Analysis of Noise at Work in Different Eccentricity and Times the Shear Coefficient of IHI Swing-Flying Shearing

分析了IHI摆式飞剪结构及工作原理,建立了剪切机构运动学数学模型.应用Matlab程序设计语言强大的数学计算和图形处理功能,将剪切机构运动学模型程序化、数值可视化,仿真出不同倍切系数、不同偏心距下飞剪上、下剪刃的运动轨迹曲线,从运动轨迹的急回特性,探究了摆式飞剪剪切机构偏心距及倍切系数对工作噪音的影响.

The paper analyses the structure and operating principles of IHI swing-flying shearing,then establishes the kinematics model for shearing framework,and compiles analysis program with powerful MatLab language in mathematic and graphics.Movement track curves for edge of shearing-knife are obtained in different eccentricity and different times.This paper also explores the noise influence in shearing work of different eccentricity and times from quick return characteristics of trajectory.
