大型玻璃钢渔船帽型骨架剖面参数的力学分析

本文对大型玻璃渔船帽型架剖面参数，进行了在不受力情况下正交各向异性玻璃钢薄板稳定的力学分析，建立架受力分析－受压区的矩形薄板压缩稳定和腹板的矩形薄板剪切稳定两种力学模型，解得这两种力学模型，在两种材料（１：１玻璃钢和４：１玻璃铡）与两种边界件（四边简支和四边固支）组合的四种条件下，骨架剖面参数的ｂ／ｔ１和ｈ／ｔ的取值范围，它们依次为１０．０～２６．２和２８．７～４４．２。文中分析结果为帽型骨架剖面

Mechanics Analysis for Section Parameters of Cap- shape Frames of Large FRP Fishing Vessels

In this paper, the section parameters of the cap - shape frame of the large FRP fishing vessel is analyzed by elastic stability theory. Both two models of thin rectangle plates on compression and shear stability are established. The section parameter b/t1 and h/t are obtained in four cases that is the four combinations for two materials (1: 1FRP and 4:1 FRP) and two boundaries (all edges simply supported and all edges clamped). The ranges are from 18.0 to 26. 2 and from 28.7 to 44.2 respectively. The results provide theory basis for the optimal design of section parameters of the cap - shape frame and the revision of relevant standard.
