摘要

为提高工程车辆座椅的低频隔振能力，及适应驾驶员身高、体重参数的差异性，设计了一种集成身高和体重调节功能的座椅非线性悬架，建立了核心设计参数与其力-位移特性间的数学模型，确定了主要设计参数。基于ADAMS软件仿真验证了座椅悬架的力-位移特性、调整功能，并制造了物理样机进行了试验验证。结果表明，所设计的悬架具有较好的非线性特性，高度、体重参数可调，且参数的调整不影响悬架的低频隔振能力。

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.
