摘要

在过去,汽车主动悬架系统是利用静压、电、磁和磁流变(MR)技术来控制道路振动和车辆动力学,从而提高乘坐舒适性和车辆性能。但是,没有为重型设备、卡车和非公路车辆开发这样的系统。例如,农用拖拉机仍然配备了最小的悬挂系统,给司机带来了不适和健康问题。由于这些车辆的巨大重量导致的高悬架载荷是一个挑战,因为需要高力来实现有效的主动悬架控制。本文提出了一种经实验验证的静压磁流变离合器驱动作动器系统的可行性研究。本文的范围是评估执行器的初步性能,为未来的振动控制做准备。液压系统允许执行器远离重型车辆的车轮或驾驶室,并方便地放置在车辆的悬挂框架上。该设计包括两个MR离合器驱动在一个对抗配置推和拉的末端执行器。在实验室样机上进行的实验表明,离合器的低惯性特性允许20 Hz的高阻塞输出力带宽,峰值输出力超过15 kN。

Design and Experimental Assessment of a Vibration Control System Driven by Low Inertia Hydrostatic Magnetorheological Actuators for Heavy Equipment
Active suspension systems for automotive vehicles were developed in the past using hydrostatic, electric, magnetic and magnetorheological (MR) technologies to control road vibrations and vehicle dynamics and thus improve ride comfort and vehicle performance. However, no such systems were developed for heavy equipment, trucks and off-highway vehicles. For instance, agricultural tractors are still equipped with minimal suspension systems causing discomfort and health problems to drivers. The high suspension loads due to the massive weight of these vehicles are a challenge since high forces are needed to achieve efficient active suspension control. This paper presents an experimentally validated feasibility study of a hydrostatic, MR clutch-driven system of actuators. The scope of this paper is to evaluate the preliminary performance of the actuator for future vibration control. The hydraulic system allows the actuators to be remotely located from the wheels or cabin of the heavy vehicle and conveniently placed on the vehicle’s suspended frame. The design includes two MR clutches driven in an antagonistic configuration to push and pull on the end effector. Experiments on a laboratory prototype show that the low-inertia characteristics of the clutches allow a high blocked-output force bandwidth of 20 Hz with peak output forces exceeding 15 kN.
