摘要

基于达朗贝尔原理，在建立座椅悬架系统的虚平衡状态的基础上，推导出了系统的运动微分方程，得到了系统的传递函数。采用试验测定手段，得到了座椅悬架主要元件的力学性能及座椅传递特性，并通过试验结果验证理论模型的准确性。在此基础上，讨论各参数对悬架系统共振频率及幅值的影响，针对其结构参数对悬架系统进行了部分改进，可为座椅结构设计提供思路和解决方法。

Abstract

Based on D' Alembert's principle

the differential equation of the motion about the system was deduced

and the transfer function of the system was obtained by the basis of estabishing virtual equilibrium state of a seat suspension system. The mechanical properties of main components of seat suspension and seat transfer characteristies were obtained by means of experimental measurement. The accuracy of theoretical model was verified by the experimental results. On this basis

the influence of each parameter on resonance frequency and amplitude of the suspension system was discussed. The suspension system was partially improved according to structural parameters. The ideas and methods of this thesis can provide ideas and solutions for seat structure design.
