Abstract

In order to improve the low-frequency vibration isolation capability of engineering vehicle seats and adapt to the differences in driver height and weight parameters, a nonlinear seat suspension with integrated height and weight adjustment functions was designed. A mathematical model was established between the core design parameters and their force displacement characteristics, and the main design parameters were determined. Based on ADAMS software simulation, the force displacement characteristics and adjustment function of the seat suspension were verified, and a physical prototype was manufactured for experimental verification. The results show that the designed suspension has good nonlinear characteristics, with adjustable height and weight parameters, and the adjustment of parameters does not affect the low-frequency vibration isolation ability of the suspension.
