Design of bionic compression curved hammer head based on clustering algorithm
针对人工踩曲劳动强度高、效率低,传统的机械制曲技术无法达到人工踩曲效果等实际问题,开展基于聚类算法的仿生压曲锤头设计.通过对人工踩曲足底生物力学数据采集和足底各区域受力分析,深入研究足底在踩曲运动中的受力特性,基于K-means聚类算法,结合MATLAB软件和拉格朗日插值法对异常值的修正,对采集的足底生物力学数据进行分析.将足底区域划分为4类,仿真结果显示,SSE为15189.35,CH分数为1343.6,轮廓系数为0.8279,划分后的同一类别压力特性相近.以划分后同一类别的足底区域为压力单元模块,组合设计仿生压曲锤头.相比于平板锤头及曲面锤头,仿生锤头的提浆效果面积比分别提高5.94%,3.19%,内部均匀因子分别提高3.9%,1.07%.研究为压曲锤头的研制提供参考.
For the practical problems such as high labor intensity and low efficiency of manual treading,and the inability of traditional mechanical quilling technology to achieve the effect of manual treading,a bionic quilling hammer head was designed based on the clustering algorithm.Through the collection of plantar biomechanical data and analysis of plantar force in each region of the artificial treading,the force characteristics of the plantar in the treading movement were studied in depth.Based on the K-means clustering algorithm,combined with MATLAB software and Lagrange interpolation method for correction of outliers,the collected plantar biomechanical data were analyzed by clustering.The plantar region was divided into 4 categories,and the simulation results show that the SSE is 15189.35,the CH score is 1343.6,and the contour coefficient is 0.8279,and the pressure characteristics of the same category after division are similar.The same category of plantar region after division was used as the pressure unit module to design the bionic koji press hammerhead in combination with the design.The bionic hammerhead design improved the area ratio of pulping effect by 5.94% and 3.19%,the internal uniformity factor by 3.9% and 1.07% compared to the flat and curved hammerheads.The study provides a reference for the development of pressing hammer heads.
