摩托车悬架系统的仿真设计

摘要

建立摩托车五自由度的动力学模型，推导了计算公式，编制了悬架系统的仿真结构框图，运用MATLAB＼SIMULINK软件对摩托车悬架进行仿真计算.给出悬架系统结构参数在不同路面条件下对座椅加速度、车身动载荷、悬架动挠度的影响.%This paper constructs five freedoms dynamics model of the motorcycle and deduces its formulation . It presents the chart of the simulation structure of the suspension system and uses the MATLAB＼SIMULATION to simulate the motorcycle suspension and presents the influence of the suspension parameter on the seat acceleration , body dynamic load and dynamic deflection of suspension under different spectrums of road surface roughness.
