Analysis and optimization of static and dynamic performance simulation of large-scale crankshaft grinder

Based on the simulation analysis software Pro/ENGINEER, a three-dimensional geometric model and virtual prototype simulation model of the large-scale grinding machine was built. The sources of vibration were reduced greatly through the dynamic balance analysis in dynamics simulation module. And then through structural optimization in Pro/Mechanica environment, the static stiffness and dynamic stiffness of the grinding were improved. At last, through the above simulation analysis the static and dynamic characteristics of the grinding machine were improved, so that the accuracy of the crankshaft was effective guaranteed.
