Abstract
本发明公开了一种多体分离CTS轨迹捕获风洞试验模型防碰撞方法，涉及风洞试验领域，通过将各分离模型、支撑和可能碰撞的机构简化模型重新组成装配体建立多个独立模型组件，通过在各独立模型组件表面建立三角形网格，防碰撞检测系统读取模型网格，显示网格图形，初始化位置姿态；CTS运行系统将下一个轨迹点通过TCP / IP协议传输给防碰撞系统；防碰撞软件模拟该运行轨迹，通过空间均匀划分法计算两个模型网格点之间最小距离，根据距离是否小于阈值判断模型是否碰撞，将碰撞情况传给CTS运行系统，CTS运行系统接收到碰撞的信息则停止机构运行。本发明的防碰撞方法具有较高精度和实效性，解决了风洞CTS试验模型的模型组件磕碰难以监测和规避问题。
