摘要本课题为基于SolidWorks的可实现三向移动的试验台架设计的一项机械设计。机械设计，用一句话表示即是按照使用要求，从以下各方面：机械的工作原理、构件结构、运动方法、力的传递、能量的转化与传递以及零件的基本形状和材料等，通过构想、分析再计算，将其结果用专用的知识具描述出来，来给我们制造过程提供依据的工作过程。
在如今，当我们进行机械制造生产时，我们通常需要进行实验模态分析。模态分析是一种研究结构动力特性的方法，是一种应用于机械工程振动领域中的系统辨别模式。当进行试验模态分析时，我们通过试验，采集系统输入与输出信号，再经过参数识别，获得我们试验所需要的模态参数。46399
台架试验就是其中一种。每一件生产产品在出厂前后，往往需要进行特定的模拟台架试验，来检验特定的性能，以达到合格标准能投入使用。
本课题基本内容就是利用solidworks设计出可实现X-Y-Z轴三个方向移动的试验台架。
Solidworks软件有着强大的功能，由大量的组件构成。 Solidworks有三个显著特点，功能强大、易于上手和创新思维，这使得SolidWorks 成为最受人喜爱使用的三维CAD设计软件。

ABSTRACT
This topic is based on the SolidWorks can achieve three to move the test bench design of a mechanical design. Mechanical design is in accordance with the requirements of mechanical work principle, structure, mode of motion, force and energy transfer method the various parts of the materials and shape and size, lubrication methods conception, analysis and calculation and the transformation is described as manufacturing according to according to the work process.
In the modern mechanical manufacturing process, we often need to carry out experimental modal analysis. Modal analysis is a modern method to study the dynamic characteristics of structures, and it is the application of the system identification method in the field of engineering vibration. If the system input and output signals are obtained through the experiment, the modal parameters can be obtained through parameter identification, which is called the experimental modal analysis.
Bench test is one of the. Bench test is the product before or after the factory, the general need to carry out some simulation bench test, after passing through the use of.
The basic content of this project is to use SolidWorks to design a test bench which can move in three directions of the X-Y-Z axis.
Solidworks software has a powerful function, by a large number of components. Solidworks has three notable features, powerful, easy to use and innovative thinking, which makes SolidWorks become the use of leading, mainstream three-dimensional CAD design software.
Key words：Machine design；Experimental modal analysis；Test bench；Solidworks；
