振动时效应力消除可靠性探讨

The Reliability Discussion of Vibrating Stress Relief

通过分析热处理与振动时效消除应力的原理,开展了对同一试验件在初始状态、振动时效后和热处理后三种状态下的对比试验,检测了三种应力消除方式试验后具体应力值,得出三种消除应力方式的应力消除率,验证了振动消除应力在零件加工中的消除应力和控制零件变形的有效性。

By analyzing the principle of stress relief by heat treatment and vibration stress relief, the comparative tests of the same test piece under three states of initial state, vibration stress relief and heat treatment are carried out. The specific stress values of three stress relief methods after test are tested, and the stress relief rates of three stress relief methods are obtained, which verify the elimination of stress in part processing and effectiveness of controlling part deformation by vibration stress relief.
