内容简介：

黑龙江工程学院本科生毕业设计摘 要随着国内外汽车业的蓬勃发展，汽车维修行业也随之得到大力发展，汽车举升机是现代汽车维修作业中必不可少的设备，其中举升机的安全可靠性，使用方便是大家一直以来研究的重点。本设计主要围绕剪是举升机进行设计研究的。主要因为剪刀式举升机使用方便，占地空间较小，受到很多实力雄厚的特约维修站的欢迎，这也是未来举升机的发展方向。本文首先对剪刀式举升机的整体结构，各部件尺寸，运动形式进行确定，建立力学模型，并对每个举升臂进行受力分析，确定结构和选材的合理性。之后建立Pro/E与ANSYS的集成接口，将利用Pro/E三维建模后的主要部件导入有限元软件ANSYS中进行汽车剪刀式举升机的强度、刚度、稳定性及动态特性等方面的计算机有限元分析与研究，找出结构强度的不合理处，进行结构优化设计和改进。将改进和优化后的结构反应到Pro/E三维建模中，完成整机装配。通过有限元软件ANSYS对剪刀式举升机进行分析，可以代替剪刀式举升机物理样机的前期试验，提供更多的理论参考，进一步提高汽车剪刀式举升机的稳定性和可靠性。关键词：剪刀式举升机；力学模型；Pro/E三维建模；有限元分析；结构设计ABSTRACTAt home and abroad with the rapid development of automobile industry, car repairindustry have also been vigorously the development of Hyundai Motor vehicle lift is essential for maintenance of equipment operations, which lift the security and reliability, ease of use is that we have been Since the focus of the study. The main focus of this design is shear lift design study. Scissors-type lift mainly because of ease of use, occupying less space, subject to a number of powerful special welcome service station, which is the future direction of development of lift. In this paper, scissors-type lift to the overall structure,thecomponents of size, to determine the form of movement, the establishment of the mechanical model, and stress analysis of each lifting arm to determine the structure and material selection reasonable. After the establishment of Pro / E integrated with the ANSYS interface, will use the Pro / E after the three-dimensional modeling of the main components into finite element software ANSYS in scissors-type vehicle lift of strength, stiffness, stability and dynamic characteristics, etc. finite element analysis and computer studies to find out the structural strength of the unreasonable, the structural optimization of the design and improvement. Will be improved and optimized the structure of the response to the Pro / E three-dimensional modeling, the complete machine assembly. Through the finite element software ANSYS to analyze the scissors-type lift, can replace the scissors-type lift the pre-physical prototype testing, to provide more theoretical reference, scissors-style cfurther enhance the stability and reliability of lift.Key words: Scissors
