摘要

HTR-PM中的输送转换装置是保证燃料装卸系统能正常运行的重要部件

装置内管道热胀位移明显

需要支撑架具备一定的柔性;而装置中设备的质量及偏心距大

又要求支撑架有足够的刚度。采用数值模拟方法对正常及地震工况下的输送转换装置进行抗震分析

基于分析结果优化了装置的支撑方案

并根据理想支撑方案设计出压板约束形式的支撑架。该支撑架在防止设备倾覆的同时释放了热胀位移

解决了装置支撑存在的柔性和刚度的矛盾

保证输送转换装置及其支撑在极限地震工况下的安全性。

Abstract

Background: The transport & conversion devices are important guarantees for normal operation of HTR-PM fuel handling system in normal and fault conditions.Purpose: A conflict of devices’ support design needs to be solved.The flexibility of supports is required because of pipe thermal expansion displacement

while the stiffness is also required because of large devices quality and eccentric distance.Methods: In this paper

the numerical simulation was employed to analyze the seismic characteristics and optimize the support program.Under the chosen support program

the stress calculation of platen support bracket was designed by solidworks software.Results: The supports solved the conflict between the flexibility and stiffness requirements.Conclusions: Therefore

it can ensure the safety of transport & conversion devices and the supports in seismic conditions.
