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.

A design and development of powertrain module crash test using with the motorcycle crash test is aim to create a special tool for automotive assessment and safety engineering based on the realistic test. In order to main system of power module tester is consisting of powertrain system using electrical motor transferring system using chains and gears and control direction system using dual rails respectively. Based on powertrain module tester performance crashing speed relative angle between target and distance before crash are regarded. Nevertheless the result of testing performance was conducted to statistic hypothesis test by Mean Absolute Deviation: MAD Standard Deviation: SD Mean Square Error: MSE Mean Absolute Percent Error: MAPE and Root Mean Square Error: RMSE. The results of this approach discovered that the crashing speed was the highest error with 96% and the lowest was distance before crash. Furthermore it was corresponding to the statistic hypothesis test. However the result of the error was influence of the rails distance which limit by funding. In case of crash energy the mean of energy was appeared on 10.978 J. Whereas the tendency of variable was similar to polynomial equation.

Recently the Thai industry has continually grown up and also plays a role to economic growth in the country which affects the many of automotive components to be in the market. While the degeneration and waste of automotive components had increased as well. Therefore a crash box is one of the automotive parts which damage from the accident. Consequently the researchers have created a prototype material to develop into the crash box to reduce the environment problem from automotive parts. The random mixture of water hyacinth and husk was attempted to up to 5 ingredients. By forming a solid cylinder and 200 mm of long was used as prototype of the crash box in this research. Thus the energy absorption using compressing test was attempted to by the universal testing machine. The results showed that using polymers as a binder with 50% of water hyacinth and 50% of husk was the better ability of energy absorption. Regarding this ingredient 1612444 J/m3 of the energy absorption was referred to indicate that is the best ability of energy absorption. It is probably reduce the severity of the impact in the event of pedestrian collision.

Recently the consumption rate of vehicle is continuously an increase as an economic growth. This not only causes the massive traffic but also effects on the accidental capacity especially the road accident between car and pedestrian. The most of victims who dead are Vulnerable Road Users are crashed by the front-end structure. Regarding this problem; the possibility of the Pedestrian Crash Simulator has studied and established following the Euro New Car Assessment Programs in Pedestrian Protection. This simulator can be adjusted in 3 axles of tested position. Besides the body forms are used as impactors which are pushed the high speed drive unit via the iron less linear motor. In addition the simulator can be adjusted from 0 to 65 of degree comparing the horizontal line. As a result the limitation of the Pedestrian Crashed Simulator is linear speeds because of budget limitation. The highest of performance is not more than 3000 mm/s with 19.46 mm/s2 of speeds and acceleration respectively. However this simulator can be developed the ability by addition of the power unit and control equipment. The highest acceleration should be 35.06 m/s2 within 1.76 m. of magnetic track rail to equivalent the specified condition of the EURO NCAP (in Pedestrian protection).

Recently the Thai industry has continually grown up and also plays a role to economic growth in the country which affects the many of automotive components to be in the market. While the degeneration and waste of automotive components had increased as well. Therefore a car hood is one of the automotive parts which damage from the accident. Consequently the researchers have created a prototype material to develop into the car hood which made from the husk and water hyacinth. The random mixture of water hyacinth and husk was attempted to more than 3 ingredients. By forming a flat plate with thickness between 1 to 3 millimeters was used as prototype of the car hood material in this research. Thus the mechanical properties such as compressing and bending test were attempted to by the universal testing machine. The results showed that using resin as a binder material (Reinforced resin by water hyacinth and husk) will have the less ability of energy absorption. While using polymers as a binder (Polymer resin by water hyacinth and husk) will have the better ability of energy absorption. The properly mixture between water hyacinth and husk referred to the energy absorbing properties is 50:50 because the least linear stiffness is 1.087 N/mm. Besides the ability of energy absorption is 1612444 J/m3 which is property of this ingredient can reduce the severity of the impact in the event of pedestrians collision in the best.
