摘　　要：本文以带法兰螺柱结构的过滤器为例,介绍了过滤器有限元模型的建立,边界条件及载荷的施加方法;详细地介绍了基于ASME规范过滤器以及设备法兰、螺柱的疲劳分析具体过程,提出了螺柱疲劳分析的方法及注意事项,总结了疲劳容器的设计制造要求,提出了提高压力容器疲劳寿命的一些措施。Taking the filter with flanged bolt structure as an example,this paper introduces the establishment of the finite element model of the filter,the boundary conditions and the application method of the load.During the process,the method and precautions of bolt fatigue analysis are proposed,the design and manufacture requirements of fatigue vessels are summarized,and some measures to improve the fatigue life of pressure vessels are proposed.
