Non-linear rail type particle damper
The invention relates to a non-linear rail type particle damper, which comprises an outer rail, a rolling wheel, buffer elements, damping cavity units and particle groups, wherein the outer rail is connected with a main body system through fixing devices; a buffer material is laid on the rail; the buffer elements are arranged at the end parts of the rail and are used for limiting the position of the rolling wheel; each damping cavity unit is a single cuboid or sphere structure; the total number of the damping cavity units is eight; a layer of particle groups is arranged inside each damping cavity unit; and each particle group consists of metallic or nonmetallic particles in round or irregular shapes. The energy consumption is realized in modes of using the self vibration of a damper mass body, the friction and collision of particles in the cavities and the like; the damping cavity units are arranged externally, so that the system movement enhancement is facilitated; the energy consumption is increased; the energy consumption efficiency of the system is high; and by using the nonlinear curve surface rail design, the system has a good reset function and automatic position limiting capability.
