| 摘 要： | 在槽式直接产蒸汽(directsteam generation,DSG)太阳能热发电系统中,传统接收器的密封装置存在结构复杂、造价昂贵等问题。为解决这些问题,研制了新型法兰机械密封结构,详细介绍了该密封装置的结构。为分析此密封结构的可靠性,利用有限元分析软件ABAQUS的热-力耦合功能,对工作过程中法兰盖板的温度场和应力场进行了数值模拟。分析结果表明,最大的应力变化出现在法兰盖板中心的热影响区,对盖板表面裂纹有主要的影响,最大应力小于材料的许用应力235MPa。

| Abstract: | In direct steam generation(DSG) parabolic trough solar generation plants,there used many receivers.In order to solve the complex configuration and high cost of the sealing device in the medium solar receiver,a novel configuration and an independent-design sealing device was developed.By using thermal-stress coupling function of the large finite element method software ABAQUS,a numerical simulation of temperature field and stress field of flange plate in working was made.The analysis shows that,the maximum s... |
