Dynamic performance improvement of a carpet scrapping machine

Abstract

Dynamic performance improvement like less vibration, smooth motor torque requirement, etc. of a carpet scrapping machine to enhance productivity and quality of Indian hand knotted carpets is presented. A complete dynamic analysis is carried out, along with optimum balancing of shaking force and shaking moment of machine. Inertia properties of machine are represented by dynamically equivalent systems, equimomental systems, of point-masses to identify design variables, and formulate associated constraints. Mass redistribution and counterweights are suggested methods to improve dynamic performances of existing carpet scrapping machine.
