Abstract
In order to minimize the error resulted from finite element analysis models of heat exchanger prevent misguidance to other cases,the relations between non-static loads and structure deformation of heat exchanger are discussed according to the engineering practice in 11 situations from three aspects.The first aspect includes a kind of follow-up load between body flange and sealing surface of flat gasket under internal pressure.The second aspect includes 4 kinds of vibration load during operation,3 kinds of cyclic load during operation.The third aspect includes 3 kinds of cyclic load during fabrication.All those dynamic loads are worthy of paying attention to in the high-grade finite element analysis model of heat exchanger.关键词
