摘 要

汽车已成为人们日常生活必备的交通工具，汽车减震器在汽车零部件中占有极其重要地位。减震器是汽车悬架系统中的关键部件，减震器的性能就决定了悬挂系统的许多性能参数。而且减震器的好坏直接决定了汽车的乘坐舒适性和行驶的平顺性。

随着计算机在软、硬件上的快速发展，虚拟设计无论是在理论，还是在计算技术方面都已取得巨大的进步。虚拟设计是较先进的现代设计方法。虚拟设计不仅可以大大降低开发成本，还缩短了开发周期，提高了企业的竞争力。所以，虚拟化设计越来越受到企业的欢迎。

本文主要讲述了利用CAD软件UG对减震器各个零部件进行实体建模，然后着重分析了减震器的制造生产工艺，最后在UG软件的制图模块获得了完整的工程图纸。根据实践情况，利用通用有限元软件ANSYS对减震器的阀片进行有限元建模、计算、应力分析、应变分析，根据分析结果对减震器的阀片受力变形情况进行了解。

Abstract

Automobile has become an indispensable transportation means of our daily life , and the shock absorber is an important part of the car. Shock absorber is play as an important role in the automobile suspension system, because it decide automobile suspension system performance. And it also decide the Vehicle Ride Comfort and Vehicle Ride Comfort.

With the computer in software and hardware on the rapid development of

virtual design, whether in theory or in the calculation of the virtual design have made tremendous progress. Virtual design is a modern design method. Virtual design can help us to reduce development costs and shorten the development

cycle,so it is more and more popular by the enterprise.

This article introduces the modeling of the shock absorber by CAD software, study on the production of the shock absorber and get the engineering drawing in UG software. At last, according to practice, use the general-purpose finite element software ANSYS to finite element modeling, calculation, stress analysis, strain analysis, based on an analysis of the results of the valves of the shock absorber deformation understanding of the situation.

Keywords：shock absorber three-dimensional modeling product design
