板弹簧角度对振动料斗振幅的影响

针对目前振动料斗板弹簧在安装角度设计时缺乏理论依据的缺陷，通过对振动料斗工作时板弹簧的弹性变形进 行分析，实现了一种基于拉格朗日方程法振动料斗数学模型的建立。利用MATLAB仿真模块分析了不同板弹簧安装角 度对振动料斗振幅的影响。仿真结果表明，在保证零件能够输送的前提下，板弹簧安装角度大的振动料斗其振幅小，输 送零件时冲击和噪音小，适合输送精密零件；安装角度小的振动料斗其振幅大，适合在工作环境要求不高的场合输送零 件。文章的研究为设计输送不同物料的振动料斗提供了理论依据。

Influence on Vibratory Bowl Feeder with Different Leaf Spring Angle

As lacking the theory in the design of leaf spring installing angle of vibration bowl feeder, through the analysis of elasticity deformation of leaf spring on the vibratory bowl feeder. a mathematical model of vibratory bowl feeder system was established by using Lagrange equation. By using MATLAB software. the simulation of vibratory bowl feeder on different degrees of leaf spring installing angle was carried out. The simulation result reveals that under the premise to ensure parts can be transported, the vibratory bowl feeder has a smaller amplitude with a larger leaf spring installing angle, the shock and noise is small when conveying parts which is suitable for conveying precision parts; and a larger amplitude with a smaller leaf spring mounting angle which is suitable for low requirements for conveying parts. The research provides theoretical basis for vibratory bowl feeder design transporting different material.
