Biomechanical Modeling

Conception pour la durabilité, Ergonomie, Facteurs humains, Génie mécanique, Gestion des risques, Simulation, Corrosion sous contrainte

Objectif :

The use of mechanical principles (physics, engineering) to analyze the forces and stresses acting on and within the human body during physical activities.

Comment il est utilisé :

Computer models or mathematical equations are used to simulate human movement and calculate internal forces (e.g., on joints, spine) during tasks like lifting, pushing, or carrying.

Avantages

Allows for quantitative estimation of internal biomechanical loads that cannot be directly measured; helps understand injury mechanisms and evaluate the effectiveness of ergonomic interventions; can analyze complex movements.

Inconvénients

Models are simplifications of the complex human body and require assumptions; accuracy depends on the quality of input data and model validity; can be complex and require specialized software and expertise.

Analyzing the mechanical forces and stresses on the human body during work tasks to assess injury risk and optimize design.

Biomechanical modeling encompasses a range of applications across various sectors, including healthcare, sports science, and industrial ergonomics, where understanding human movement and forces is paramount. In healthcare, this methodology assists in designing rehabilitation programs by simulating patient movements to tailor interventions appropriately, thereby enhancing recovery outcomes. In sports science, teams leverage biomechanical models to optimize athletic performance, allowing coaches to analyze athletes’ techniques for improved efficiency and reduced injury risk during training and competition. Industrial ergonomics employs this approach during the product design phase, particularly in the development of tools, furniture, or workflows that mitigate physical stress on workers. Participants in these projects typically include biomechanical engineers, ergonomists, health and safety professionals, and product designers, working collaboratively to ensure designs meet ergonomic standards while addressing user needs. This modeling can also be particularly beneficial during early concept evaluations, allowing for rapid iterations and refinements based on simulated feedback, and is often used alongside experimental methods to validate findings through real-world testing.
