摘要:
采用DEFORM-3D对锻造过程进行仿真计算精度很高,但基于图形的动画效果不理想,不能提供交互可视化.因此,提出了基于DEFORM-3D和Open Inventor实现虚拟锻造仿真的新方法,通过C++编码实现几何模型数据格式的转换,使Open Inventor可读入有限元计算的几何模型,并运用Open ln-ventor 的传感器机制、引擎机制等,完成十字轴几何模型的塑性变形和上模的下压运动,且在Open ln-ventor平台上实现锻造过程的虚拟仿真.
Abstract:
The finite element analysis software DEFORM-3D can be used to simulate forging process,and itsprecision is high,but the animation based on graph is not ideal at present,the post processor can not provideinteractive visualization.So a new method based on DEFORM-3D and Open Inventor to achieve the virtualsimulation of forging has been proposed.Using C ++ to achieve conversion of two data formats,so that theOpen Inventor can read in the geometric models of finite element calculation.Using the sensor mechanism ,engine mechanism and so on,we complete the movement of top die and plastic deformation of cross shaft dur-ing forging,realize the virtual simulation of forging process on Open Inventor platform.
