Co-simulation of rigid-flexible coupling system for turn-milling center

Aiming at the problems of selection for motor parameters and mechanism design of the turn-milling centre, the model of the machining centre is simulated kinematically and dynamically by virtual prototyping technology. A 3D model of the machining centre is developed by UG software, and the assembly model is transformed into ADAMS to form a virtual prototype simulation model based on multi-body dynamics. In order to get more accurately the dynamics of turn-milling centre in the simulation process, the co-simulation method using ADAMS and ANSYS is put forward in the paper, and its important components are regarded as flexible bodies and other parts are rigid bodies to form the rigid-flexible coupling system. The designers cannot only observe the three dimensional dynamic movements in the virtual circumstance by the method, but also forecast accurately and solve possible problems during design before the prototype is manufactured, assuring the feasibility of the motor selection and designs for mechanism framework and control system, shortening the period of the product design and reducing the cost of production.
