Large-tonnage inerter type self-resetting damper with variable apparent mass
The invention discloses an apparent mass variable large-tonnage inerter type self-resetting damper which comprises a connecting end, an apparent mass variable flywheel, a ball nut, a ball screw, a thrust bearing, a multi-layer annular spring, an inner rod, a steel base plate, a fastening nut and an outer sleeve. The variable apparent mass flywheel is composed of a chassis, buffer rubber, a movable sliding block, a guide rod and a spring, the left end of the ball screw is fixedly connected with the connecting end, the right end of the ball screw sequentially penetrates through the variable apparent mass flywheel, the ball nut and the thrust bearing and is fixedly connected with the inner rod, and the inner rod sequentially penetrates through the left side steel base plate, the multiple layers of annular springs, the right side steel base plate and the fastening nut. The variable inertia capacity coefficient is achieved through the variable apparent mass flywheel composed of the chassis, the buffer rubber, the movable sliding blocks, the guide rods and the springs, and large-tonnage damping force is provided through the multiple layers of annular springs with friction energy dissipation and self-resetting capacity. Therefore, the damper has the advantages of variable apparent mass, large tonnage and self-resetting.
本发明公开了一种表观质量可变的大吨位惯容型自复位阻尼器，包括连接端、可变表观质量飞轮、滚珠螺母、滚珠丝杠、推力轴承、多层环形弹簧、内杆、钢垫板、紧固螺母和外套筒，可变表观质量飞轮由底盘、缓冲橡胶、可移动滑块和导杆以及弹簧组成，滚珠丝杠左端与连接端固结，右端依次穿过可变表观质量飞轮、滚珠螺母和推力轴承，并与内杆固结，内杆依次穿过左侧钢垫板、多层环形弹簧、右侧钢垫板以及紧固螺母。本发明通过装有由底盘、缓冲橡胶、可移动滑块和导杆以及弹簧组成的可变表观质量飞轮来实现惯容系数可变，通过具有摩擦耗能和自复位能力的多层环形弹簧提供大吨位阻尼力，从而使得阻尼器具备表观质量可变、大吨位和自复位的优点。
