摘要
隨著人類社會(huì)的不斷進(jìn)步和經(jīng)濟(jì)的飛速發(fā)展 ,城市車輛日漸增多, 人們的生存空間卻越來(lái)越小, 城市市區(qū)尤其是中心商業(yè)區(qū)停車難的問(wèn)題已成為制約城市發(fā)展的一大難題 。由于人們?cè)缙趯?duì)此認(rèn)識(shí)不足，在城市規(guī)劃時(shí)對(duì)停車設(shè)施考慮不夠，多為平面式停車場(chǎng)，而這顯然不能滿足人們的停車需要，造成了目前停車設(shè)施嚴(yán)重缺失的局面。立體車庫(kù)的出現(xiàn)，為解決這一難題帶來(lái)了希望，將地面停車向空間發(fā)展，形成立體停車模式，已經(jīng)成為緩解城市“停車難”的重要途徑之一。
而液壓系統(tǒng)與傳統(tǒng)機(jī)械系統(tǒng)相比，由于具有重量輕、體積小、運(yùn)動(dòng)慣性小、反應(yīng)速度快、工作平穩(wěn)、操縱控制方便、可實(shí)現(xiàn)大范圍的無(wú)級(jí)調(diào)速、可自動(dòng)實(shí)現(xiàn)過(guò)載保護(hù)、當(dāng)采用電液聯(lián)合控制后，不僅可實(shí)現(xiàn)更高程度的自動(dòng)控制過(guò)程，而且可以實(shí)現(xiàn)遙控等優(yōu)點(diǎn)，成為立體車庫(kù)傳動(dòng)系統(tǒng)的首選，本設(shè)計(jì)的主要內(nèi)容包括立體停車庫(kù)液壓系統(tǒng)原理設(shè)計(jì)，液壓系統(tǒng)動(dòng)作確定等。通過(guò)液壓馬達(dá)實(shí)現(xiàn)載車平臺(tái)的平移，液壓缸實(shí)現(xiàn)載車平臺(tái)的升降，80秒內(nèi)會(huì)完成一輛汽車的存放。實(shí)現(xiàn)立體車庫(kù)占用空間少，存取方便的功能。

Abstract
With the rapid development of economy and the continuous progress of human society, the increasing number of vehicles in the city, the people's living space is getting smaller and smaller, urban areas especially center business area, parking difficult issues has become a restricting the urban development is a major problem. Due to the early people knows inadequacy, in the urban planning of parking facilities consideration is not enough, mostly flat parking lot, which obviously can not meet the people's demands of parking, resulting in the current situation of serious lack of parking facilities. Stereo garage, in order to solve this problem brings hope, the ground parking space for development to form stereo parking mode, has become the urban parking difficult "one of the important ways to alleviate.
And compared with traditional mechanical system and hydraulic system, because of its light weight, small volume, small inertia, fast response speed, stable work, manipulation is easy to control and can achieve a wide range of stepless speed regulation, automatic overload protection, when the electrical and hydraulic control, not only can achieve a higher degree of automatic process control and remote control and other advantages become stereo garage transmission system of choice, the design of the main content including tridimensional parking garage design principles of the hydraulic system, hydraulic system action. Through the hydraulic motor to achieve the vehicle platform shift, the hydraulic cylinder to achieve the vehicle lift, 80 seconds will complete a car storage. The function of realizing the space of the stereo garage is less, and the access is convenient..
Key words: Parking garage，Hydraulic system，Principle design
