The system enable the amplitude distribution of variable quantities to be obtained even for long distances or time intervals.
Main parts are: input transducers (of acceleration, forces, etc.), trigger connected with wheel revolution, amplitude analyzer, memory and printing unit. The memorized data can be elaborated in various ways, in order to facilitate any further data reduction.
An onboard prototype, directly supplied by the vehicle battery, has two channels divided into ± 32 level bands.
Typical field of application is the evaluation of the “degree of driving severity” of vehicles on various roads and circuits. This offers a basic knowledge for fatigue evaluations and road test duplications, to reproduce actual road conditions.
