Title Pneumatic test frame structure design and analysis
Abstract
In this paper, we study the structure of automobile chassis and the workings of a pneumatic components，with the two organically combined，we complete the work of pneumatic test frame body structure design.Combining with basic knowledge of mechanical of what I have learned and the existing outstanding design,we use 3D design software Solidworks completing the design of frame structure,the overall layout should be compact and reasonable as far as possible.After completion of the preliminary design,we carried out the modeling and structure strength analysis on the frame body. We use ANSYS to establish the finite element to the frame body,in order to test strength and stress to make sure those goals are met.What’s more,we simulate the axial bending and torsion by Solidworks Simulation in order to find if there is a deformation problem detection.For what is not reasonable in the design,I look for ways to improve it actively.Finally,we complete the design work of aerodynamic frame body.

1.1 课题研究背景
当今汽车数量增多，废气排放加剧，导致了许多能源与环境问题。严重的汽车尾气排放使人类生存环境受到很大污染，治理污染、节能减排的工作已经刻不容缓。同时，全球油价的不断上涨增加了汽油车的使用成本，从而推动了各种清洁能源车辆的发展。“绿色设计”已经成为新型汽车的主流设计趋势。气动汽车就是这种背景下的产物，气动汽车不同于汽油车，它是以液态氮气、空气或者压缩空气作为储能介质，依靠气动发动机或者气缸为驱动力的汽车。
