Harmonic Response Analyses of Three Knife-Shape-Tooth Star-Wheel Loading Mechanism

Abstract:

In order to research dynamic natures of a three knife-shape-tooth star-wheel loading mechanism, a mechanical model and a solid model of the star-wheel loading mechanism are established by means of updated-Lagrange and ANSYS software in the paper, equivalent stress clouds and displacement responding curves of the star-wheel at different excitation frequencies are obtained through harmonic response analyses. Model analysis shown that the star-wheel loading mechanism doesn’t take place resonance when the excitation frequency locates between 1.8 and 2.4 Hz, and the star-wheel works stability when the rotation speed is from 36 r/min to 48 r/min. These conclusions from study lay a theoretical foundation for improving the design of a three knife-shape-tooth star-wheel loading mechanism and make better its dynamic behavior.
