Ergonomics Quantitative Evaluation and Improvement of Paper Cutting Work Based on NIOSH Lifting Equation, Metabolism Analysis and Jack

Abstract

To carry out ergonomics analysis and design improvement of paper cutting operations in a printing factory, thereby reducing work intensity and improving staff efficiency.With paper cutting station of a printing factory as the research object, this paper establishes paper cutting workers and corresponding working environment using Solidworks and Jack simulation software. For workers’ one-cycle dynamic process of paper cutting, NIOSH method in the Jack software is used to quantitatively evaluate and analyze lifting operation of the paper cutter, and analyze metabolism in workers’ all actions in one-cycle operation at the paper cutting station. Ergonomics design defects of the paper cutting station are analyzed, and optimization design is given. The improved paper cutting station is designed and simulated by Jack software, which shows that the energy consumption is greatly reduced, and workers’ metabolism value is within a reasonable range without affecting operation efficiency. Design of the paper cutting station is improved based on integrated application of ergonomics analysis software Jack and Soliworks, which reduces workers’ energy consumption and original high-load metabolism during the paper cutting operation, and increases paper cutting workers’ efficiency and comfort during the operation.
