Biomechanical Model of Arms in Left-Handed Operators Using a Pedestal Drill with Fuzzy Analysis, to Improve Process Ergonomic Performance

This project addresses the need to adapt industrial tools, such as the pedestal drill, to the biomechanical characteristics of left-handed operators, as most controls are designed for right-handed individuals, increasing the risk of fatigue and musculoskeletal disorders (MSDs). The central objective is to develop a predictive model that analyzes and quantifies trunk and arm movements during operation. The methodology is experimental, exploratory, explanatory, and descriptive. Initially, a test group of left-handed operators will be selected, and anthropometric measurements will be taken. Subsequently, movements will be documented using visual techniques (video) to create an experimental database of positions and timings. This information will be used to mathematically model the movement employing second-order differential equations, referenced to a mass-spring-damper system. Furthermore, laboratory experiments will be conducted to obtain physiological data such as exerted force and muscle fatigue limits. Finally, this data will be integrated into the mathematical model to obtain the final biomechanical-ergonomic model, allowing for the prediction of musculoskeletal system fatigue time and the proposal of effective preventive measures.<br/><br/><b>Goal</b>: <br/>To design a biomechanical and ergonomic model of the trunk and arm movements of left-handed operators using a pedestal drill, with the primary goal of preventing musculoskeletal injuries associated with this work activity.<br/><br/><b>Research lines</b>: <br/>Modeling and simulation applied to industry
