摘　　要：分析了农用运输车的行驶振动特性，应用自适应控制理论，建立了具有半主动悬架农用运输车的数学模型和控制模型，进行了半主动悬架和被动悬架振动响应的计算机仿真。结果表明：具有半主动悬架的车辆，振动加速度得到明显衰减。お quartercar model of the agricultural vehicle is used for comparing the ride performance limits of passive suspensions and semiactive suspensions based on the adaptive control theory in this paper. The response of the vehicle to random road inputs is analyzed by treating the road disturbance as a whitenoise velocity input. A mathematical model and a control model of semiactive suspension to random road disturbances are derived and the vibration response of the passive and semiactive suspensions is simulated. The results show semiactive suspensions for vehicles can reduce vibration effectively. The performance of semiactive suspensions with passive elements is found to be superior to the corresponding passive suspension system.
