的装配依赖关系，最后通过二进制运算表达式的校验算法限制零件状态码的取值决定零件是否可以装配，从而达到装配序列的约束规划。结果 在装配方式上使得所有零件具有通用的设计方案，针对特殊零件只需要设置特殊定位触点，在装配序列规划上实现了多种灵活的装配顺序设计，装配逻辑关系表达更加清晰。结论 通过多触点定位和状态校验可以实现具有很好通用性和扩展性的虚拟装配技术。 |

| The work aims to provide a general design method for virtual assembly parts, so as to realize the assembly method of multi-position and multi-rotation state determination and flexible assembly sequence planning. Firstly, multiple positioning points were used for collision detection to determine the position and rotation status of the part, then the binary integer was adopted as the part status code to express the assembly dependency between the parts, and finally the verification algorithm of the binary operation expression was applied to limit the value of the part status code to determine whether the parts could be assembled, thus achieving the planning of assembly sequence. The assembly method made all parts have a general design scheme. For special parts, only special positioning points were required to be set. In the assembly sequence planning, a variety of flexible assembly sequence designs were achieved, and the assembly logic relationship was more clearly expressed. Through multi-point positioning and status verification, a highly versatile and extensible virtual assembly technology can be realized. |
