But for a long time, many modern industrialized country show little concern on the current transportation problem, they neglect to equip machinery for the disable to login in or out the bus. There exists some unharmonious problems in the phenomenon, it may cause the apartment for the public concentration and the reduction on the human concern. Equipping special door for the disable in the general distribution for the bus, and equipping elevating system for the disable on the basic of the door have advantages. For these advantages,safety,easy-operating,volum saving, high efficient, good package(hydraulic power unit),long using time and low cost is the prior concern for the manufacture and the public. These advantages greatly show the degree of progress from social technology to the human concern.To realize the no-disturb for the disable to login and the special trained servant to operate this set of machinery，we should first talk deeply about the feasibility of this machinery. Through the analysis on the power unit, the analysis on the feasibility ,safety, movement evaluating and the analysis of using afterwards, we establish the general structure, and we can also choose the suitable structure according to the system. Therefore, we first study the choose on the structure. Based on the knowledge, some file on the internet and the current state of the relevant machineries home and aboard, we have performed up-to-date study and design a set of elevating system for the disable to login on bus. This system uses hydraulic locking-current as the power unit and uses sole machinery for elevating. The paper begins with the argument on the general structure, and neatly introduce the structure analysis, design and calculating steps, and also performed some general structure design, power conducting machinery design and evaluating etc.Its widely used in the public transportation for any disable people, ensuring them to login on and out the bus convinently,and fatherly shows our progress on human concern.Key words: on-bus elevating system for the disablers login， elevating plate，layout目錄1 前言-（1）2 系統(tǒng)開發(fā)方案說明2.1方案比較及選擇-（8）2.2需要進行的任務-（10）3 總體設計3.1主要桿件的運動校核受力分析以及強度校核-（11）3.1.1運動校核-（11）3.1.2受力分析及機構結構分析-（12）3.2液壓系統(tǒng)總成計算- （15）3.3其他一些相關的問題-（22）3.3.1機構的動作順序及其要求借助外力完成的問題-（22）致謝-（23）參考文獻-（24）共 頁 第 頁
