Basic Connection Method of Automotive Steering Knuckles

The steering knuckle is primarily connected to the vehicle body via three bushings and two bolts. It also connects to the braking system through the brake mounting holes on the flange. At high speeds, road vibrations are transmitted to the steering knuckle via the tires; this transmission path is crucial for our steering knuckle analysis. In the calculations, we used a pre-built vehicle model and applied a 4G gravitational acceleration to calculate the support reactions at the center points of the three bushings and the two bolt mounting holes of the steering knuckle, which were then used as the applied loads. To ensure accuracy, we constrained 123456 degrees of freedom at all nodes on the flange connection to the braking system end face.
