    Abstract
  • In order to analyze the dynamic load character of vehicle running on uneven pavement, the surface of pavement was simulated by using sinusoid according to the evenness measure result of Xi-Bao freeway, a four-free-degree model of vehicle vibration was set when vehicle lean factor and tire damping were considered, a calculating method of vehicle dynamic load was presented through analyzing and solving vehicle vibration problem by using modal theory and programming calculation, when the left and right wheels of vehicle were not impelled at the same time, and vehicles ran at different speeds on different pavement models with different wavelengthes and amplitudes.Calculation result indicates that vehicle dynamic load caused by waveform pavement shows waveform distribution in longitudinal direction, vehicle running on uneven pavement may produce great dynamic load, and the maximum coefficient of dynamic load is above 2.0.
