摘　　要：一种燃油锅炉的回燃室围板采用了非椭圆异型结构,强度校核难以套用常规的计算模式。本文运用有限元ANSYS软件进行计算,采用逐步释放围板边界约束的方法,得到不同联接方式下异型回燃室围板的最大应力值和应力分布图,并采用第三强度理论对围板结构进行评定和强度校核。分析结果表明,异型回燃室围板满足强度要求。与常规计算结果相比,当施加边界约束条件接近围板实际工作状况时,提高了计算精度。A fuel boiler combustion chamber back coaming is a non elliptical irregular structure,Finite element Intensity checking is difficult to apply to conventional computing models. The ANSYS software is used to calculate, get the stress distribution pattern and the maximum stress value of the hatch plate of the special-shaped reversal chamber coaming plate under different connection modes by using the method of gradually releasing the coaming plate boundary constraint. Besides, using the third strength theory to check and evaluate the structural strength. The results show that the special-shaped reversal chamber coaming plate satisfing the strength requirements.
