Booster Seat Dynamic Parameter and Damage Analysis

Abstract:

In order to reduce the rate that child passengers injury their chest and head in a collision, parameter analysis of child restraint system is performed. Based on multi-body dynamics software MADYMO, child occupant crash simulation model is built. In accordance with the laws and regulations, the validity of the model is verified. Damage criterions, such as head the centroid synthesis of acceleration, HIC36 and resultant chest acceleration, are used to analyze the influence of different coefficients on childs injury, including friction between booster seat and vehicle seat, safety belt stiffness and friction between the dummy and safety belt. Results show that increasing the coefficient of friction of boost seat bottom and seat belt by coating them with friction material can reduce childs head and chest injuries significantly during the collision.
