An overview of MADYMO uses at INRETS
Résumé
This paper describes the modelling approach using MADYMO 2D at INRETS (The French National Institute for Transport and Safety Research). A mathematical dynamic model of the pedestrian leg in lateral impact was developed (M.MATYJEWSKI) to test car fronts in order to estimate the severity of the knee joint lesions and to predict the risk of leg injuries in car/pedestrian accidents. Results of this model were compared with those obtained with an instrumented mechanical leg used in the bumper impact test. A train passenger behaviour during a crash at low speed was developed (J.BLOCH and F.MINNE) to improve the function of the fusible area at each carriage extremities. Results of this model were compared with those obtained during a real scale crash test. The kinematic of a 3 -year old child in a childseat on a passenger car seat is analysed (R.BIARD and J.L.CHANIAC) during a frontal impact. Experimental results from sled tests serve as a basis for the validation of the model.
