| Abstract: | Mathematics model of thermal-mechanical coupled dynamics close-loop system of automobile hydraulic damper was established by considering the mechanical damping property of damper,becoming hot and heat dissipation of damper.The influence of suspension frame system parameters of vehicle,structural parameters of damper and environmental factors was analyzed on the final equilibrium temperature of damper dubbing and the time needed for reaching the final equilibrium temperature,thus provided theoretical guidance for the design of damper. |
