Samenvatting
A nonlinear, four degree of freedom digital simulation of a motorcycle has been developed. The equations of motion have freedom in the lateral, roll, way and steering modes, and the system comprises the main frame plus the rider, the steering and front wheel masses, a rotating front wheel, and a rotating rear wheel and engine. A seven degree of freedom, nonlinear model is described which has pitch, bounce, and variable forward speed added to the four degrees of freedom of the simpler model. Results obtained from the two models are compared.
