The traditional vehicle suspension vibration reduction design method uses a fixed damping coefficient to reduce the vibration of the elastic element, and does not consider the different vibration intensity caused by different road conditions and vehicle speeds, and the vibration reduction effect is poor. A finite element design method for vehicle suspension shock absorption optimization is proposed to analyse the function and structure of vehicle suspension shock absorbers. We use the first-order optimization method in the ANSYS finite element software to carry out the optimal design of vehicle suspension damping, and take the damping force of the suspension shock absorber as the optimization objective to carry out the finite element optimization design of the vehicle suspension damping. This ensures that the vibration of the vehicle body is rapidly attenuated, so that the body can quickly reach a stable state. The results show that the fuzzy control strategy can greatly suppress the acceleration of the vehicle body and the dynamic load of the tire, reduce the dynamic travel of the suspension, and the ride comfort, driving safety and operation stability of the vehicle have been significantly improved, and the system suspension has a good comprehensive performance. |
