Then we present the application flow of virtual prototyping technology to the development of mechanical products. Based on ADAMS/VIEW, a new kind of special machine rotating cutter has been developed. The simulation results show that the rotating cutter meets the design requirements. It is concluded that virtual prototyping technology is quite valuable in designing and manufacturing mechanical product.展开更多

Based on ADAMS/VIEW, a new kind of special machine rotating cutter has been developed. The simulation results show that the rotating cutter meets the design requirements. It is concluded that virtual prototyping technology is quite valuable in designing and manufacturing mechanical product.
