| 摘要自动稳定杆系统能在车辆产生侧倾趋势时给车辆快速施加反侧倾力矩，减小车身侧倾角和侧倾角速度，并增大独立悬架的轮胎法向力，从而改善车轮与路面的附着状况等。液压系统为自动稳定杆的关键部件之一，本文将针对12款路虎极光，进行自动稳定杆液压系统的开发研究。 首先针对该车型进行自动稳定杆结构设计。在原有横向稳定杆的前提下，对其结构进行改进，加入液压系统执行元件，得到新的自动稳定杆机构。并对自动稳定杆系统在各种行驶要求下进行工况分析，为液压系统设计计算打下基础。19718 根据自动稳定杆系统的性能要求和空间大小以及控制的条件制约等要求，分析了自动稳定杆液压系统设计要求和液压系统工况，确定了液压系统方案和主要参数，拟定了能够实现需要功能的液压系统原理图，详细地说明了自动稳杆液压系统的设计计算过程并对其进行验算。 给出各关键部件的详细设计过程，并绘制装配图，建立三文模型 关键词 稳定杆 液压系统 液压执行器 毕业论文设计说明书（论文）外文摘要 Title Active lateral stabilizer bar hydraulic actuator design Abstract Automatic stabilizer bar system can skew the trend in the vehicle when turning up the heat on vehicle rapid heeling moment, reduced body roll Angle and roll Angle speed, and increases the size of independent suspension tire normal force, thus improving the wheel and the road adhesion conditions and so on.One of key components of the hydraulic system for automatic stabilizer bar, this article will focus on 12 land rover aurora, for the development of automatic stabilizer bar hydraulic system research. First the model for automatic stabilizer bar structure design.On the premise of the original transverse stabilizer bar, its structure was improved, join the hydraulic system of actuators, get new automatic stabilizer bar mechanism.And the automatic stabilizer bar system as required by the various driving conditions analysis, lays the foundation for the hydraulic system design and calculation. According to the requirements of the automatic stabilizer bar system performance and the size of the space, and control the constraints such as requirements, design requirements for automatic stabilizer bar hydraulic system are analyzed and the working condition of hydraulic system, hydraulic system and the main parameters, and formulate the function of can achieve need hydraulic system schematic diagram, detailed description of the automatic stabilizing rod hydraulic system design and calculation process and calculation. Given all the key components of the design process in detail, and draw the assembly drawing, 3 d model is established Keywords Stabilizer bar The hydraulic system Hydraulic actuator 目 次 1绪论 2 1.1研究背景 2 1.2 自动稳定杆系统国内外发展概况 3 1.3 自动稳定杆液压系统 3 1.4 论文主要研究内容 4 2主动式稳定杆系统工况分析 6 2.1 主动稳定杆系统工作原理 6 2.2 自动稳定杆液压系统工况分析 8 2.3 本章小结 11 3 主动式稳定缸的液压系统设计 12 3.1 液压系统方案设计及主要参数确定 12 3.2 拟定液压系统原理图 22 3.3 液压元件选择及专用件设计 23 3.4 液压系统性能验算 26 3.5 本章小结 30 4. 液压缸详细设计 31 (责任编辑：qin) |
