| Abstract: | This paper details a dynamic shock absorber model using the Rebrouck method,the influence of displacement,velocity,acceleration,frequency,and temperature on damping characteristics is considered.The constituent parameters of an ATV’s right-rear shock absorber are obtained using Levenberg-Marquardt optimization algorithm and five group experimental data,and the test data agree well with the calculation.Finally,the dynamic model is incorporated into an E-class full vehicle model(CarsimTM) using S-function.The vehicle’s behaviors are compared with the results obtained with the classical shock absorber representations under frequency sweep and double lane change conditions. |
