Research On Dynamic Loads Of The Vehicle Wheels

The two-degree-of-freedom vibrating model of vehicle is studied in this paper. Using the pseudo excitation method, the effect of manifold factors on the random dynamic loads of the wheels is analyzed. The main contents of this paper are as below:1. The pseudo excitation method is used, the road surface condition is turn into the confirm import, based on the two-degree-of-freedom vehicle model, the effects of the vehicle speed and the roadway surface condition on the random dynamic loads of the wheels are analyzed.2. The inverse pseudo excitation method is used, the power spectral density of the road is calculated via the random dynamic loads of the wheels.3. Several methods of reducing the random dynamic loads of the wheels are put forward, such as reduce the vehicle speed and so on.4. The effect of the vehicle speed and roadway surface condition on the dynamic respond of the wheels is analyzed by using the soft of ADAMS.In conclusion, some inherent rules are mainly studied in this paper, the effects of the vehicle speed and the roadway surface condition on the random dynamic loads of the wheels are analyzed. The results will be helpful for reducing the dynamic loads of the wheels and the damage to the road.
