Abstract
Taking the generator as research object, this paper was trying to determinate the parameters of vibration stress relief with a new method by the aid of finite element software with powerful function. Firstly, size and distribution of remnant stress were determined. Then the modality analysis and harmonic response analysis were carried on the workpiece by using the kinetics analysis function of finite element method. Finally, some crucial parameters of vibration stress relief were obtained.The research method and conclusion would provide the important reference values for casting enterprise to determine technological parameters of vibration stress relief.
