摘要：

In order to further improve the riding comfort of trackless rubber tire vehicle, to ensure the safety of coal mine underground transportation, a quarter vehicle of the dynamics equation was established for two-degree of freedom suspension system. And the underground road roughness value of the input signal was calculated. Then based on the Simulink module of MATLAB software, the mathematical simulation model of suspension system was built. The analysis result showed that the vibration of the wheel and the body of curve. Finally through the Simulink simulation model, the paper analyzed the suspension spring stiffness and damping coefficient change on the influence of vehicle vibration system performance indicators. Simulation results showed that when the suspension spring stiffness was 223.5kN/m, the suspension damping coefficient was 1.91 kN s/m, the trackless rubber tire vehicle anti-vibration effect was best, and its vibration characteristic was relatively sensitive to the change of spring stiffness. The results for coal mine underground trackless rubber-tyred vehicle suspension system provides theory basis for the design and structure optimization.
