Biomechanical Analysis of Workstation Improvement in Actuator Arm Damper Assembly of Hard Disk Drive Industry

Abstract

The objective of this research is to apply Biomechanical Analysis to find forces and moments thateffect to parts of body from outside forces, loading and working postures by gathering knowledge ofMechanics, Anthropometry, Anatomy and Physiology to be Mathematical Model. Results in this research wereforces and moments at hand, lower arm, upper arm and back joints and especially emphasized on findingcompressive force at L5/S1 lumbar discs . About Ergonomics problems, tables in above mentioned processwere low. Researchers tried out to improve table to be 10 centimeters higher, then we assessed operatorsxpostures by using Biomechanical Model in both before and after adjustment period. Results showed thatcompressive force at L5/S1 lumbar discs were 24.83% reduced in new adaptive workstation.
