Abstract
A dynamic lifting model was developed which provided a lifting profile with the associated biomechanical loads at each joint within the dynamic strength limits. A mathematical programming approach was used to simulate and evaluate lifting tasks to avoid the need for human motion tracking experiments, data collection, and data analysis procedures. The hypothesis on which the model was based was that human lifting patterns follow the principle of minimizing mechanical work, while maximizing the utilization of the musculoskeletal system. Two lifting tasks were simulated using the model. The first example was lifting from floor to knuckle height and the second dealt with lifting from floor to shoulder height. The simulation study paid particular attention to the mechanical behavior of the link system and demonstrated that the associated differences between the predicted motion and the measured motion was biomechanically feasible and the accuracy was considered adequate with an average U statistics ranging from 0.012 to 0.209.
