The influence on human body of the acceleration caused by the elevator emergency stop has been studied. Experiments were performed with an automotive dummy in an elevator. The study is furthermore based on numerical simulations in MADYMO with an active human model. Kinematics and contact forces of volunteer experiments are used to determine the muscle activation levels. The human model is corrected for the difference between a jumping volunteer and an occupant in an elevator with buffer strike. Using the validated model, the parametric study has been conducted to study the influence of the acceleration peak height, steepness and duration.
