【摘要】 本文首先介绍了轻轨交通发展概况,分析了独轨交通的走行特点,提出了研制巡检车的必要性和撰写本文的目的及意义。巡检车属于较复杂的行走机械产品,文中从系统的观点出发对巡检车的功能要求进行了较为详细的分析。通过对各种具体方案的对比分析和权衡各方案的优缺点,提出了巡检车的最终驱动方案、用电方案,并进行了详细的计算和分析,满足了所设计车辆的功能要求。文中通过分析独轨车辆的走行特点,从巡检车的主要部分构成出发,完成了对驱动系统、走行装置、车体、车厢等主体部分的选择、计算和设计,同时应用人机工程学方法完成了对驾驶控制台的尺寸和布局设计。文中应用计算机辅助设计方法对巡检车车体、车厢进行了建模分析,完成了其可视化、参数化车架与车身设计,并对走行装置、车架、车厢进行虚拟装配。采用计算机辅助设计方法不仅修改方便,管理容易,缩短了产品研发时间,同时还可大大降低了开发成本。另外,根据轮胎力学、汽车动力学方面的知识并结合独轨车辆行驶特点,对车辆在不同的行驶工况下所受到的阻力进行了详尽的分析并列出了行驶阻力表,为车辆的驱动计算提供了基础数据。探讨了独轨车辆沿导向轨道梁匀速直线前进时,车体构架及轮胎所产生的横摆、侧滚和摇头运动,并根据刚体运动学原理,在忽略垂直载荷的变化对走行轮胎各向刚度特性的影响下,建立了轮胎的三自由度方程,该动力方程反映了巡检车的横向运动特征,为研究巡检车在轨道梁上行驶稳定性奠定了基础。文中最后部分是对论文所研究工作的总结。更多还原

【Abstract】 Firstly, the general situation of the development of Light Rail transport was introduced in this paper, then the need to manufacture this vehicle and the purpose and significance of writing this dissertation were presented.This inspection vehicle belongs to the complex mechanical products. From the systematic point of view, the overall design scheme of this vehicle were given in detailed through functional analysis and the principal functional requirements of the vehicle were clarified. Then, after the comparison of the specific schema for each functional requirements and weighing the advantages and disadvantages of the various schemes, the final driving scheme and electricity scheme were obtained. Moreover, the detailed calculations and the choosing of main devices for constituting the scheme were completed in this dissertation.Considered the principal components of this vehicle, calculation and design of the drive system, moving devices, vehicle body and the carriage were completed in this paper. Also the ergonomics had been applied to the design of the driving console. The vehicle body and the carriage were modeled by using UG software for its visualized and parametric design traits. And it because of its virtual assembly and easy to modify and manage that the product development time was shorten and development cost was reduced dramatically. In addition, according to tires mechanics, the vehicle dynamics knowledge and the unique moving traits of the straddle-type monorail vehicle, the resistance analysis under different driving conditions was calculated detailedly in form of Table. The resistance data Table has provided basic data for calculating the vehicle drive system.The dissertation has explored and studied the lateral, roll and yaw movement of car body and tires. And the dymamical equation of this straddle type monorail vehicle is esTablelished by adopting linearized tire model according to rigid body kinematic theory under disregard of effects that the changes of vertical load have to the rigidness trait of the running tires. And this equation reflects the transverse movement of the vehicle and has laid the foundation to study the traffic sTableility of this straddle-type monorail vehicle. The final part is the conclusion of this dissertation.更多还原
