A Design and development of motorcycle anthropometric test dummy

Abstract

The purpose of this research is to design and develop dummy (anthropometric test dummy) for motorcycle frontal collision test. The conceptual design of dummy is male, aging between 25-55 years old, 6 pieces of rib and deformable 76.2 mm. In order to performance test, it was classified into 2 testing by static testing and dynamic testing. For static testing, the energy absorption behavior between force and deflection or “ static curves” is determined. While dynamic testing is considered to the energy absorption behavior between forces and several velocities or dynamic forcedeformation curves, impact acceleration, impact force on sternum and injury severity with the relationship of viscous in velocity function. The results of the energy absorption behavior on chest of dummy from static testing, the tendency of chest deflection is relatively low during the initial force and suddenly increasing when rise to the critical point. This behavior is similar to the energy absorption of the human chest. Therefore, the design features of this test dummy can reflect behavior that is close to the human anatomy. In case of dynamic testing, it is discovered the ability of the dummy testing to absorb up to 560 J, impact acceleration 3 8 . 4 3 g, impact force on sternum 5 . 0 9 4 kN. The viscous in velocity function is 0 . 8 2 5 m/ s which compared to injury severity at AIS3+ ( or higher than serious injury) . Therefore, the dummy design in this research project corresponds to the collision test of a motorcycle.
