提升机卷筒法兰结构优化

针对钢丝绳的缠绕方式,测量了6.5 mm钢丝绳在受拉压力作用下的弹性模量。正确地分析了法兰的受力情况,建立了法兰受力分析的三维有限元模型,并得到了实验验证。采用该模型对4.0 mm厚法兰的3种不同加强肋结构进行了计算,在考虑了零件的强度和成形的难易程度后,选取了24根直肋的结构。从而,达到了将法兰厚度从5.0 mm减薄到4.0 mm的目的。正确设计法兰结构,对减轻法兰重量、节省材料和提高提升机的承载能力有着重要的意义。

Structure Optimization of Lifter Reel Flange

According to the winded way of steel wire rope,the elastic modulus of 6.5mm steel wire rope under tension and pressure measured.After correctly analyzing the force conditions of the flange,a 3D finite element model about the force analysis was built,and it was verified by experiments.The model was used to calculate three different rib stiffener structure of 4.0 mm thickness flange.The structure of 24 straight rib stiffeners was selected by carefully comparing the parts strength and forming difficult degree.Then,the thickness of the flange was decreased from 5.0 mm to 4.0 mm.It is significant that correct design of flange is help for reducing flange weight,saving raw material and improving lifter's carrying capacity.
