汽水分离再热器支座应力分析OA

At present,the calculation of the supports for horizontal pressure vessels usually adopts the empirical formula method.However,for multi-load conditions,the empirical formula method is difficult to accurately calculate the force conditions.Therefore,in this paper,the finite element model of the support of a Moisture Separator Reheater(MSR)was established by using ABAQUS software,and the stress distribution of the support under design,hydrostatic test and transportation conditions was analyzed in detail.The elastic analysis method was used to check the strength of the support and the surrounding cylinder area.The results show that the total stress is the largest under the hydrostatic test condition,and the maximum stress position is in the cylinder area in contact with the support.The strength of the support under the three conditions meets the design standard requirements.This verifies the rationality of the support scheme design,provides a theoretical basis for the strength check and structural optimization of the support,and ensures the safe and reliable operation of the equipment.
