HYDRAULIC DEVICE, HYDRAULIC DAMPER, SEISMIC CONTROL STRUCTURE AND SEISMIC ISOLATION STRUCTURE
PROBLEM TO BE SOLVED: To improve non-linearity of a vibrator at its low speed range and realize a sufficient attenuation of the vibrator at its high speed range by its simple configuration.SOLUTION: A hardening hydraulic device 20 applied to a hydraulic damper 4 of a vibration control structure 1 comprises a main body part 21 and a spool valve 22. The spool valve 22 comprises a first valve part 27 for controlling an area of a first opening 23a where hydraulic oil can flow, a second valve part 28 for controlling an area of a second opening 24a where hydraulic oil can flow, and a shaft part 29 for connecting the first valve part 27 with the second valve part 28. The first valve part 27 controls an area of the first opening in such a way that an area of the first opening may become low as a first pressure is increased due to motion of the spool valve 22. The second valve part 28 controls an area of the second opening in such a way that an area of the second opening may become large as the first pressure is increased due to motion of the spool valve 22.SELECTED DRAWING: Figure 3
【課題】振動体の低速度域における非線形性を改善し且つ振動体の高速度域において十分な減衰性能を簡易な構成によって発揮する。【解決手段】制震構造１の油圧ダンパ４に適用されるハードニング油圧装置２０は、本体部２１と、スプール弁２２とを備える。スプール弁２２は、圧油が流動可能な第１の開口２３ａの面積を制御する第１の弁部２７と、圧油が流動可能な第２の開口２４ａの面積を制御する第２の弁部２８と、第１の弁部２７を第２の弁部２８に連結する軸部２９と、を有する。第１の弁部２７は、スプール弁２２の移動に起因して、第１の圧力が大きくなるに従って第１の開口の面積が小さくなるように第１の開口の面積を制御する。第２の弁部２８は、スプール弁２２の移動に起因して、第１の圧力が大きくなるに従って第２の開口の面積が大きくなるように第２の開口の面積を制御する。【選択図】図３
