| Abstract: | In this paper,improvement of surface property and fatigue strengthof connecting rods by shot-peening is described.After process by shot-peening,whilethe protuberance height attained to 0.70 mm,fatigue strength increased by 19%,upto 440 MPa. Fatigue test results of original connecting rod indicated that the covering rate of shotpeened surface influenced surface sturdiness.The stress distribution of shot-peeningstrengthening surface,determined by x-ray delecting instrument is also presented. |
