摘要:磁流变液减震平台是集机械技术、控制技术和传感器测试技术、计算机信息技术于一体的综合性测试设备。磁流变液减震平台被广泛用来仿照在山地中行进的车辆、在海浪中颠簸的船舶、在恶劣气象条件下震动的飞机等的运动姿态，给予被测试件一个非常切近现实环境情状下的簸动环境，在簸动的条件下对被测试品进行实验性质的研究和相关性能的考察，在国防和民用中都有很高的价值。

磁流变液减震平台是自新世纪以来才新兴起来的新型减震平台，与它相关的一系列控制系统的设计及其可控性的研究还需要不断地完善。由于磁流变液减震平台具备能耗低、较宽的工作范围、响应时间短等一系列优点，导致其经常被运用到各种需要减震的行业领域中。

本次毕业论文对以下几点内容作出研究：（1）首先综述了磁流变液减震体验平台选题的背景和意义以及在世界范围里的研究现状。（2）然后依据磁流变液减震平台总体的性能要求和功能指标，对磁流变液减震平台的总体方案进行了规划，包括平台的总体构成、机械本体方案的确立、驱动方案的选择等。最后利用solidworks创建减震平台的三维实体模型以及相关零件的三维模型。

Abstract:Magnetorheological fluid shock absorber platform is a comprehensive testing equipment which integrates mechanical technology, control technology, sensor testing technology and computer information technology. Magnetorheological fluid damper platform is widely used to follow the road in the mountains of the vehicle, ship motion in waves, turbulence vibration in bad weather conditions such as aircraft, giving the test piece is a very close to the realistic situation of the environment vibration environment, study the experimental nature of the study and related performance of the test in a shaker under, has very high value in military and civil.

Magnetorheological fluid shock absorber is a new type of damping platform which has been emerging since the beginning of the new century, and a series of related control system design and controllability research needs to be constantly improved. Magnetorheological fluid damping platform has many advantages, such as low energy consumption, wide working range and short response time, which makes it often used in various fields requiring shock absorption.

This thesis makes research on the following contents: (1) first of all, it summarizes the background and significance of choosing the experience platform of MRF damping and the research status in the world. (2) and then based on the performance requirements of magnetorheological fluid damper and the platform overall function, general scheme of magnetorheological fluid damping platform was planned, including platform overall structure, mechanical scheme establishment, drive scheme selection. Finally, the 3D solid model of the damping platform and the 3D model of the relevant parts are created by using solidworks.

Keywords: Magnetorheological fluid shock absorbing platform, structural design, electric cylinder, 3D solid model
