Abstract:
A method for displacing a moving body (4) on a base (2) mounted elastically with respect to the ground (S), said moving body (4) being displaced linearly with a predetermined displacement under the action of a controllable force (F), wherein:a) a mathematical relationship illustrating the movements of the entity formed by the base (2) and the moving body (4) and dependent on parameters related to the base (2) and to the moving body (4) wherein said parameters vary during a displacement of the moving body, is defined; (b) using said mathematical relationship, mathematical processing is used to determine a force (F) which, applied to said moving body (4), produces a combined effect: on the one hand, on the moving body (4) so that it performs said predetermined displacement; and on the other hand, on the base (2) at least so that it is immobile at the end of the displacement of the moving body (4); and (c) the force (F) thus determined is applied to said moving body (4).
