The thermowells of different shapes have their own characteristics, including their natural vibration frequencies and the stress distributions. The selection of the thermowells shape should be based on the vibration characteristics and the stress distributions. In the past, the designer are eager to learn about the characteristics of different shapes thermowell, but due to lack of analysis of vibration frequency for different shapes thermowell, therefore, in the engineering design, selection of thermowells shape seemed more random. In recent years, with increased discussion and further research on the issue of themowell vibration and stress makes possible to study shapes impact on vibration and stress of thermowell. Based on the ASME PTC19.3 TW-2010, this paper makes analysis and comparison of the natural vibration frequencies and the stress distributions of thermowells of three shapes and provides some guidelines for the selection in engineering applications., authors=SUN Jiren, authorsList=SUN Jiren, authorCompany=SINOPEC Engineering Incorporation, Beijing 100101, China, correspAuthors=null,

articleAbstract=温度计套管有多种形式,在工程应用中,比较常见的是锥形、直形和阶梯形。不同形状温度计套管的振动频率和受力情况各不相同,有各自的适用特点。以往,尽管设计人员渴望了解不同形状温度计套管在振动和受力方面的特性,但由于缺少不同形状温度计套管振动频率和受力情况的分析对比,因此,在工程应用设计中,对温度计套管形状的选择比较随意。近年来,随着对温度计套管振动问题讨论的增多和研究的深入,使得研究形状对振动和受力的影响成为可能。本文根据ASME PTC19.3 TW-2010提供的准则,通过对上述3种形状的温度计套管振动频率和受力强度的分析对比,提出不同形状温度计套管的适用特点,为工程应用中的选型设计提供参考依据。, authors=孙吉人, authorsList=孙吉人, authorCompany=中国石化工程建设有限公司,北京 100101, correspAuthors=null, authorNote=null,
