Active Biomechanical Rider Model for Motorcycle Simulation

This chapter describes some basic principles of biomechanical full-body models and human motor control principles. It explains how they can be applied in multibody models to simulate moving virtual humans. The chapter focuses on the biomechanical active rider model which has been developed by Biomotion Solutions. It discusses some basic aspects of how the human body processes sensory input in order to find a suitable muscle activation pattern to perform desired motions. SIMPACK is often used in automotive or wheel-rail simulation. The simulation is based on three models: the human body, the motorcycle and the motion control model. The chapter presents some simulation results to demonstrate how the biomechanical rider model is used to identify parameters of rider vibration characteristics, to investigate the influence of the rider's biomechanical parameters on the dynamic ride stability and to perform some ride simulations with road excitations to calculate the ride comfort.
