摘要

摘要: 以某重卡汽车阻尼多级可调的电子控制空气悬架系统为研究对象,基于Matlab/Simulink模块分别建立1/4车辆悬架系统模型、理想天棚和实际天棚控制模型,给出阻尼可调的天棚控制器设计方法。该方法分析车身加速度az、悬架动挠度fd和轮胎动载荷tl随阻尼系数的变化规律,对该车辆悬架系统的平顺性(az,fd)和道路友好性(tl)目标进行加权优化处理,得到不同控制策略下使悬架获得最优综合性能的悬架阻尼系数。仿真结果表明:采用优化后的天棚阻尼控制器能够有效改善车辆平顺性和道路友好性。

Abstract: A quarter heavy truck dynamic model assembled with the electronically controlled air suspension with stepped adjustable damping is studied, and the ideal and actual controller models of the air suspension are presented based on Matlab/Simulink software, then a method of designing skyhook controller is proposed. In this method, variation laws of the body acceleration denoted as az, the suspension dynamic deflection denoted as fd and the tire dynamic load denoted as tl due to the transfer of suspension damping are analyzed. Moreover, ride comfort (az,fd) and road friendliness (tl) indexes of this suspension control model are weighted to create a new comprehensive index, according to which the best damping coefficient under different control strategies can be obtained. Finally, the simulation results indicate that the ride comfort and road friendliness of the heavy truck can be obviously and efficiently improved by using the optimized skyhook damping controller.
