北京理工大学珠海学院 2020 届本科生毕业设计五十铃货运汽车升降尾板液压系统设计五十铃货运汽车升降尾板液压系统设计摘 要本文首先介绍了汽车尾板液压系统的研究背景和意义，通过了解市场和查阅各项数据与资料，整理出尾板液压系统的相关理论知识。基于汽车液压系统对货运汽车尾板液压系统进行了设计。通过对尾板的结构受力分析和车型的参数分析，得出了液压缸的受力情况和载荷，通过计算得出液压缸的流量，从而得出液压缸的尺寸大小并对其结构进行了设计。接着设计出了升降尾板液压系统，对液压控制回路进行动作分析，通过计算，选出液压系统中的液压泵、电机、液压阀原件体等型号。最终的完成尾板液压系统的设计。本文采用的尾板板形式为垂直升降尾板，能更大的节省了空间。关键词：五十铃货运汽车；升降尾板；液压系统设计北京理工大学珠海学院 2020 届本科生毕业设计Design of Hydraulic System for Lifting Tail Plate of Isuzu Motors Freight CarAbstractThis paper first introduces the research background and significance of automotive tail plate hydraulic system, through understanding the market and consult various data and data, sorted out the relevant theoretical knowledge of tail plate hydraulic system. Based on the automobile hydraulic system, the tail plate hydraulic system of freight car is designed. Through the structural stress analysis of the tail plate and the analysis of the vehicle parameters, the force and load of the hydraulic cylinder are obtained, the flow rate of the hydraulic cylinder is calculated, and the size of the hydraulic cylinder is obtained and its structure is designed. Then the design of the lifting tail plate hydraulic system, the hydraulic control loop for action analysis, through the calculation of the hydraulic system in the hydraulic pump, motor, hydraulic valve components and other models. The final completion of the tail plate hydraulic system design. In this paper, the form of tail plate is vertical lifting tail plate...
