摘　　要：应用频谱谐波技术对切割机的底座进行了振动时效处理,并采用金属磁记忆应力检测法测试了工件振动时效前后的残余应力。结果表明,频谱谐波振动时效技术能够有效降低并均化底座的残余应力,可广泛用于大型铸件残余应力的消除。The bases of cutting machine were treated by VSR technology with harmonic frequency spectrum, and the residual stress distribution in the workpieces before and after VSR was tested with metal magnetic memory stress detection method. The results show that the VSR technology with harmonic frequency spectrum can effectively reduce and homogenize the residual stress in the bases. The technology can be applied to eliminate the residual stresses in large size castings.
