摘　　要：针对以往火电厂双进双出钢球磨原煤斗易堵煤的情况,对湖南某大型火电厂的原煤斗结构形式和外形进行了优化设计,并采用土木工程通用有限元软件MIDAS建立空间有限元模型进行数值模拟分析,通过模型修改和反复试算,确定了较为合理的煤斗结构设计方案,可以为类似工程提供参考.According to the clog of coal hoppers of steel ball mill with double inlet and double outlet of main power houses,the design of the form and structural shape of coal hopper is optimized for a large main power house in Hunan province;and by using MIDAS which is generally used in civil engineering to establish a spatial finite element model,and then it is applied to numerical simulation analysis.By model modification and trial calculation,the comparatively rational structural design scheme of coal hopper is determined,so as to give a reference for the similar projects.
