Abstract

Bolt connections are widely applied in chassis suspension assembly; however, simulation analysis accuracy for bolt connections in vehicle durability tests is limited. Therefore, it is necessary to develop a calibration method for fastener dynamic torque in vehicle durability tests. This paper proposes a method of calibrating the fastening torque of the suspension based on durability, which avoids complex theoretical calculations and a wide variety of bench tests. Firstly, the reliability of the friction coefficient is guaranteed by rewriting the algorithm and designing a calibration test. Then, the stress and demanded tightening moments are calibrated by strain gauges and gantry. Finally, the calibration of the torque within a reasonable range is ensured by a tightening test. The experiment results show that the method can not only guarantee the connected reliability of the suspension system, but also solve the problem of torque attenuation accurately and quantitatively.
