Title Structure design of a automobile accelerator pedal
Abstract
The main role of accelerator pedal is to control the opening degree of the engine throttle ,thereby controlling the speed.For the improvement of the maneuverability and the fulfillment of the higher requirement of the emission levels,the new generation management system of the electronic controlled engine need the electrical signals provided by the electronic pedal directly.As the development of the engine technology currently, eIectronic control technique must be used to meet the European III emission standard.Improvement of accelerator pedal's structure and material are needed to the designing of the homemade pedals to break monopoly.The traditional material of accelerator pedal rod changes to PA66+GF30 (containing 30% short glass line for enhanced PA66 plastic material), its economy is improved,and with the material changes the decrease of the mechanical properties of the material directly affects the reliability of the accelerator pedal rod .Therefor,this article on a certain type of accelerator rod does a FEA in a predetermined load and working condition,and it can predict the pedal structure strength in the early product design to reduce the risk and shorten the development cycle.It has very important practical significance for the development of the accelerator pedal.

1引言
1.1课题背景
当今社会，汽车己成为日常生活中不可缺少的一种工具，在发达国家，汽车的普及已到了很高的程度。以美国为例，每个家庭平均拥有各种汽车2～3辆。我国的汽车人均拥有量远远低于发达国家水平，正是由于中国巨大的市场和汽车工业对国民经济的巨人推动作用，汽车工业已被国家确定为国民经济的支柱产业，是国家扶持和重点发展的产业之一。国内汽车工业通过合资引进国际先进技术，缩短了与国外发达国家的差距，并正从引进技术逐步向自主开发过渡。经过几十年的风雨历程，中国汽车工业已形成一个比较完整的工业体系。但是在整车开发，整车性能测试等领域，国内水平与国际汽车工业的先进水平相比，尚有很大差距。
