摘要
在虚拟样机仿真分析可行性得到论证的基础上,介绍了一种基于虚拟样机技术的高速冲床执行机构有限元分析方法;采用SolidWorks、ANSYS和ADAMS联合仿真的关键技术,建立高速冲床执行机构的多刚体及刚柔耦合的虚拟样机模型,对其进行仿真分析,比较了两者的仿真结果,得出刚柔耦合模型更能反映机构的真实运动;根据仿真得到的执行机构中柔性体的动态载荷,然后将载荷数据导入有限元分析软件ANSYS中,对其进行有限元优化分析,为执行机构各构件结构的设计优化提供依据。
On the basis of the proved feasibility for virtual prototype simulation analysis,the virtual prototype actuator of the high-speed press finite element analysis method based on the technology was introduced.Using the key technology of combined simulation based on SolidWorks,ANSYS and ADAMS,the multi-rigid and rigid-flexible coupling virtual prototype models of the press actuator were established and the difference of the results after the kinematic simulation was compared.The conclusion shows that the rigid-flexible coupling model reflects more accurately the real movement.The dynamic load of flexible body was obtained by the simulation,then the data were induced into finite element analysis software ANSYS,and finally the finite element analysis was conducted which provides the basis for structural component design of the actuator.
