Platform reproducing periodical movements in three axes, with a preferential direction.

摘要

Moving platform intended to reproduce periodical movements along three axes (longitudinal, transverse, vertical) with a preferential direction (XX), the said platform (2) being carried via a baseplate (1) on the one hand, at one end (termed "rear") by means of at least one leg (3) coupled to a crank (7) and, on the other hand, at the other end (termed "front") by link rods articulated to the said baseplate, characterised in that the said crank (7) is carried by a support (9) connected to the baseplate (1) by a leg (9a) which can be moved laterally such that the crank (7) finds itself either in a vertical plane comprising the preferential direction (XX), or in a plane which is oblique to one side or the other, and in that the two front legs are each articulated onto a link rod (15, 20) which is substantially vertical, each link rod (15, 20) being articulated directly or indirectly at its lower end to the baseplate (1). <IMAGE>
