摘要：【中文】本发明公开了一种装配式的压力自平衡磁流变阻尼器，活塞杆采用两段分体式结构，主活塞设置于第一活塞杆和第二活塞杆的连接处，主活塞将主缸筒分为左右两个密封腔室，磁流变阻尼液填充于两个密封空腔内，第二活塞杆的内部设有空腔，空腔内部的副活塞将第二活塞杆的内部空腔分隔为两个密封空腔，副活塞在两侧压力作用下可以沿活塞杆的内壁自由移动，本发明一方面在实现阻尼力可调节的同时可以避免阻尼器在极限工况下的出力过大，又可以避免阻尼器本身的损坏；另一方面，能够通过拆卸更换活塞、活塞杆与线圈的方式调整阻尼器的耗能性能，有效减低生产成本，利于产品零部件的工业化生产与储存。 【EN】The invention discloses an assembled pressure self-balancing magnetorheological damper, wherein a piston rod adopts a two-section split structure, a main piston is arranged at the joint of a first piston rod and a second piston rod, the main piston divides a main cylinder into a left sealing cavity and a right sealing cavity, magnetorheological damping liquid is filled in the two sealing cavities, a cavity is arranged inside the second piston rod, an auxiliary piston inside the cavity divides the inner cavity of the second piston rod into the two sealing cavities, and the auxiliary piston can freely move along the inner wall of the piston rod under the action of pressure on two sides; on the other hand, the energy consumption performance of the damper can be adjusted by disassembling and replacing the piston, the piston rod and the coil, so that the production cost is effectively reduced, and the industrial production and storage of product parts are facilitated.
