| 摘 要： | 光子挡光器是同步辐射光束线前端区的重要部件,其主要作用是阻挡高强度同步辐射.利用有限元分析软件ANSYS,对上海同步辐射装置(SSRF)前端光子挡光器,进行了精细的温度和热应力分析.分析结果表明,新设计的光子挡光器热应力水平有了显著的降低,提高了光子挡光器承受热负载的能力,满足SSRF前端部件的设计要求.

| Abstract: | The photo shutter is one of the critical parts on the front end of synchrotron radiation beam line and is usually used for absorbing high power density of synchrotron radiation.The temperature and thermal stress distributions in the front end photo shutter of Shanghai Synchrotron Radiation Facility(SSRF) were simulated carefully by the finite element package ANSYS.Analysis results reveal that maximum thermal stress of the new photo shutter is remarkably reduced and enhances the photo shutter's endurance for high synchrotron radiation thermal load,thus fulfilling the design requirement of the SSRF front end. |
