摘 要 与传统的运输系统相比，防爆无轨胶轮车在运输的效率、范围、适用性以及安全性等方面占据绝对优势，而且能够很大程度降低运输过程中人力的投入，不仅提高工作效率还能减少成本开支，尤其是在我国煤矿开采过程中对安全性的要求逐渐提高，在未来的煤矿开采工作中，防爆无轨胶轮车将会成为各大开采公司的首选运输设备。针对矿下单巷道无轨胶轮车特点，根据企业提出的要求，对车辆总体结构、主要结构、液压转向系统和制动系统进行了设计，同时借助AMEsim高级建模仿真软件，对设计系统中的转向与制动模块进行设计仿真，为WC05-1000A双向车提供设计依据和参考。 首先，根据企业对WC05-1000A双向无轨胶轮车提出的要求，在结构上进行了改进更新，同时利用SolidWorks软件对双向防爆无轨胶轮车的总体结构和分部结构进行了三维建模，根据车辆在矿下需满足的参数工作条件，对液压转向系统和制动系统所需要的液压元件进行了计算选型。 其次，根据煤矿井下行驶时对车辆制动性能以及转向性能的要求，设计出符合该车要求的液压转向系统和制动系统；在应用机液一体化设计思路的引导下，让本系统实现了转向、制动、防爆、双向驾驶等功能；在高质量的国产通用液压元件的支持下，能够充分保证系统性能的可靠性，而且在后期生产上能够很大程度上降低设计成本。 最后，基于高级仿真软件AMEsim对整车转向系统和制动系统进行仿真分析，通过仿真分析，验证所设计系统满足矿用双向无轨胶轮车的转向和制动要求。

ABSTRACT Trackless rubber tired vehicle with reliable explosion-proof, high transport efficiency, wide application range, flexible, high traction, strong adaptability, and good safety, which can increase the efficiency and reduce the input compared with the traditional transport system. Furthermore, trackless rubber tired vehicle with reliable explosion-proof now become the first choice due to the higher requirements of safety production. The overall structure, major components, hydraulic steering system and brake system of the trackless rubber tired vehicle was designed according to characteristics of the vehicles and request of the company. Then, the steering and braking system were simulated based on the AMEsim, which would provide the reference and basis for the WC05-1000A bidirectional explosion-proof vehicle. Firstly, the 3D model of overall and branch structure for bidirectional explosion-proof trackless rubber tired vehicle were estabilished using SolidWorks software based on the requirement of two-way trackless vehicles of WC05-1000A., Then, the components in the hydraulic brake system and steering system were selected according to the parameters and working conditions. Secondly, Secondly, a suitable steering and braking system was designed according to the requirement of vehicle braking and steering characteristics at the coal mine, which including Steering, speed changing and braking. With the integration idea of machine and fluid, variable speed, explosion-proof, two-way driving of the system was realized. The reliable performance and low cost can be realized by using high quality hydraulic components. Additionally, the stability of the transmission conversion module can be ensured with the support of a two-way hydraulic control valve. Finally, the vehicle braking system and steering system were simulated and analyzed based on the AMEsim.The requirements of steering and braking are achieved by analysis.
