Abstract
Disclosed is a design method for resisting a dynamic load in a high temperature pipeline. The method includes the following steps: a first calculation step, calculating to obtain a temperature deformation displacement of each point of the pipeline; a second calculation step, calculating to obtain a modal result of the pipeline and a dynamic response displacement of each point of the pipeline; a comprehensive analysis step, comprehensively analyzing the temperature deformation displacement and displacements of the vibration modes of respective orders of the pipeline to find a position at which a rigid constraint is required to be added, and applying the rigid constraint along a direction in which the temperature deformation displacement is not affected substantially; and a determination step, calculating a stress of the pipeline and a reaction force of the rigid constraint to determine whether the stress and the reaction force meet design requirements.
