Abstract: This paper briefly describes the situation of parking and car pick-up difficulties in China, analyzes the advantages of the three-dimensional garage, determines the overall design scheme of the three-dimensional garage, and designs a convenient three-dimensional garage with comb-shaped car plate. Explain the functional operations of the convenient automated parking system to achieve efficient car storage and retrieval. Use finite element analysis methods to analyze and calculate the main components, determine their maximum stress, displacement, and distribution on the parts. Research shows that this convenient automated parking system has the advantages of safety, stability, simple operation, low cost, and strong practicality, making it very suitable for the actual conditions in China.
