Abstract:
To study isolation performance of rubber suspension and improve ride comfort of off-road vehicle, the lumped-mass model of engineering dump truck with eight degrees of freedom is set up on the foundation of rubber components and rubber suspension tests, which includes hardening cubic stiffness and bilinear damping characteristics. The mathematical model is solved by fourth-order Runge-Kutta implicit scheme and validated by test. Both simulation and test results reveal that the stiffness and damping coefficients of rubber suspension need to be optimized to improve ride comfort of whole vehicle. The most suitable optimized parameters are achieved according to sensitivity analysis. Simulation results show that the optimum stiffness and damping values can be obtained when the effective constraints are considered in optimization. This study lays a foundation for the optimization of off-road vehicle rubber suspension.
