3、mm,工作压力0.6MPa,介质温度3009，环境最低温度-109，补偿器安装温度209,根据管道布局（如图），需安装一内 压式波纹补偿器，用以补偿轴向位移X=32mm，横向位移Y=2.8mm，角向位移0=1.8 度, 已知L=4m，补偿器疲劳破坏次数按15000次考虑，试计算支座A的受力。解：（1）根据管道轴向位移X=32mm。Y=2.8mm。0=1.8 度。由样本查得0.6TNY500x6F的轴向位移量X0=84mm，横向位移量：Y0=14.4mm。角位移量：00=8度。轴向刚度：Kx=282N/mm。横向刚度：Ky=1528N/mm。角向刚度：K0=197Nm/度。用下面关系式来判断此补
