Parce que cette revue propose parmi ses thèmes privilégiés celui de la rigidité des structures, la question de la déformabilité d’une structure a été considérée en des termes statiques plutôt que cinématiques. Cet article a pour but de montrer la mobilité du chaînon mécanique,vue par le cinématicien, et de I’apparenter aux possibilités de mouvement relatif d’une structure. Nous ànalysons les sujets de structures (structures à barres et noeuds), systèmes de panneaux à charnières et polygones spatiaux, d’un point de vue cinématique de manière à ce que I’on puisse faire une simple comparación avec I’approche statique.
Because this journal has as one of its main concerns the subject of structural rigidity, the question of the instantaneous deformability of a structure has been considered in statical terms rather than kinematic ones. This article is intended to put forward the kinematician’s treatment of linkage mobility and to relate it to the internal motion cabability of a structure. We consider the topics of frames (bar-and-joint structures), hinged panel systems and spatial polygons from a kinematic standpoint in such a way that a ready comparison may be made with the statical approach.
