摘要： A method for executing water jet peening for giving an impact force to a surface of a structure member by a crushing pressure of a water jet and cavitation and improving residual stress, or washing, or reforming said surface,wherein said water jet peening is executed so as to make a natural frequency of oscillation of said structure member and a excitation frequency of oscillation of water jet peening different from each other.

摘要翻译： 一种执行喷水喷丸处理的方法，其通过水射流和气蚀的破碎压力向结构构件的表面施加冲击力，并改善残余应力或洗涤或重整所述表面，其中所述喷水喷丸处理 以使所述结构构件的固有振荡频率和水喷射喷丸的振荡的激发频率彼此不同。
