Abstract:
(EN) Appropriate damping force that corresponds to a relative displacement amount is exerted by a simple structure. This damper has a wire member 32 wound around the outer peripheral surface of a piston 3 that undergoes relative motion within a cylinder 2, and a viscous fluid that adheres to the wire member 32 and exhibits viscous damping force. Tensile force is generated by the relative motion of the cylinder 2 and the piston 3. At lesser amplitudes, the wire member 32 deforms so that adjacently wound sections twist along the circumferential direction of the wire member 32, whereas at greater amplitudes, there is a greater tendency for the wire member 32 to deform so that adjacently wound sections are integrated. At low amplitudes, the motion of the piston 3 is smooth due to decreased friction resistance, and appropriate damping force is attained through the viscous damping force of the viscous fluid. At high amplitudes, there is a greater tendency for the adjacently wound sections of the wire member 32 to deform integrally, and the effect of frictional damping force becomes relatively greater.
(FR) Une force d'amortissement appropriée correspondant à une quantité de déplacement relatif est exercée par une structure simple. Cet amortisseur comporte un élément fil métallique 32 enroulé autour de la surface périphérique extérieure d'un piston 3 qui subit un mouvement relatif dans un cylindre 2, et un fluide visqueux qui adhère à l'élément fil métallique 32 et présente une force d'amortissement visqueuse. Une force de traction est produite par le mouvement relatif du cylindre 2 et du piston 3. À des amplitudes moindres, l'élément fil métallique 32 se déforme de telle sorte que des sections enroulées de manière adjacente se tordent le long de la direction circonférentielle de l'élément fil métallique 32, alors que, à des amplitudes plus grandes, il y a une plus grande tendance à la déformation de l'élément fil métallique 32 de telle sorte que les sections enroulées de manière adjacente sont intégrées. À de faibles amplitudes, le mouvement du piston 3 est régulier du fait d'une résistance au frottement réduite, et une force d'amortissement appropriée est atteinte par la force d'amortissement visqueuse du fluide visqueux. À des amplitudes élevées, il y a une plus grande tendance de déformation intégrale des sections enroulées de manière adjacente de l'élément fil métallique 32, et l'effet de la force d'amortissement par frottement devient relativement plus important.
(JA) 簡易な構造で、相対変位量に応じた適切な減衰力を機能させる。 シリンダ2内を相対運動するピストン3の外周面に巻き付けられた線状部材32と、線状部材32に付着され、粘性減衰力を発揮する粘性流体とを有している。シリンダ2及びピストン3の相対運動により張力が生じ、振幅が小さいほど、線状部材32は、隣り合って巻き付けられた部位それぞれが該線状部材32自体の円周方向に沿ってねじれるように変形しようとし、振幅が大きいほど、隣り合って巻き付けられた部位同士が一体となった状態で変形しようとする傾向が強くなる。振幅が小さい場合には、摩擦抵抗の低下によってピストン3の運動がスムーズになり、粘性流体の粘性減衰力により、適切な減衰力が得られる。振幅が大きい場合には、線状部材32の隣り合って巻き付けられた部位が一体的に変形しようとする傾向が高まり、摩擦減衰力の作用が相対的に大きくなる。
