Abstract
The paper describes a three-dimensional computer simulation of the impact of motorcycles and dummy riders with flat, vertical, rigid barriers inclined at various angles to the initial direction of travel. The computer model has two main features for both the motorcycle and the dummy. They both consist of articulated rigid bodies with non-linear compliant joints and with contact models superimposed. Velocity-related non-linear algorithms are used to describe contacts between the dummy rider, the motorcycle and the barrier. The simulation has been applied to a series of full-scale crash tests. The model is currently being extended to incorporate safety features such as leg-protectors and air-bags into the motorcycle and also to replace the rigid barrier by a moving car.
