摘　　要：根据RCC-P规范要求,必须采用有效措施防止高能流体管道的甩动造成核电厂重要系统和设备的损坏。一种有效的方法是装备防护屏蔽(如防甩支架)对主要部件进行实体隔离。为了验证防甩支架能否承受住管道破裂后的甩击,而不发生大的变形或者破坏,本文采用能量平衡方法对核辅助管道的防甩支架进行力学分析。结果表明,防甩支架能够承受住管道破裂后的甩击,其应力也满足RCC-M Vol.ZF的要求。According to RCC-P, it is obligatory to adopt effective measure to prevent important system and device of nuclear power plant from damage caused by the pipe whip which contains high energy liquid. To equip protective shield （such as whip restraint） to separate important components is a common effective measure to avoid pipe whip. In order to verify if the whip restraint can withstand the pipe whip without inducing failure or large displacement, stress analysis of whip restraint is performed based on energy equilibrium method, and the results show that the whip restraint can withstand the pipe whip and its stress can meet the requirement of RCC-M VoI.ZF.
