使用caesar计算弹簧支吊架的有关问题？ 1.设计思路是什么，为什么选择弹簧支吊架。 mainly due to expansion/contraction, settlement, frost heave, or... a. reduce stress level or nozzle load b. control deflection c. re-distribute restraint force if required d. decrease vibration mag. (seldom used) e. special purposes, such as as-built 2.怎么选择的恒力还是可变支吊架，区别在哪。 a. normally max. variability of vsh is 25% (very often, =20%), for sensitive equipment nozzles, may use =10%. based on the vertical movement and load (c or h), select suitable vsh (type, fig, and size) to meet the req. b. if the variability is too large, or no vsh can be selected, use csh c. if the installation height of vsh is too high, also select csh d. cost estimation, e. anvil or equivalent csh may be not reliable due to lose load during transition 3.有弹簧支吊架的时候，一般都分析那几个loadcase。 all of the cases shall be evaluated, including some extreme conditions, for example, w/o content, installation, pin-out, and initial displ. 4.当有弹簧支吊架的时候，caesar的使用的注意事项都有那些。 a. caesar spring selection may not be perfect b. the cases may not be stressed c. special cases must be properly considered when a piping engineer does a cal d. height of vsh affects the software selection of spring. e. etc. ......................................................................查看更多
