Computer-aided strength prediction using the articulated total body model

The Articulated Total Body (ATB) Model, based on rigid-body dynamics with Euler equations of motion and Lagrange type constraints, has been used to predict the forces and motions experienced by air crew personnel in flight operations. But can be adapted to less abrupt stresses as experienced by typical industrial workers. To provide a more realistic representation of human dynamics, an active neuromusculature was added to the ATB Model via the newly developed advanced harness system. Furthermore, the ATB Model was used to simulate the whole body response to lateral forces utilizing trunk musculature. Although the musculature did not completely prevent the lateral deflection of the body, the response was significantly delayed compared to a control response, with the head and neck maintaining the upright posture for a longer period of time.
