| 摘 要： | 根据振动时效对动应力分布的要求及压力容器的结构特点，通过对容器结构的固有频率、固有振型及其相应的动应力的分析，提出采用声激振来消除焊接残余应力以达到时效的目的，并在压力容器上成功地进行了声激振试验。

| Abstract: | The requirement of the time-effect of vibro-acoustics for the distribution of the dynamic stress and the structural characteristics of the pressure vessel are first explored. By analyzing its modal parameters and dynamic stress, a new method of sound excitation is given for eliminating the welding residual stress to achieve the time-effect. It is proved successful in practice. |
