Advanced musculoskeletal simulation as an ergonomic design method

Discrete event simulation as an ergonomic tool to predict workload exposures during systems design

This methodological paper presents a novel approach to predict operator’s mechanical exposure and fatigue accumulation in discrete event simulations. A biomechanical model of work-cycle loading is combined with a discrete event simulation model which provides work cycle patterns over the shift resulting in a load-time trace for the entire shift. This trace was tested with four different muscle ...

Colossal Tooling Design: 3D Simulation for Ergonomic Analysis

In manufacturing, ergonomics and human factors issues must be considered during the design and utilization phases. These applied human factors concerns include but are not limited to, reach ability, visibility, lift factors, kilocalorie usage, repetitive motion, ventilation, lighting, and many more. When the tool size becomes colossal, say 35 feet or more in diameter and 90 feet or more in leng...

Ergonomic Assessment of Musculoskeletal Disorders' Risk Factors in Construction Workers Using Cornell Questionnaire and WERA Method

Introduction: With regard to high prevalence of musculoskeletal disorders in the construction industry workers, the aim of this study was to investigate the prevalence of musculoskeletal disorders and their relevant risk factors in workers of a construction factory. Methods: This descriptive-analytical cross-sectional study was conducted in 2019. In this regard, 150 workers were selected from ...

Relationship between Job Stress and Ergonomic Behavior with Musculoskeletal Disorders in an Auto-part Production Company

Background & Aims of the Study: Worker’s behaviors, uncontrolled job stress, psycho- social factors and non-ergonomic principles, lead to risk of musculoskeletal disorders. This rsearch was done conducted to analyze relationship these factors in an auto-parts production company in Qom province, Iran in 2015. Materials and Methods: This study was a cross-sectional one condu...
