摘　　要：生产节拍对以流水线为主要作业模式的孪生系统建模有重要影响,提出一种考虑节拍约束的断路器孪生车间模型动力学控制方法,对断路器单体和配套流水线进行运动检测,在节拍计算的基础上对孪生体进行动力学建模,通过驱动力加载、运动逻辑控制和切换,实现固定节拍和柔性节拍时流水线系统的孪生映射。建立了断路器上层、中层和下层多层方向包围盒及其层级遍历方式,提出对断路器孪生模型碰撞方向进行筛选,减少碰撞分离轴的检测数量。对比结果表明,孪生模型抖动减少,碰撞响应时间降低15%,碰撞精度提高96.26%。The production takt time greatly impact on the twin system modeling of assembly line. A dynamic control method of the twin workshop model is proposed, which considers the takt time constraints is proposed. Detecting the motion of the circuit breaker unit and the assembly line system, and the dynamic motion model of the circuit breaker twins are developed based on the takt time calculation. Through driving force loading, motion logic script controlling and switching, the twin mapping of the assembly line system is realized with fixed and flexible takt time as well. The circuit breaker’s directional bounding boxes and their hierarchy traversal methods are established. The upper, middle and lower layers from the direction of the twin model is filtered during collision to reduce detecting of collision separation axis.Comparisons results show that the twin model has less chattering phenomenon, the collision response time is decreased by 15% and the accuracy of the collision detection is increased by 96.26%.
