Abstract: PURPOSE: A cam-spring type quasi-zero-stiffness vibration damper in an even-order polynomial shape is provided to significantly lower the manufacturing cost of a vibration damper by easily and economically manufacturing the vibration damper with a random stiffness value. CONSTITUTION: A cam-spring type quasi-zero-stiffness vibration damper(100) in an even-order polynomial shape comprises a cam(10), a roller(20), a first spring(30), and a second spring(40). The cam is combined with an object. The cam is slidably arranged in the vibration direction of the object. The roller is slidably arranged in the perpendicular direction of the object vibration direction. One end of the first spring is supported by the roller and the other end is supported in a fixed end. The first spring elastically biases the roller towards the cam. One end of the second spring is supported by the cam and the other end is supported in the fixed end. The second spring supports the cam.
