摘要
磨削淬硬技术在加工过程中因高温引发了工件热变形,导致加工后工件呈凹形,影响了磨削淬硬层的分布。本文通过ANSYS热—力耦合模块对磨削淬硬中的热变形进行了模拟分析,用时变磨削热流密度加载模拟得到结果与试验测量结果吻合性好。
The high temperature in grinding hardening induces workpiece thermal deformation.The thermal deformation causes a concavity on the ground profile and affects the grinding hardening depth. The paper uses ANSYS thermo-meehanieal coupling module to simulate the thermal deformation in grinding hardening.The workpieee profile by simulated with time-variant heat flux has good coincidence with the test result.
