During the working process, the vibrating feeder box is subject to fatigue damage due to the alternating load under the natural frequency. Therefore, attention should be paid to avoid stress concentration in the initial structural design, and the work efficiency can be improved while ensuring the reliability of the feeder. .

Taking the automobile chassis steering knuckle as an example, the reliability of the components in the steering system of the automobile is directly related to driving safety. Moreover, due to the particularity of the position, there are many connecting parts, and the structural design of the knuckle is limited by space. In addition, due to the complicated force situation, the impact load caused by the driving process of the car should also be taken into account in the design of the parts.

Traditional finite element software generally splits the large-scale components into small parts and analyzes them independently. The results obtained are also more precise, which is beneficial to the optimization of the organization, but it is time-consuming and labor-intensive. Simright simulator consider applying pressure on the working plane and applying a fixed displacement constraint on the moving chassis, thus simplifying the whole model into a common static problem.

In the gear transmission process, the stress values ​​of two aspects are mainly considered. One is the tooth surface contact stress and the other is the tooth root bending stress. These two stress values ​​are important forms for judging the gear failure. Simright simplifies the model by applying a unit force to simulate the transmission torque and applying a fixed-constrained analog gear mesh at the center of the hole.
