【正文】 Automatic door Pneumatic system Design and motion Simulation Abstract The automatic door is the automation in the process of a typical representative, this design is the use of learned knowledge, bined with the actual needs and make a study of. This paper focuses on the automatic door opening and closing ’s pneumatic system was designed, and its motion simulation. Through analyzed the automatic doors function and structure to identified the automatic pneumatic control system diagram, and piled the PLC control procedures, to achieve the automatic door working process. On this basis, using Pro / E software for automatic door structure of 3D modeling, virtual assembly and motion simulation of the working process.

在現(xiàn)代社會(huì)生活中，人們的生活節(jié)奏越來越快，對(duì)效率的要求也越來越高，這體現(xiàn)在各個(gè)方面，而自動(dòng)門控制系統(tǒng)正是基于這個(gè)社會(huì)背景產(chǎn)生的，自動(dòng)門控制系統(tǒng)是一個(gè)應(yīng)用非常廣泛的設(shè)備，已廣泛應(yīng)用于酒店、銀行、超市、停車場(chǎng)或公共建筑等地方。 基于可編程控制器（ PLC）控制的自動(dòng)門由于故障率低、可靠性高、維修調(diào)試方便等優(yōu)點(diǎn)，因而得到廣泛的應(yīng)用。以實(shí)現(xiàn)該功能，因?yàn)闅鈮涸谏钪蟹浅Ｈ菀踪徺I，且價(jià)格適宜，同時(shí)也便于維護(hù)，非常適合廣泛生產(chǎn)應(yīng)用，并且可以就地取材 ——空氣。從新產(chǎn)品開發(fā)能力和質(zhì)量穩(wěn)定性方面還不具備和進(jìn)口產(chǎn) 品競(jìng)爭(zhēng)的實(shí)力。 (4)自動(dòng)門產(chǎn)品的種類呈多樣化趨勢(shì)，加之 自動(dòng)門產(chǎn)品往往是開發(fā)商而非最終用戶在選擇產(chǎn)品，所以價(jià)格因素加劇了市場(chǎng)競(jìng)爭(zhēng)。 (2)易維護(hù)：在設(shè)計(jì)的過程中采取多種措施，以盡量減少在使用過程中的維護(hù)工作。 3
