Title
(EN) REMOTE ELASTIC CENTER MACHINE
(FR) MACHINE A CENTRE D'ELASTICITE DISTANT
Abstract
(EN)
At least either of the upper and lower portions of each of a plurality of elastic bodies (30) provided between an upper structure (10) and a lower structure (20) is movable radially, simultaneously by the same distance in the longitudinal direction of the elastic bodies manually or by a driving means to change the position of an elastic center X, which exists in the axial direction of the machine body, and change the elastic force between the upper and lower structures (10, 20). Either of connections of each of the elastic bodies (30) to the upper and lower structures (10, 20) is a hinge joint or a spherical pair joint, and that of the other is a fixed joint. Alternatively, the upper and lower structures (10, 20) are joined to each other by a plurality of elastic bodies (30), and the connections between the structures and the elastic bodies are hinge joints or spherical pair joints, and at least either of the connections of each body is provided with a fixing means for restraining the degree of freedom of rotation thereof.
(FR)
La partie supérieure et/ou la partie inférieure ou ces deux parties d'une série de corps élastiques (30) comportant une structure supérieure (10) et une structure inférieure (20) se déplacent dans le sens radial, simultanément selon la même distance dans le sens longitudinal du corps élastique, par une man÷uvre manuelle ou par l'effet d'un mécanisme modifiant la position d'un centre d'élasticité X qui est placé dans l'axe du corps de la machine et modifiant la force élastique entre la structure supérieure (10) et la structure inférieure (20). L'une des connexions de chacun des corps élastiques (30) aux structures supérieure et inférieure (10, 20) est constituée par une liaison à charnières ou par une liaison articulée sphérique, l'autre étant une liaison fixe. Selon une autre possibilité, les structures supérieure et inférieure (10, 20) sont réunies l'une à l'autre par une série de corps élastiques (30), et les connexions entre les structures et les corps élastiques sont constituées par des liaisons à charnières ou par des liaisons articulées sphériques, tandis que au minimum l'une des connexions de chaque corps est munie d'un dispositif de fixation limitant le degré de liberté de sa rotation.
