Throughout the history of the automobile, safety, both inside and outside the vehicle, has been a crucial issue. Active safety focuses on preventing accidents from occurring, while passive safety is concerned with protecting passengers or pedestrians in the event of an accident. The objective of this research is to design an impact platform where an anthropomorphic mannequin of a three-year-old child simulating Osteogenesis Imperfecta in the long limbs will be placed, performing frontal impact tests. The methodology was carried out with the help of a flowchart consisting of six stages, ranging from studying different commercial impact platforms to speed and acceleration calculations, design, manufacture, instrumentation of the impact platform, and analysis of the results obtained. The result of this research was the design of an impact platform for low-speed testing, where exciting data was obtained through the instrumentation of the dummy. This allowed us to determine some of the injuries that a child with osteogenesis imperfecta might suffer in frontal impact, whether or not they were wearing a seatbelt.
