PAGE PAGE 36 基于人脸识别的立体车库-结构分析 摘 要 针对城市停车困难的问题，提出用基于人脸识别的立体车库来改善此类问题。本文主要是垂直循环立体车库的机械结构分析，对其基本原理和机械结构进行学习，对核心部位进行分析和创新。论文主要研究以下内容： 对垂直循环立体车库用SolidWorks进行三维建模和运动仿真。通过simulation对老式载车板进行有限元分析，提出一种对结构加梁的载车板设计方法，用SolidWorks对载车板建模及simulation有限元分析证明其性能提升，且分析同质量下不同轴距的轿车在载车板上呈现不同的受力情况。总结出，同质量下车轴距越长，对载车板等效应力越小，形变越小。在提升系统研究中，对老式链传动结构存在的问题进行分析，在其基础上设计出一种拔叉链轮结构，通过SolidWorks进行建模，阐述其设计原理。对提升链板做simulation有限元分析后，进行算例优化，优化后性能提升。对导轨进行完善，在只限制X轴方向位移的基础上，改变滚子轴承和轨道的宽度，得到X轴和Y轴都起到限制的导轨结构。对设置参数后的载车吊篮运转做干涉检测，无发生碰撞，证明设置的数据具有一定参考价值。 关键词：垂直循环立体车库；SolidWorks；simulation有限元分析；载车板；提升链板 Stereo garage-structure analysis based on face recognition Abstract In view of the difficulty of parking in cities, a three-dimensional garage based on face recognition is proposed to improve such problems. This article is mainly about the mechanical structure analysis of the vertical circulation three-dimensional garage, study its basic principles and mechanical structure, and analyze and innovate the core parts. The thesis mainly studies the following contents: Three-dimensional modeling and motion simulation of SolidWorks for vertical circulation solid garage. Through the finite element analysis of the old vehicle carrier plate through simulation, a design method of the vehicle carrier plate with structural beams is proposed. SolidWorks is used to model the vehicle carrier plate and the finite element analysis of the simulation proves that its performance is improved. Cars with a coaxial distance present different stress conditions on the load board. It is concluded that the longer the wheelbase of the vehicle with the same mass, the smaller the equivalent stress on the vehicle plate and the smaller the deformation. In the study of the lifting system, the existing problems of the old chain transmission structure were analyzed, and a fork sprocket structure was designed on the basis of it. Modeling was carried out through SolidWorks to explain its design principles. After the simulation finite element analysi
