A vibration damping component for a vehicle includes a housing, and a mounting lug attached to the housing. The mounting lug includes an outer shell with a top, a bottom, and sides. The mounting lug also includes a bore through the outer shell from the top to the bottom. The mounting lug also includes a cavity, an interior lattice, and a damping media. The outer shell and the bore enclose the cavity. The interior lattice is within the cavity and stiffens the mounting lug. The damping media is enclosed in the cavity and between solid portions of the interior lattice.

The present disclosure relates to an energy dissipation device and system, comprising a hollow cylinder adapted to be filled with solid balls, and a longitudinal member/shaft having short rods protruding radially therefrom. The shaft having rods is movably disposed of within the hollow member and solid balls are filled and secured in the cylinder thereafter, such that two ends of the longitudinal member extend outside of the hollow member, and the rods and solid balls remain within the hollow cylinder. The ends of the device may be configured with structures or equipment. The movement of the shaft along a longitudinal axis of the cylinder, upon receiving an energy impact in an event of seismic activity, wind loads, and/or man-made vibrations, results in friction between the solid balls and the rods of the shaft, which facilitates dissipation of the received energy.

A damping shock absorber includes a pipe and a plurality of shock absorbers configured on the pipe. The shock absorber includes a main body sleeved on the outer periphery of the pipe and a damping medium filled in the main body. The main body is provided with an inner cavity, and the inner cavity is divided into a plurality of chambers for placing the damping medium separately. A method for designing the damping shock absorber, wherein the main body is filled with the damping medium, such that the shock of the pipe or a shaft body is reduced, ensuring the smooth operation of the pipe or the shaft body, and further ensuring the safety and efficiency of the pipe or the shaft body in a working process. The damage to the pipe or the shaft body and the shock interference to other linked apparatuses are greatly avoided.
