    r        支吊架弹簧的选择和安装整定计算方法 r

    r

    r        计算需要的原始数据是:支吊架的工作荷重、热位移大小和方向。计算的内容包括:弹簧类别和弹簧号选择、串联或并联数量、弹簧的安装压缩值、工作过程的转移荷重和荷重变化率。 r

    rr        下面介绍的方法,是以第二节所述理信纸为基础的计算方法。rrr        先按给定的工作荷重,确定弹簧的Pmax值以确定弹簧号。为了选择方便,将弹簧系列的工作荷重和允许热位移范围表格化,列于表2—4中。表2—5则是弹簧系列的工作荷重和允许热位移范围。rrr                                            支吊架弹簧(83年版)工作荷重和允许热位移范围rrr        表2—4rr
