【摘要】 基于Abaqus软件分析切削数值仿真中常见的沙漏问题,讨论沙漏问题的控制方法,比较不同沙漏控制方法的单元变形时序图和能量-时间曲线,能够直观判断沙漏变形的程度,通过细划网格和将力或约束分布到多个节点上,有效控制了沙漏问题。更多还原

【Abstract】 Based on the Abaqus,the FEM software,hourglass mode in numerical simulation of machining workpiece is analyzed.Hourglass control methods are discussed,and compared the energy-time curves of different control methods.It’s efficient to control the hourglass mode by refine mesh and distribute the force or constraint to several nodes.更多还原
