Optimization of Two-State Adjustable Damping Shock Absorber

To improve the damping effect of vehicle shock absorber, a two-state adjustable damping shock absorber was designed using optimal design method. The size of the shock absorber damping hole and the valve parameters were optimized to obtain the optimal solution. According to optimal results, the piston speed and corresponding damping force of soft and hard damping conditions of the shock absorber were analyzed using MATLAB software. The results show that the simulated resistance curves and the ideal curves are in good agreement, which could provide guidance for the design and optimization of shock absorbers.
