【摘要】：随着国内经济的蓬勃发展,汽车行业的兴起,私有轿车更加普及化。然而由于土地资源的紧缺,城市交通基础设施建设的滞后,交通拥堵、停车难等所引发的一系列社会问题亦成为制约城市发展的不利因素。由此立体停车库运用而生,并凭借其占地面积小,库容量大,自动化程度高等多方面的优点得到了迅速发展。本文在北京鑫华源机械制造有限责任公司实习和调研的基础上,以河北高碑店项目所设计的三层十六车位升降横移式立体车库为研究对象。文章阐述了国内外立体车库近年来的发展、类型及其特点。基于概率统计原理,对调研搜集的400种轿车长、宽、高及载荷参数进行了分析,所得车辆参数为立体车库结构参数的设计提供了依据。针对升降横移式立体车库主体结构及工作原理进行了概述,对其钢结构骨架主要构件进行了受力分析、稳定性校核,并利用ANSYS进行了有限元分析。在保证钢结构强度、刚度性的基础上,对钢结构系统进行了合理优化,可节省25.05%钢结构,从而降低了立体车库的制造成本,避免过多的浪费。立体停车库较好的缓解了停车难的问题,但同时又不得不面对长时间存取车等待问题。为提高立体车库的存取效率,减少存取时间,降低顾客等待几率,以排队论理论为基础,建立了以平均存取时间为目标函数存车优先、取车优先、原地待命、交叉存取四种调度策略下的数学模型。通过对实例四种不同策略下排队模型所得主要参数指标对比分析,得到排队系统最优调度策略。
[Abstract]:With the vigorous development of the domestic economy, the rise of the automobile industry, the private car is more popular. However, due to the shortage of land resources, city infrastructure construction lag, traffic congestion, a series of social problems caused by parking has become unfavorable factors restricting the development of the city. The parking and use of health, and with its small footprint, large storage capacity, has the advantages of high degree of automation in many aspects has been developing rapidly. This paper internship in Beijing xinhuayuan Machinery Manufacturing Co Ltd and research, Hebei Gaobeidian project three sixteen parking spaces in the up-down and translation stereo garage as the research object. The article elaborated the domestic and foreign in recent years, the development of three-dimensional garage, the types and characteristics of probability and statistics. Based on the principle of 400 kinds of car research to collect the long, wide, and high load parameters were analyzed, the Provide the basis for the design of vehicle parameters for stereo garage structure parameters. The up-down and translation stereo garage the main structure and working principle are introduced, the main component of the steel structure framework for stress analysis, stability checking, and finite element analysis using ANSYS. In ensuring the strength of steel structure, foundation stiffness on the reasonable optimization of steel structure system, can save 25.05% of the steel structure, thereby reducing the manufacturing cost of stereo garage, to avoid excessive waste. Parking solve the parking problem, but also have to face a long time to access the car waiting for problem. In order to improve the access efficiency of stereo garage the reduced access time, reduce customer waiting probability, based on queuing theory, established by the average access time as the objective function for car parking priority, priority, on standby, cross access four The mathematical model of the scheduling strategy is analyzed. Through the comparative analysis of the main parameters of the queuing model under four different strategies, the optimal scheduling policy of the queuing system is obtained.
