FEA技术在CT新床体开发中的应用

FEA Technology Applied in the Design of CT Table

该文主要以CT扫描床体为例,详细的介绍了在CT床体的开发过程中如何应用FEA技术进行建模、建立边界条件以及进行静态强度和刚度分析,特别是对如何将具体的、实际的工作情形简化为模型中抽象的边界载荷条件进行了详细的介绍。最后将FEA分析结果与实际实验结果进行对比,对FEA分析结果的准确性进行了确认,得出FEA技术在医疗器械产品开发中的重大应用意义。

In this paper, we develop a method to build FEA model, boundary conditions and to analyse static strength and rigidity of the object based on the CT patient table. Especially to introduce the examples of how to simplify the actual models to ideal models which can easily add some loads. In the end of the paper, we compare the results analysis of FEA with the results of experiment and we confirm the high accuracy of FEA, so we summarize that FEA technology is very important for the development of medical equipments.
