Design and Research of Carbon Fiber Composite Lightweight Pump Truck Hydraulic Cylinder

针对泵车变幅液压缸轻量化需求,设计了一种碳纤维复合材料液压缸。主要针对液压缸的缸筒和活塞杆进行了轻量化结构设计,并利用ABAQUS有限元软件对其进行了仿真分析。研究结果表明:对于缸筒,0°铺层可以有效降低缸筒的应力和位移;对于活塞杆,增加90°铺层能够有效提高活塞杆的刚度。同时,相较于金属液压缸,碳纤维复合材料缸筒减重26%,碳纤维活塞杆减重约57%,减重效果明显。

To meet the lightweight requirements of luffing hydraulic cylinder of pump truck,a carbon fiber composite hydraulic cylinder with a lightweight design was proposed.In this paper,the lightweight structure of the cylinder barrel and piston rod of the hydraulic cylinder was designed,and simulated and analyzed using ABAQUS finite element software.The results show that for the cylinder barrel,a 0°ply can effectively reduce the stress and displacement,while for the piston rod,adding a 90°ply can effectively improve stiffness.Additionally,compared to a metal hydraulic cylinder,the weight of the carbon fiber composite cylinder barrel is reduced by 26%,and the weight of the carbon fiber piston rod is reduced by about 58%,demonstrating a significant weight reduction effect.
