ABSTRACT
In this paper, the status quo of China's automotive lift investigation, research, analysis, refer to lift at home and abroad to resolve the issue of security and stability of the solutions of several lift analysis, combined with the existence of our country lift the actual situation, put forward for China's auto repair industry, two-post car lift design.
This paper described the first four-post car lift for the purpose and significance of design, development and application prospects. Analysis demonstrated that the quality of a 3.2t load lifting the four-post car lift design program, a lifting mechanism of the mechanical system, hydraulic system, electrical system and other major institutions of program analysis and selection, and mechanical parts of the motion analysis, as well as strength and stiffness of the calculation of the calibration of the hydraulic system and electrical system design and calculation. The subject of computer-based simulation platform, the application of current CAD / CAE broader field of application of two-dimensional software, AutoCAD, three-dimensional soft-Pro / E, the finite element software ANSYS, two-dimensional drawings for the design of car lift, three-dimensional Solid Modeling, lift the strength, stiffness, stability and dynamic characteristics of such areas as research and analysis of computer simulation, can replace the lift of the pre-physical prototype testing, car lift for our product design, technology development theory to provide more information to further improve China-made auto lift stability and reliability, and increase market competitiveness.
