Dynamic aalysis of a small weaving loom

Abstract

The project deals with an investigation to determine experimentally the axial and bending strains (normal to the plane of the mechanism) in the two connecting rods of the weaving mechanism of a small textile loom. A complete theoretical, kinematic, force and stress analysis has been made on the six-bar chain constituting the mechanism. The peak to peak strain values have been measured at various different crank speeds. The nature of the bending strains in a direction normal to the plane of the mechanism have been further examined by static tests which have been performed on the mechanism. Measured dynamic strain data for the connecting rods is presented and comparison is made between calculated and measured values. Experimental results for axial peak to peak and cyclic strain variation showed good agreement with the calculated values
