Abstract
A method for determining the efficiency of a vehicle's shock absorbers, comprising the following operational steps: identifying, by virtue of image acquisition means, at least one point of the vehicle rigid with the shock absorber lower connection, and at least one point of the vehicle rigid with the shock absorber upper connection; associating said at least two points with a cartesian reference system; subjecting the vehicle or at least a wheel thereof to a non-horizontal forcing stress; memorizing a succession of photograms in order to acquire the equations of motion of said at least two points and calculating the equation resulting from the difference between the two equations of motion; determining from said equation the parameters necessary to evaluate the shock absorber efficiency.
