【摘要】 过滤器在使用过程中可能承受内压和外压,另外,为保持合适的过滤器壳体内介质温度,过滤器壳体外往往设置盘管。针对带盘管壳体强度与刚度设计问题,本文采用有限元法,对过滤器进行极限载荷分析和线性屈曲分析,考察外盘管对极限载荷和屈曲临界载荷的影响。结果发现盘管对极限载荷没有明显影响,但能显著提高设备的屈曲临界载荷。更多还原

【Abstract】 Filters may be subjected to internal pressure and external pressure in service.In addition,in order to maintain a proper temperature of the medium in the filter shell,coils are often set outside the filter shell.In this paper,aiming at the design problem of the strength and rigidity of the shell with coil,the limit load analysis and linear buckling analysis of a filter are conducted with finite element method to investigate the influence of the outer coil on the limit load and the critical buckling load.It is found that the coil has no obvious influence on the limit load,but it can significantly increase the critical buckling load of the equipment.更多还原
