摘 要
隨著國內(nèi)外汽車業(yè)的蓬勃發(fā)展,汽車維修行業(yè)也隨之得到大力發(fā)展,汽車舉升機是現(xiàn)代汽車維修作業(yè)中必不可少的設備,其中舉升機的安全可靠性,使用方便是大家一直以來研究的重點。本設計主要圍繞剪是舉升機進行設計研究的。主要因為剪刀式舉升機使用方便,占地空間較小,受到很多實力雄厚的特約維修站的歡迎,這也是未來舉升機的發(fā)展方向。本文首先對剪刀式舉升機的整體結(jié)構(gòu),各部件尺寸,運動形式進行確定,建立力學模型,并對每個舉升臂進行受力分析,確定結(jié)構(gòu)和選材的合理性。之后建立Pro/E與ANSYS的集成接口,將利用Pro/E三維建模后的主要部件導入有限元軟件ANSYS中進行汽車剪刀式舉升機的強度、剛度、穩(wěn)定性及動態(tài)特性等方面的計算機有限元分析與研究,找出結(jié)構(gòu)強度的不合理處,進行結(jié)構(gòu)優(yōu)化設計和改進。將改進和優(yōu)化后的結(jié)構(gòu)反應到Pro/E三維建模中,完成整機裝配。通過有限元軟件ANSYS對剪刀式舉升機進行分析,可以代替剪刀式舉升機物理樣機的前期試驗,提供更多的理論參考,進一步提高汽車剪刀式舉升機的穩(wěn)定性和可靠性。

ABSTRACT
At 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.
