Abstract：
Stereo garage 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 type 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.
On the basis of investigation on current situation and developing trend of garage in
domestic and abroad, we choose three-layer and three-formulistic garage structure as the
research model. According to the form of the dragging-forms of multi player up-down and
translation ear-base, it is made of three parts: part of ear-base structure 、 part of
driving-framework and part of control system. The paper simply introduces main structure
and characteristics of garage and also gives a short introduction to its control system. The
finite element reliability checking of steel structure of garage is utilized according to the
operation principle of up-down and translation stereo garage, the mechanics was used to
comprehensively analyze the up-down and translation stereo garage. Including intension of
the framework structure and axes, etc. The paper adopted PLC as control system in designing
the up-down and translation stereo garage, PLC software of OMRON company was used to
weave the program of control system, through debugging running. The result proved that
adopted PLC as control system is simple and easy to realize. The characteristic of stabilization,
credibility, speediness and high capability made the control system very perfection. In order
to satisfy using demand in design stereo garage, according to criterion of mechanical parking
systems-general safety requirement and the facts of the up-down and translation stereo garage
the Paper introduced some safety technique which was used in the up-down and translation
stereo garage. This can ensure absolute safety for Car and make the whole stereo garage
safety and running smooth.
