【摘要】：随着经济的发展和生活水平的提高,我国城镇居民拥有汽车的数量也不断增长,在我国人均土地占有率低的情况下,停车场和停车位的短缺问题已经变成限制影响我国居民日常生活水平的一个重要问题。考虑我国的国情,结合我国政府颁布的各项政策措施,大力建设推广立体停车设备,将会成为有效缓解我国城镇居民停车难现象的方法。随着计算机辅助设计(CAD)技术的飞速发展,以及工业4.0的提出,产品设计的智能化、自动化与参数化已经成为个机械行业产品的发展方向。为提高立体停车设备的设计开发效率,降低设计人员的工作量,从而降低设计生产成本,实现立体停车设备的智能化与自动化,本文以某升降横移式立体停车设备为对象,以SolidWorks三维设计软件以依托,以Access作为数据库管理手段,采用Visual Basic(VB)编程语言,进行立体停车设备CAD系统的开发研究。考虑到风载荷对立体停车设备安全性与稳定性的影响,本文首先对立体停车设备的风载安全性进行了分析,以三层三列升降横移式立体停车设备为例,分别选取其空载、满载以及顶层满载中间层空载的极端状态进行风载计算分析,并做虚拟仿真得出其风载薄弱环节,并专门对薄弱环节做不同的风载施加判断其风载破坏临界风速值。对立体停车设备的CAD系统开发,首先对升降横移式立体停车设备进行研究分析,建立零部件参数数据库,同时建立立体停车设备的零部件模型库,确定立体停车设备的成本核算方法与报价方法,利用VB语言设计人机交互界面,链接数据库和SolidWorks软件实现对立体停车设备模型的自动生成以及报价。本系统操作简单,界面直观简洁,应用便捷,对于技术人员相对紧张的立体停车设备企业具有极好的应用前景。
[Abstract]:With the development of economy and the improvement of living standard, the number of cars owned by urban residents in China is also increasing. Under the condition of low per capita land share in China, The shortage of parking lots and parking spaces has become an important problem affecting the daily living standards of Chinese residents. Considering the national conditions of our country and combining with the policies and measures promulgated by our government, it will be an effective method to alleviate the parking difficulty of urban residents in our country by vigorously constructing and popularizing the three-dimensional parking equipment. With the rapid development of computer aided design (CAD) technology and the proposal of industrial 4. 0, the intelligence, automation and parametrization of product design have become the development direction of machinery industry products. In order to improve the design and development efficiency of stereoscopic parking equipment, reduce the workload of designers, reduce the cost of design and production, and realize the intelligence and automation of stereoscopic parking equipment, this paper takes a lifting and transversely moving stereoscopic parking equipment as the object. Based on SolidWorks 3D design software, Access is used as database management means, and Visual Basic (VB) programming language is used to develop and study the CAD system of stereoscopic parking equipment. Considering the influence of wind load on the safety and stability of stereoscopic parking equipment, this paper first analyzes the wind load safety of stereoscopic parking equipment, and takes the three-story and three-row lifting and transversely moving stereoscopic parking equipment as an example to select its no-load respectively. The extreme state of full load and top layer full load is calculated and analyzed, and the weak link of wind load is obtained by virtual simulation, and the critical wind speed of wind load failure is judged by different wind load. In the development of CAD system of stereoscopic parking equipment, firstly, the lifting and transversely moving stereoscopic parking equipment is studied and analyzed, and the database of parts and components parameters is established, and the parts model library of stereoscopic parking equipment is established at the same time. The cost accounting method and quotation method of stereoscopic parking equipment are determined. The human-computer interaction interface is designed by VB language, and the automatic generation and quotation of stereoscopic parking equipment model are realized by linking database and SolidWorks software. The system has the advantages of simple operation, intuitionistic and concise interface and convenient application. It has an excellent application prospect for the three-dimensional parking equipment enterprises where the technicians are relatively nervous.
