随着工艺技术的不断发展,振动时效技术在生产中已得到日益广泛的应用。为得到满意的处理效果,必须根据具体情况,在振动时效过程中调整激振力,使工件产生满足下列条件的动应力。 σ_b>σ动+σ残≥σ_s 式中:σ_b—抗拉强度; σ_s—屈服强度 σ残—工件残余应力 σ动—工件动应力。
With the continuous development of process technology, vibration aging technology has been increasingly used in production. In order to get a satisfactory treatment effect, it is necessary to adjust the exciting force in the process of vibration aging according to the specific conditions so that the work piece can generate dynamic stress satisfying the following conditions. σ_b> σ motion + σ residual ≥ σ_s where: σ_b-tensile strength; σ_s-yield strength σ residual-workpiece residual stress σ-dynamic workpiece dynamic stress.
