Pre-stressed dry grinding can result in a hardened layer on the part surface while the surface residual stress is controlled. Considering the factors of the thermal field, pre-stress, and microstructural transformation, a proximate model of surface residual stress for pre-stressed dry grinding is established using the ANSYS finite element simulation method and verified through experiment. The variation laws and mechanisms of the residual stress along with the grinding parameters are revealed. Under the comprehensive effect of pre-stress and phase transformation, the residual stress of pre-stressed dry grinding is revealed mainly as compressive stress. This increases as the pre-stress and grinding depth increase. Under the coupling effect, pre-stress has larger influence on the residual stress than the grinding depth. The model can analyze and predict the residual stress of pre-stressed dry grinding in general.

考虑热，应力和相变耦合的预应力干磨残余应力模型

预应力干磨可以在控制表面残余应力的同时在零件表面形成硬化层。考虑到热场，预应力和显微组织转变的因素，采用ANSYS有限元模拟方法建立了预应力干磨表面残余应力的近似模型，并通过实验进行了验证。揭示了残余应力随磨削参数的变化规律和机理。在预应力和相变的综合作用下，预应力干磨的残余应力主要表现为压应力。这随着预应力和磨削深度的增加而增加。在耦合作用下，预应力对残余应力的影响大于磨削深度。
