【Abstract】 The dynamical characteristics of a suspension system of agricultural transporters and the effects of a hydraulic shock absorber on these properties were studied. Effects of a gas column in the shock absorber of agricultural transporters on the system performance and variation laws of a gas column elastic rigidity during drawing and pressing processes were analyzed and confirmed. So the dynamics of the suspension may be determined by the damping factor of the hydraulic shock absorber or directly obtained by means of the test which simulates the practical suspension performance of an agricultural transporter. Since nonlinear damping property of the hydraulic shock absorber the reuslt from the test method is better than that from the damping factor.更多还原
