ISO13232, which defines test and analysis procedures for research evaluation of rider crash protective devices fitted to motorcycles, recommends 200 configurations of simulation calculations. Considering the diversity of configurations, the multi-body dynamics based software "MADYMO" (MAthematical Dynamic MOdel) rather than FEM based software was adopted in the present study as a basic simulation tool. In this research, a prototype test vehicle was selected as the motorcycle model, and a prototype airbag system was used as an example of a protective device. To determine the impact characteristics of the motorcycle front structure and the contact characteristics between the motorcycle and the rider dummy, several component tests were performed. Prescribed motion simulations and a barrier test simulation were also carried out to validate the motorcycle model. As a result, this model was found to show good performance in simulating the motorcycle to dummy contact and the motorcycle to barrier impact. For the covering abstract see ITRD E825082.
