Research on Assembly Torque Attenuation of Steering Knuckle Cone Ball Stud
Journal Title: Automobile Technology & Material - Year 2024, Vol 39, Issue 2
Abstract
In order to eliminate abnormal sound of the knuckle cone ball stud of a passenger car on proving ground test, this paper proposed a new method based on virtual simulation. Firstly, the ball stud contact area variation tendency was simulated and the contact area critical preload was identified according to limit value of the road load data; then the residual preload under alternate working condition was simulated, and the residual preload was controlled larger than critical preload to avoid large contact area separation which will cause abnormal sound; finally,the tightening process was determined through joint test. The results show that this method can redefine the tightening torque, and the abnormal sound problem was eliminated successfully.
