【摘要】 恒力弹簧吊架是核电站管道支撑及悬吊主要设备。由于核电站项目的特殊性,恒力弹簧吊架零部件的应力分析与强度计算是设计过程中必不可少的环节,是恒力弹簧吊架正常稳定工作的保证。这里对三连杆恒力弹簧吊架进行力学分析,得到弹簧力与回转臂转角的关系曲线。应用三维造型软件建立了回转臂的实体几何模型,给出了回转臂模型简化方法。利用有限元方法对回转臂进行应力分析,得到回转臂不同转角下应力分布规律。分析结果表明本设计满足核级电站产品的设计要求。更多还原

【Abstract】 Constant hangers are main pipe supporting devices in nuclear power stations.Because of being used in nuclear power stations,the stress analysis is strictly requested in the phase of parts design to ensure safty and reliability with the given normal load.Based on mechanical analysis of one type of three links constant hanger,the spring force-arm angle curves are obtained.Solid geometrical model of the arm is bulit by using the 3-D software.The stress of the arm in different angles is obtained by way of finite element analysis.The analysis result shows the design can meet the specification level used in nuclear power station.更多还原
