| Abstract:To eliminate the micro-deformation of an engine body, and solve the problem that the size of liner installation base hole and the concentricity of the main bearing hole are out-of-tolerance, the vibratory stress relief technology based on harmonic spectrum technology is adopted through the comparison analysis of several aging processes. The VSR process program, procedures, and final effect are introduced and its economical efficiency is evaluated. The results show that the VSR technology could not only eliminate the micro-deformation of engine body, which is a kind of large thin-wall frame casting, but could also save manpower and material resources with the premise of ensuring the production cycle.Now the VSR has been put into application. |
