Experimental validation of CAD model and to evaluated effect of Static Stiffness of rubber pad on vibro separator

Abstract

In this paper, dynamic motion analysis of reciprocating vibro separator has performed to optimize working parameters. In present paper, effect of stiffness of vibration isolator has analyze to identified chaotic region of vibro separator. CAD model of vibro separator has develop with parametric software and analyze with CAE tool for three different rubber stiffness for the dynamic motion analysis of vibro separator. Dynamic motion analyses have carried out with constant vibro-motor angle at 30⁰ and motor speed at 1000 RPM. TDR (Time displacement response), FFT and Poincaré maps have utilized to identify dynamic motion such as periodic motion, quasi periodic, multi periodic or chaotic motion of system. Live Experimental data were taken from an agriculture industry with uni-axial piezoelectric sensor with sensitivity of 1.02mv/(m/s2) along with 4-channel vibration analyzer. Computational analyses have validated with live industrial data, further parameter alteration have carried out on computational model. Outcome of present research has led to conclude that the most suitable rubber pad for horizontal vibro separator with stiffness of 100 N/mm at motor angle of 30⁰ and motor speed of 1000 + 20 RPM.
