Experimental Analysis of Transient Response in Motorcycle-Rider Systems 881783

An experimental analysis has been made concerning rider sensation using several motorcycles. More specifically, the sensations evaluated are those which are related to the transient motions which are generated by a rider in an attempt to make two transient running patterns, one is to avoid obstacles and the other is lane change. Measurements were made of the steering torque, the accelerations of the major portions of the motorcycle, and the yaw and roll rates.
This experimental analysis has revealed an indicator in this system which may be of value in the analysis of rider's awareness and reaction to transient mechanical motions. We have been able to obtain results from the measurement of delay of the motorcycle-rider system in its response to the yaw rate as related to the steering torque, and power spectral density of roll rate, and these may be effective equivalent for the indexes of analysis.
