新型碗状海蜇螺旋切割系统设计及仿真研究与验证

针对碗状海蜇切丝方法中人工切丝效率低、成本高,液压驱动切丝机能耗大、易产生污染等缺点,设计了采用伺服电缸驱动的新型碗状海蜇螺旋切割系统;应用SolidWorks构建了切割系统各零部件的三维实体模型,利用HyperMesh/LS-DYNA进行动力学仿真,动态模拟螺旋切刀切割海蜇过程,以及海蜇皮失效和刀路形成过程,得到海蜇切丝过程中剪切力变化曲线与应力、应变及动态特性变化,并通过验证实验证明了仿真结果的有效性。

Design and simulation research and verification of a new bowl-shaped jellyfish spiral cutting system

In order to overcome the shortcomings of manually cutting the bowl-shaped jellyfish, with inefficient and costly, high consumption of energy and serious pollution, a new bowl-shaped jellyfish spiral cutting system driven by a servo electric cylinder was designed. The corresponding three-dimensional solid model was constructed by using SolidWorks software and the dynamics simulation of the spiral cutting system was completed by HyperMesh/LS-DYNA software. Moreover, the process of cutting jellyfish with spiral cutter, the process of jellyfish skin failure and knife path formation were dynamically simulated. The change curve of shear force, and the characteristics of stress, strain and dynamic during the cutting process of jellyfish were obtained, and the validity of the simulation results was confirmed by experiments.
