摘要/Abstract

摘要： 线性座椅悬架低频隔振能力差,为提高非公路车辆的振动舒适性,基于球面滚子机构设计了座椅非线性悬架,建立了主要设计参数与其力-位移特性间关系的数学模型,进而确定了悬架的主要设计参数。基于ADAMS软件和试验方法,测试了悬架的力-位移特性和振动传递率特性。结果表明:所设计的悬架具有高静态刚度和低动态刚度,最低的隔振频率低于传统的线性座椅悬架。但是,悬架的内摩擦对其低频隔振性能影响较大,需要关注。

Abstract: Linear seat suspension has poor isolation ability of low frequency vibration. To improve the low frequency vibration isolation performance of off-road vehicle seat, a nonlinear seat suspension is designed based on spherical roller mechanism. The quantitative relationship between the main design parameters and the force-displacement characteristics is established, and then the main parameters are identified. Based on ADAMS method and test, the force-displacement characteristic and isolation performance of the nonlinear seat suspension are tested. Results show that the designed suspension has high static stiffness and low dynamic stiffness characteristics, and the lowest isolation frequency is lower than that of traditional linear seat suspension. However, the internal friction can affect low-frequency vibration isolation, to which attention should be paid in the suspension design.

Key words: vehicle engineering, seat suspension, nonlinear suspension, low-frequency vibration isolation
