摘　　要：为了设计时不对材料造成不必要的浪费,探究了SolidWorks simulation在静应力分析中应力和位移的准确性,采用9种不同网格参数和网格密度进行组合研究,得出如下结论:最大应力值通过ISO剪切,当单元体积剩余百分比小于4%时,则此时的应力值较接近真实值。模拟与理论计算最大位移相对误差小于0.2%,可见模拟的最大位移真实可靠。本研究为SolidWorks simulation静应力分析中应力和位移的准确性提供了可靠的理论依据。In order to design without unnecessary waste of materials,the accuracy of SolidWorks simulation for stress and displacement in static stress analysis was explored,and a combination of nine different mesh parameters and mesh densities was used to investigate the following conclusions:The maximum stress value is sheared by ISO,and when the remaining percentage of cell volume is less than 4%,then the stress value is closer to the true value at this time.The relative error between simulated and theoretically calculated maximum displacement is less than 0.2%,which shows that the simulated maximum displacement is real and reliable.This study provides a reliable theoretical basis for the accuracy of stress and displacement in SolidWorks simulation static stress analysis.
