摘　　要：针对具有高性能要求的矿山机械装备零件需要严格把控加工过程,所以实时获取加工信息与控制加工过程对于优化加工工艺至关重要。传统的MBD方法能够将零件信息定义到三维模型中,但无法实时监控与控制加工过程。提出一种基于数字孪生的复杂零件动态建模方法,该方法可以构建矿山机械装备零件加工过程多物理、多维度的数字孪生模型。通过这种方法,建立了基于数字孪生的动态模型,包括几何模型、工艺模型等子模型,这些模型可以互相交互,并且能够实时展现矿山机械装备零件加工过程的动态变化与制造工艺的在线优化,给工艺优化提供思路。For mining machinery parts with high performance requirements,its manufacturing process should be strictly controlled,so it is very important to obtain processing information and control the processing process in real time for optimizing the processing technology.The traditional MBD method can be used to define the part information into the 3D model,but it can’t be used to monitor and control the machining process in real time.Therefore,a dynamic modeling method for complex parts based on digital twin was proposed,which could be used to build a multi physical and multi-dimensional digital twin model of mining machinery parts processing process.Through this method,the dynamic model based on digital twin was established,including geometric model,process model and other sub models.These models can interact with each other,and can show the dynamic changes of mining machinery parts processing process and online optimization of manufacturing process in real time,which provides ideas for process optimization.
