毕业论文（设计）汽车悬架系统的设计及仿真.docVIP

摘 要 悬架是汽车的几大系统中的一个主要组成部分，是确保汽车车轮与承载系统间弹性接触并减缓冲击载荷、调节阻尼振动和调整车身位置等装置的总称。悬架是保证汽车在行驶过程中能最大限度的去适应不同路面，确保汽车的操纵稳定和乘坐安全舒适性。因此，随着生活水平的不断提高，人们对生活的质量也提出了更高的要求，对汽车性能会有更多的期待，汽车制造商和相关技术人员也会对汽车悬架技术有更多的研究。这将会是一个永恒的课题。 本次课题首先对汽车悬架的几种主要形式做了一个比较全面的了解，然后结合自己本身所掌握的知识，选取其中一种型式进行设计分析。本次课题设计选择的是双横臂独立悬架，选取整车参数，参照前人总结出来的经验和公式等，计算出上横臂、下横臂、减振器等主要构件，利用ADAMS仿真分析软件进行建模仿真，分析其设计参数的合理性，并找出最优方案。 利用Adams/view进行建模并仿真，测量出主销后倾角、主销内倾角、车轮外倾角、前轮前束角随车轮跳动的变化曲线，分析其变化的范围，进而对上横臂长度、下横臂长度、上横臂在横向平面倾角、下横臂在横向平面倾角等参数进行优化，寻找最优方案，使得汽车在实际的行驶过程中减少对轮胎的磨损，延长轮胎寿命。 关键词：悬架系统；双横臂悬架；设计；仿真 Design and Simulation of Automotive Suspension System Student:LAN Xiu-mei Teacher:SHEN ZHong-hua Abstract: The suspension is a major system of the vehicle in a major part of the suspension is to ensure that between the wheel and the car carrying the resilient contact system and slow down the impact load, adjust the damping of vibration and adjust the body position, etc.General term for the device. The suspension is to ensure that the car is moving process can maximize to adapt to different road, make sure that the cars steering stability and ride safe and comfortable. Therefore, with the improvement of living standards, peoples quality of life has become increasingly demanding, there will be more research on the performance of the car automobile suspension technology will be more expectations, automobile manufacturers and related technical personnel . This will be an eternal topic. The first topic of several major forms of automobile suspension made a more comprehensive understanding, then combine the knowledge itself, choose one type of analysis of the design. I chose the double wishbone independent suspension, vehicle parameters selected with reference to the previous formula summed up the experience and so on, is calculated on the boom and lower the boom, shock absorbers and other major components, the use of three-dimensional modeling software Pro/e assembl
