Abstract
As is often the case with motorcycle-to-car accidents, the motorcycle falls over and slides before it hits a passenger car. The resulting vehicle deformation is unique. Past experimental data is unsuitable to assume the energy absorption of this unique deformation. Therefore, the motorcycle speed estimation is difficult in this type of accident and it has been long desired to acquire experimental data which would be valid for these cases. Responding to this requirement, a series of impact tests has been carried out i.e., sliding motorcycles were deliberately crashed into the side of passenger cars at various speeds. The results have shown that the deformation of the sides of the passenger cars reflect the the speed of the motorcycle. On the other hand, motorcycle deformation is less useful for the purpose of determining the speed at which impact occurred. The deformations of the test vehicles were carefully analyzed and a numerical estimation equation has also been proposed.
