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 spectrum harmonic technology was used to vibrate the base of the cutting machine and the residual stress before and after vibration aging was tested by metal magnetic memory stress testing. The results show that the spectrum harmonic vibration aging technology can effectively reduce and homogenize the residual stress of the base, which can be widely used to eliminate the residual stress of large castings.
