摘要
针对航天精密复杂产品技术状态多变带来的装配调试效率和一次装配合格率偏低等问题,提出基于数字孪生的航天产品自适应装调方法。通过装配体关键特性分析、识别与测量快速构建装配体孪生模型,采用多传感器对产品装配状态进行实时测量和虚实同步,由孪生模型驱动进行可装配性仿真分析、装配路径动态规划与精准控制,在此基础上,搭建航天产品自适应装调原型系统,试验结果证明本方法在复杂产品装配过程闭环控制和高质高效装配中具有较强的可行性和推广价值。
Aiming at the problems of assembly and adjustment efficiency as well as low pass rate of one-time assembly caused by the changing technical status of aerospace precision and complex products,a digital twin-based adaptive assembly and adjustment method for aerospace products is proposed.Through the analysis,identification and measurement of the key characteristics of the assembly,the twin model of the assembly is quickly constructed.Besides,the assembly status of the product is measured in real time using multiple sensors and the real and virtual status is synchronized.Moreover,the twin model is driven to perform assembly simulation analysis,assembly path dynamic planning and precise control.On this basis,a self-adaptive assembly and adjustment prototype system for aerospace products was built.The test results proved that this method has strong feasibility and promotion value in closed-loop control of complex product assembly process and high-quality and efficient assembly.
