Abstract

A two-DOF dynamic equation with cubic nonlinear stiffness was established. The response of the system to the four kinds of path spectrums which are cement road, washboard road, pebble road and fishscale pits road is obtained by Runge-Kutta method and the vertical vibration serviceability is obtained by simulation calculation. The curves of vibration serviceability-damping coefficient under the four kinds excitations of path spectrums are also obtained which supply theoretical basis for dynamic design of the tractor.
