Broadband inertia enhancement vibration isolator and novel vibration reduction track
The invention provides a broadband inerter enhanced vibration isolator and a novel vibration reduction track, the broadband inerter enhanced vibration isolator comprises an outer cylinder, a spring, a particle damping inerter and an inner cylinder, the inner cylinder is sleeved with the outer cylinder, the spring is arranged in the inner cylinder, and the particle damping inerter is sleeved with the spring; the particle damping inerter comprises a ball screw pair, a flywheel containing particles and a base. The flywheel and the ball screw pair are coaxially and fixedly connected to a nut of the ball screw pair. The first end of the ball screw pair is fixedly connected to the outer cylinder, and the second end of the ball screw pair is connected into the base and can rotate around the shaft. The broadband inertia enhancement vibration isolator is composed of the outer cylinder, the spring, the inner cylinder and other parts, the particle damping inerter is an inerter, has the characteristics of a particle damper and is applied to a track, and the full-band comprehensive vibration reduction capacity of the spring floating slab track can be effectively improved.
本申请提供一种宽频惯容增强型隔振器及新型减振轨道，其中宽频惯容增强型隔振器，包括外筒、弹簧、颗粒阻尼惯容器和内筒，内筒套设在外筒内弹簧设置在内筒中，颗粒阻尼惯容器套设在弹簧内；颗粒阻尼惯容器包括滚珠螺杆副、内含颗粒物的飞轮和基座，飞轮与滚珠螺杆副同轴固定连接于滚珠螺杆副的螺帽处；滚珠螺杆副的第一端固定连接在外筒上，第二端连接在基座内并可绕轴旋转。本发明提供的宽频惯性增强隔振器由外筒、弹簧以及内筒等零部件组成，其中的颗粒阻尼惯容器既是一种惯容器，又具备颗粒阻尼器的特点应用于轨道上，能有效提升弹簧浮置板轨道的全频段综合减振能力。
