Enhancing Ergonomics in Automotive Cylinder Head Manual Lapping: Workstation Assessment and Design
Keywords:Anthropometry, CATIA –V5, Musculoskeletal disorder, Rapid upper limb assessment, Workstation improvement
Human factors play a vibrant part in advancing health and yield at factories. In the last 20 years, ergonomic practitioners have given importance to reshaping the workroom. Indian businesses have also initiated reshaping their workroom to avoid several Work-related Musculoskeletal Disorders (WMSD) and grievances. In this background, the project has been carried out in an automotive reconditioning workshop located in Nagpur and Pune. The ergonomic risk associated with WMSD was recognized by a comprehensive questionnaire, which was received from 18 experienced workers engaged in cylinder head Manual lapping activity. It was found that virtually all lapping workers were continuously suffering from some kind of WMSD. Based on the anthropometric data of 50 percentile Indian males, ergonomic evaluation, reshaping the existing workplace, and evaluation of a new workstation were carried out in CATIA-V5 software. To check the correction of the design, Rapid Upper Limb Assessment (RULA) for both existing as well as proposed lapping workstations was performed. This study shows that improving workstations with a structured improvement framework approach decreases the disparity between man and machine and makes the workplace comfortable for work.
