玻璃钢层合板等强度设计在叶片上的应用

The Iso--strength Theory of GRP Laminate in the Design of Fan Blade

本文根据文献[1]所提出的优化理论,对玻璃钢产品设计中最常用的三种层合板[无纺布0°/1:1布90°/1:1布45°]、[7:1布0°/1:1布90°/1:1布45°]、[4:1布0°/1:1布90°/1:1布45°]作了较详细的分析,提出了一个直观简便的设计方法,它对文献[2]所述的方法是一个改进,在500型冷却塔玻璃钢风机叶片设计中采用了此方法,对类似的薄壁结构也可用该法进行。为了便于工程设计使用,用FORTRAN语言编写了二个计算机程序,并均在IBM-PC机进行了验证。

This paper analysed in more.detail for laminates[7:1 woven 0°/ 1:1 woven 90°/1:1 woven 45°]、[4:1 woven 0°/1:1 woven90°/1: 1 woven 45°]、[non woven fiber 0°/1:1 woven 90°/1:1 woven 45°] which are used in design of GRP products frequently,based on the theory of optimization that is given in reference 1.It gives direct- vewing and simple design method,that has modified the procedures given in reference 2.The method is used in design of GRP fan blades of the 500 mod.Cooling tower and applies similar thin-walled structures as well.Two progroms have been compiled in terms of FURTRAN for the method that can be easily used in design.
