摘要: 针对核级球阀性能评估技术应用较为困难的问题,基于Femap & NX Nastran有限元仿真及其二次开发技术进行核级球阀性能评估仿真研究,并定制仿真流程以提高其产品性能评估效率。首先,研究了阀门连接方式对结构自振频率的影响规律、轴对称球阀密封比压计算模型,以分析仿真技术有效性并提高仿真计算精度。然后,结合二次开发技术,基于设计工程师对产品性能评估的需求,定制了核级球阀性能评估仿真流程,开发了核级球阀性能辅助评估软件。最后,结合核级球阀性能辅助评估软件,对DN100核级球阀进行应用研究,以验证提出的核级球阀性能快速评估技术的有效性。结果表明该方法可以显著提高核级球阀性能评估效率,能有效实现评估过程快速化、智能化,可为其余产品的性能评估仿真流程的定制提供借鉴。
Abstract: In view of the application of performance evaluation technologies of nuclear grade ball valves is rather difficult, the performance evaluation simulation of nuclear ball valve is studied and the simulation process is customized by using Femap & NX Nastran finite element simulation and the secondary development technology in order to improve the efficiency of product performance evaluation. Firstly, the influence of the connection mode of valve components on the natural vibration frequency of the structure and the calculation model of the axisymmetric sealing specific pressure of ball valves were studied to analyse the validity of evaluation technologies and improve the accuracy of simulation calculation. Then, combined with the secondary development technology, a performance evaluation simulation procedure of nuclear grade ball valves was proposed and the corresponding performance evaluation-aided software for nuclear grade ball valves was developed on the basis of the requirements of the design engineer to evaluate the product performance. Finally, the effectiveness of the performance evaluation technology was verified by using the evaluation-aided software applied to DN100 nuclear ball valve. The results showed that the method could significantly improve the performance evaluation efficiency of nuclear grade ball valve. It also can effectively achieve the rapid and intelligent evaluation process, and provide a reference for the customization of the performance evaluation simulation process of other products.
