基于MATLAB的重型车辆提升桥空气悬架设计方法研究

为研究重型车辆提升桥空气悬架设计方法,基于Matlab/Simulink建立了半车四自由度非线性模型,仿真计算了车辆行驶时的车轮动载荷,采用道路损伤系数对重型车辆的道路友好性进行评价。结果表明:提升桥的使用能在相同载重量下有效减少车辆对路面的破坏;适当降低提升桥悬架刚度系数或增大悬架阻尼系数,可减小车辆道路损伤系数,提高车辆的道路友好性。

Research on Design Method of Lifting Axle Air Suspension of Heavy-duty Truck Based on Matlab

For studying design method of lifting axle air suspension for a heavy-duty truck,a nonlinear model of four degrees of freedom is built to simulate the dynamic response of vehicle axle load based on Matlab/Simulink,adopt road damage coefficient for evaluation the road friendliness of heavy-duty vehicle.The results show that:using lifting axle makes the damage on the road reduced effectively under the same load;appropriate to reduce lifting axle suspension stiffness coefficient or increase suspension damping ...
