摘　　要：归纳了残余应力的基本类型及各类残余应力的计算机仿真方法,概述了残余应力形成与演化行为及残余应力调控技术的研究现状。以机械臂基座本体淬火过程为例,展示了有限元仿真在大型复杂构件残余应力演化行为分析上的应用;以工字型材模压去应力为例,通过有限元仿真重现了变截面构件模压去应力的过程并分析了模压去应力的影响因素。讨论了残余应力仿真预测与调控技术应用于组件及其涵盖构件制造-服役全寿命周期的可行性,预测了其集成于智能制造技术体系的巨大潜力。The classification of residual stress(RS)and the corresponding method for simulation in each scale are summarized.The studies focusing on the evolution and regulation of RS are summarized to demonstrate the development in the field.The fruits from simulating the evolution of RS in large and complex components are demonstrated,taking the quenching process of a manipulator base as an example.The effect of reducing RS via compression in components with varying section is discussed,taking the die forging on an I-section bar as an example.The development of simulating&control technology of RS toward the applications along the whole life cycle,or in the assembled components,together with its potential to be integrated into the intelligent manufacturing,is predicted.
