Abstract: Fatigue test can verify the fatigue life of chassis parts rapidly. In addition, it can promote the upgrade of products and control costs. In this paper, we will have a discussion about the road spectrum acquisition and transformation, which includes the arrangement and calibration of strain gauge and theory of the road spectrum transformation.

Keywords: road spectrum transformation; fatigue strength theory; arrangement and calibration of strain gauge
