Analysis of frontal protection system on a car

摘要

Pedestrian accidents caused by car in Indonesia is quite high. Pedestrian injuries during a collision between a car and a pedestrian can be fatal. In Indonesia, the old cars is still used because there are no regulations which restrict the using of a car based on the production year of vehicles. The old cars do not have some features to protect the pedestrians in the condition of a collision between a car and the pedestrian. The objectives of this study is to determine the effect which occur in the conditions of a collision between a car and a pedestrian by creating a direct collision simulation using a dummy as a form of artificial pedestrians and MPV car as a case study. Direct collision simulation process resulted in injury points on dummy. The injury rate was obtained by the area damaged from direct collision simulation process by calculating the surface area of injury on dummy. The design of the proposed pedestrian protection was to minimize of pedestrian injury suffered by using FAST. The outlining descriptions of the functions on the front part of the car were obtained by brainstorming. The additional function for pedestrian protection that previously did not exist at the front of the car was proposed in the form of Additional Frontal Protection System, e.g. with a height below the average human knee (496 cm) and a material which could absorb the impact was recommended. By applying the Frontal Protection System, the function of the front part of the car will increase so that the value of the car itself will increase consequently.
