摘要
针对细胞分离实验中同时需要摇床和离心机设备，而市场上的摇床和离心机功能单一，不能同时满足摇床和离心机的功能，浪费实验室空间和研究经费问题，提出了设计一种能实现摇床和离心机功能的多功能离心机。本文主要介绍了多功能离心机的机械部分设计过程。首先介绍了离心机和摇床的基本原理和结构组成，并确定了多功能离心机的总体方案。根据理论计算得到零部件的结构形式及尺寸。零件结构设计完成后，在UG软件中对设计的零件进行三维建模，并装配成整体，实现多功能离心机整体建模。利用UG建模可以直观地反应出零件之间的关系，可以检验出设计中存在的问题，例如零件之间相互干涉的问题。发现问题可以到零件的模型中进行修改，装配图会自动更新。检查装配图没有问题以后，导出工程图，然后生成二维图，完成了多功能离心机机械部分设计。

Abstract
Both needs in view of the cell separation experiment in shaking table and to need the centrifuge, but in the market the function of the shaking table and the centrifuge is unitary, cannot simultaneously satisfy function of shaking table and the centrifuge, wastes the laboratory space and the research funds. Proposed designs one kind multi-function centrifuge to be able to realize the shaking table and the centrifuge function. This article mainly introduced the multi-function centrifuge mechanism part design process. First introduced he basic principle and the structure composition of centrifuge and shaking table, and has determined the multi-purpose centrifuge overall plan. Obtains the structural style and the size 0f the part according to the theoretical calculation . After the components structural design completes, carries on the three dimensional model in UG software to the design components, and assembles the whole, realizes the multi-purpose centrifuge overall model. Using the UG model may direct-viewing respond the relations between the components, may examine the question which in the design exists, for example between the components mutually interferes question. Found the problem may arrive the components in the model to carry on the revision, the assembly drawing can automatically renew .The inspection assembly drawing does not have after the question ,derives the engineering plat, then the production two dimensional plot , has completed the multi-function centrifuge machine part design.
