以速度变换和负载自适应的双活塞组合液压缸为研究对象,根据液压缸的结构特点和工作原理进行了相关方程的推导并建立了数学模型。利用AMESim软件搭建了液压缸系统模型,由仿真得到双活塞组合液压缸运动过程中参数变化的动态曲线并分析得出相关结论。同时,研究了切断阀阀口直径、切断阀阀芯形状和三角槽对液压缸动态性能的影响,为双活塞组合液压缸系统的节能研究及设计应用提供了重要的理论支撑。
Abstract
Taking speed-transformation and load-adaptation double piston combination hydraulic cylinder as the research object, according to the structural characteristics and working principles of the hydraulic cylinder, we derive out the related equation and establish the mathematical model. We use AMESim to build the hydraulic cylinder system model, and by simulating, the change curves of parameters of the cylinder’s dynamic performance obtained. The effects of the port diameter, the shape of the shut-off valve and the triangular groove on the dynamic performance have also been studied, which provide the important theoretical support for double piston combination hydraulic cylinder system energy saving research and design.
