【摘要】：近幾年來(lái)，隨著全國(guó)城市建設(shè)速度的加快，城市居民汽車(chē)保有量急劇增加，隨之而來(lái)的是交通擁擠現(xiàn)象嚴(yán)重，居民小區(qū)周?chē)ⅠR路邊亂停車(chē)現(xiàn)象也日益嚴(yán)峻，各大城市停車(chē)問(wèn)題已經(jīng)非常突出。此時(shí)，立體車(chē)庫(kù)的大量投入使用，可以有效解決雜亂無(wú)章的停車(chē)問(wèn)題。但是目前的情況就是多數(shù)大型立體車(chē)庫(kù)一直在中國(guó)各大城市難以推廣，究其原因，還是由于投入成本太高，利用率過(guò)低、車(chē)庫(kù)停車(chē)費(fèi)用較高，加之相關(guān)部門(mén)為了自己的收益，而隨意在馬路邊規(guī)劃臨時(shí)停車(chē)位。而本課題的立體車(chē)庫(kù)本身所具有的開(kāi)發(fā)難度小、模塊化程度較高等優(yōu)點(diǎn)，使得本課題所研究的立體車(chē)庫(kù)在大城市中更容易推廣使用。 本文主要是針對(duì)實(shí)驗(yàn)室課題研發(fā)的立體車(chē)庫(kù)，設(shè)計(jì)了一整套驅(qū)動(dòng)與傳動(dòng)系統(tǒng)以及電子轉(zhuǎn)換裝置，包括以下幾個(gè)方面：一、對(duì)立體車(chē)庫(kù)的國(guó)內(nèi)外現(xiàn)狀、本課題研究的目的和意義、將要完成的內(nèi)容進(jìn)行介紹；二、首先對(duì)立體車(chē)庫(kù)的整體框架結(jié)構(gòu)和存取車(chē)工作流程進(jìn)行介紹，，其次確定驅(qū)動(dòng)與傳動(dòng)系統(tǒng)整體方案，最后對(duì)電子轉(zhuǎn)換裝置方案的確定。三、對(duì)立體車(chē)庫(kù)驅(qū)動(dòng)與傳動(dòng)系統(tǒng)進(jìn)行詳細(xì)設(shè)計(jì)，包括立體車(chē)庫(kù)所受載荷類(lèi)型及計(jì)算方法，電機(jī)、制動(dòng)器及聯(lián)軸器的選型和計(jì)算，曳引輪和對(duì)重的設(shè)計(jì)。四、立體車(chē)庫(kù)電子轉(zhuǎn)換裝置的機(jī)械結(jié)構(gòu)設(shè)計(jì)，主要是與上位機(jī)和PLC之間邏輯關(guān)系的確定，電子轉(zhuǎn)換裝置的工作原理，其中關(guān)鍵部件圓柱凸輪機(jī)構(gòu)各種參數(shù)的選擇及推程計(jì)算，以及在Pro/E中三維建模和裝配，然后導(dǎo)入ADAMS里面添加約束建立虛擬樣機(jī)，之后再進(jìn)行運(yùn)動(dòng)學(xué)的仿真。五、立體車(chē)庫(kù)電子轉(zhuǎn)換機(jī)構(gòu)硬件電路的設(shè)計(jì)。這部分主要是對(duì)各個(gè)硬件電路（包括最小系統(tǒng)電路、控制電路、驅(qū)動(dòng)電路等）的設(shè)計(jì)，然后是電子轉(zhuǎn)換機(jī)構(gòu)與PLC之間串口通信模塊的設(shè)計(jì)，最后再進(jìn)行電路的仿真以及搭載實(shí)物平臺(tái)進(jìn)行驗(yàn)證。六、對(duì)立體車(chē)庫(kù)可靠性的設(shè)計(jì)，主要是對(duì)電子轉(zhuǎn)換裝置中的圓柱凸輪機(jī)構(gòu)進(jìn)行可靠性分析，包括凸輪與滾子之間的接觸力校核以及滾子自身的動(dòng)等價(jià)載荷的計(jì)算。 本文在對(duì)驅(qū)動(dòng)與傳動(dòng)系統(tǒng)的設(shè)計(jì)研究基礎(chǔ)上，改進(jìn)了傳統(tǒng)的立體車(chē)庫(kù)傳動(dòng)系統(tǒng)，改由一臺(tái)電機(jī)選擇性的為多列載車(chē)單元模塊提供動(dòng)力的設(shè)計(jì)方法，不僅使得驅(qū)動(dòng)與傳動(dòng)系統(tǒng)的結(jié)構(gòu)布局緊湊，大大節(jié)省了空間，減少了驅(qū)動(dòng)電機(jī)的數(shù)目，降低了成本。同時(shí)，電子轉(zhuǎn)換機(jī)構(gòu)中采取使用圓柱凸輪機(jī)構(gòu)來(lái)帶動(dòng)滑移齒輪的嚙合與分離，通過(guò)采用單片機(jī)控制步進(jìn)電機(jī)來(lái)帶動(dòng)圓柱凸輪機(jī)構(gòu)的旋轉(zhuǎn)角度，從而達(dá)到精確控制的目的。
[Abstract]:In recent years, with the acceleration of urban construction throughout the country, the number of cars owned by urban residents has increased sharply, followed by a serious traffic jam, and the phenomenon of random parking around residential areas and on the side of roads is becoming increasingly serious.The problem of parking in major cities has become very serious.At this time, the use of a large number of three-dimensional garage, can effectively solve the problem of random parking.However, the current situation is that most large stereoscopic garages have been difficult to popularize in major cities in China. The reason is that the input costs are too high, the utilization rate is too low, the parking costs of the garages are high, and the relevant departments are making their own profits.And plan temporary parking spaces at random on the side of the road.The development of the stereoscopic garage has the advantages of low difficulty and high modularization, which makes it easier to popularize and use the stereoscopic garage in the big city.In this paper, a whole set of drive and transmission system and electronic conversion device are designed for the research and development of stereoscopic garage in laboratory, including the following aspects: first, the purpose and significance of the research on the status quo of the stereoscopic garage at home and abroad.The contents to be completed are introduced. Firstly, the whole frame structure and the work flow of the access car are introduced. Secondly, the whole scheme of the drive and transmission system is determined. Finally, the scheme of the electronic conversion device is determined.Thirdly, the drive and transmission system of the stereoscopic garage is designed in detail, including the load type and calculation method, the selection and calculation of motor, brake and coupling, the design of traction wheel and counterweight.Fourthly, the mechanical structure design of the electronic conversion device of the stereoscopic garage is mainly about the determination of the logical relationship with the upper computer and the PLC, the working principle of the electronic conversion device, the selection of various parameters of the cylindrical cam mechanism and the calculation of the push range.And 3D modeling and assembly in Pro/E, then importing constraints into ADAMS to build virtual prototype, and then kinematics simulation.Fifth, the design of the hardware circuit of the electronic conversion mechanism of the stereoscopic garage.This part is mainly about the design of each hardware circuit (including minimum system circuit, control circuit, drive circuit, etc.), and then the design of serial communication module between electronic conversion mechanism and PLC.At last, the simulation of the circuit and the verification of the physical platform are carried out.Sixthly, the reliability design of the stereo garage is mainly about the reliability analysis of the cylindrical cam mechanism in the electronic conversion device, including the checking of the contact force between the cam and the roller and the calculation of the dynamic equivalent load of the roller itself.Based on the design and research of drive and transmission system, this paper improves the traditional three-dimensional garage transmission system, and changes the design method of one motor selectively to provide power for the multi-column vehicle unit module.It not only makes the structure of drive and transmission system compact, but also saves space, reduces the number of drive motors and reduces the cost.At the same time, the cylindrical cam mechanism is used to drive the meshing and separation of the slip gear in the electronic conversion mechanism, and the rotation angle of the cylindrical cam mechanism is driven by the step motor controlled by the single chip microcomputer, so as to achieve the purpose of accurate control.
