Outline
On the basis of the actual structure of the linear hydraulic shock absorber of the medium and low speed maglev vehicle, the AMESim simulation model of the linear hydraulic shock absorber was established and verified. The maximum simulation error of the established hydraulic shock absorber simulation model is only 8.6%, and the reliability is high. Combined with the model of hydraulic shock absorber and maglev vehicle structure, the co-simulation model of shock absorber and vehicle system was established. From the perspective of dynamic optimization design, the installation quantity and layout position of lateral shock absorber were designed, and the influence of different installation modes of lateral shock absorber on the stability of maglev vehicle was discussed. The dynamic calculation results show that the installation modes of lateral shock absorber has little effect on the vertical stability of maglev vehicle.When 8 lateral shock absorbers are installed on the suspension frame of a single car, the vehicle stability is the best. When the suspension frame of a single car is equipped with 4 lateral shock absorbers, the vehicle’s ride stability performances takes the second place. When the lateral shock absorber is not installed, the lateral ride stability performances of the measuring points at the end of the vehicle exceeds the excellent limit.
