Numerical Simulation for Technological Parameters of Vibratory Stress Relief in Large Welding Structures

Article Preview

Abstract:

In order to obtain the natural frequency, vibration mode and the curves of amplitude-frequency under two supporting ways, dynamic analysis was carried out on the large plane steel gate structures of a hydraulic projects. According to the Chinese machinery industry standard of vibration stress relief, technological parameters and effective range of vibratory stress relief were determined under two supporting ways. Some valuable references of determining technological parameters of vibratory stress relief for the plane steel gate structures and other momentous welding structures were provided through the research results and the conclusions.
