Abstract
The reason for the axle force attenuation of the chassis bolts is explained, and the calculation method of the axle force attenuation of bolts is provided. Through the calculation examples of the three chassis parts and compare with the test results of the axle force attenuation, the calculation accuracy is verified. At the same time, through the structural differences and test results of these three parts, the factors affecting the attenuation of the axial force are analyzed and explained. Accounting the test of the axial force attenuation, the tightening axial force and attenuation are quantitatively managed to ensure the bolt tightening reliability, thereby enhancing the reliability of the vehicle.
