Rigidity-variable self-resetting damper and working method thereof
The invention relates to a rigidity-variable self-resetting damper. A cavity of an outer sealing cylinder is filled with a damping material; two limiting partition plates are arranged outside the guide rod in a penetrating mode, and the outer edge end faces of the limiting partition plates abut against and are limited by the end face of the inner limiting cylinder. The limiting partition plates sequentially divide the closed barrel into first-order springs on the two sides and a second-order spring in the middle. The end face of the inner limiting cylinder abuts against the limiting partition plate, and application and maintaining of pre-pressure on the second-order spring are achieved. A damping hole for communicating the area where the first-order spring is located with the area where the second-order spring is located is formed in the limiting partition plate; the first-order spring, the second-order spring, the partition plate and the limiting partition plate form a multi-order rigidity self-resetting core; inner cylinders are fixedly arranged on the inner sides of the left sealing end cylinder and the right sealing plate respectively, and fixed baffles are arranged on the outer sides of the inner cylinders and fixedly connected with the guide rods; the first-order spring, the second-order spring, the inner cylinder, the partition plate and the limiting partition plate are only arranged on the outer side of the guide rod in a sleeving mode and can slide relative to the guide rod.
本发明涉及一种刚度可变自复位阻尼器，外密封筒腔体内填充阻尼材料；导杆外穿设有2个限位隔板，限位隔板外缘端面受到内限位筒端面的抵压限位；限位隔板将密闭筒体依次隔开形成两侧的一阶弹簧和中间的二阶弹簧；内限位筒端面与限位隔板相抵接，实现对二阶弹簧预压力的施加与保持；限位隔板上开设将一阶弹簧所在区域和二阶弹簧所在区域连通的阻尼孔；一阶弹簧、二阶弹簧、隔板与限位隔板，构成多阶刚度自复位核心；左密封端筒、右密封板内侧各自固定设有内筒，内筒外侧设有固定挡板，固定挡板与导杆固定连接；一阶弹簧、二阶弹簧、内筒、隔板与限位隔板只套设于导杆外侧，可相对于导杆产生滑动。
