Structural Optimization Of Up-down And Translation Stereo Garage And Analysis Of Its Control Strategies

Mechanical parking system is the storage which is used for automatic parking and scientific storage of kinds of automobile. As the quantity of urban automobile has increased continuously in nowadays, the hard-to-park problem has become a common phenomenon. Mechanical stereo garage can use land resource sufficiently and bring space advantage into play, and maximize the number of parking cars. It has become an important way for static traffic problem of cities. The issue studies the typic mechanical parking system which named up-down and translation stereo garage ,and regards of the two factors of cost of manufacture and operational efficiency synthetically, and analyses and optimizes the structure and the control strategies of the garage.On the basis of investigation on current situation and developing trend of garage in domestic and abroad, we choose three-layer and four-formulistic garage structure as the research model. The paper simply introduces main structure and characteristics of garage and also gives a short introduction to its control system. The finite element analysis of steel structure of garage is utilized according to the operation principle of up-down and translation stereo garage, In order to guarantee the security of garage, it is checked according to the strength theory. Based on the finite element analysis ,reasonable optimization of steel structure of garage is performed. The weight of steel structure of garage is reduced by 14% or so and the manufacturing cost is reduced.Recent research on garage control is to improve work efficiency of the garage by rising the speed. But it depends on the increasing of energy consumption, and it makes the working life of the garage shorter. The paper emphatically analyzes the parking queue model of garage and control strategies. Through deep research on queuing theory of operation research , M/M/1/N/∞queuing theory is applied on garage control to optimize analysis on the strategies. We choose staying await orders strategy as the main control strategy aided with parking (taking) cars priority strategy at the rush hours. It can effectively promote the work efficiency of the garage and can reduce the loss in energy consumption, reaching high economic values. And it is also a good attempt at the research style of multi-crossed disciplines by introducing the queuing theory and control strategy into stereo garage control.
