The invention discloses a rocker bearing water tank damper, and belongs to the technical field of energy dissipation and vibration attenuation of civil engineering structures. The rocker bearing water tank damper comprises a plurality of rocker sliding support saddles, a water tank, a damper support saddle, a box column, and a viscous damper; each rocker sliding support saddle comprises an upper support saddle plate, a metal ball and a lower support saddle plate; the upper support saddle plate is fixed at the lower surface of the water tank; the lower support saddle plate is fixed on an upper top plate or a spandrel girder of the structure; the upper saddle plate is opposite to the lower saddle plate; the metal ball is placed in the middle to achieve oppositely sliding between the upper support saddle plate and the lower support saddle plate; the box column is arranged at the bottom part of the water tank; the damper support saddle is arranged on the upper top plate or the spandrel girder of the structure; and the viscous damper is horizontally arranged between the box column and the damper support saddle. By adopting the rocker bearing water tank damper, on one hand, the adverse effect of a high-level water tank on the structure under the horizontal load is removed; and on the other hand, dynamic response of the structure under the horizontal load is greatly reduced by the formed water tank damping system. The rocker bearing water tank damper is stable in damping effect, simple in structure, safe and reliable, good in durability, and strong in designability.

The invention relates to a composite vibration isolation device based on particle damping and a memory alloy material. The composite vibration isolation device comprises an elastic part and also comprises a particle damping part and an auxiliary limit vibration isolation part. The particle damping part contains a particle damping chamber, particles and a soft material, and the auxiliary vibration isolation part comprises a memory alloy bar, a laminated plate, rubber and a base plate. The particle damping part can be combined with the auxiliary limit vibration isolation part by virtue of technologies such as welding and bolted connection, and the auxiliary limit vibration isolation part can be connected with the elastic part, a lower base plate and the base plate by virtue of bolts or in a welding manner. By virtue of damping energy dissipation of the particle damping part and hyper-elasticity of the memory alloy bar, the composite vibration isolation device provided by the invention integrates vibration attenuation and energy dissipation into a whole and overcomes the defect that an existing vibration isolator has a poor damping effect when the frequency is lower than 20Hz, and the vibration isolation effect is better enhanced. The composite vibration isolation device provided by the invention is applicable to vibration isolation of a track in the field of track traffic and can be also applied to vibration isolation of equipment foundation or floors of sensitive buildings.

The invention relates to a vibration-reducing and damping structural part of a portable electronic device and a notebook computer. The vibration-damping structural part of the portable electronic device includes: a damping cavity, which is opened on the casing of the portable electronic device; a cover plate, which covers the damping cavity; and a vibration-damping component, which is placed in the above-mentioned damping cavity. The above-mentioned damping cavity can be independent, or divided into several sub-damping cavities by partitions. The vibration-damping components mentioned above can be particles, thin rods, flat plates and the like. The vibration-damping structural components of the portable electronic equipment of the present invention, when periodic or non-periodic vibrations are caused by external forces such as vibration, drop, impact, etc., especially random vibrations, the vibration-damping components enclosed in the cavity move and collide with each other It consumes a lot of energy, absorbs and consumes a lot of vibration energy, and reduces the harm caused by vibration. The damping structure is compact, light and thin, and the damping does not change with temperature in the range of -40-80°C, which is its excellent characteristic.

The invention discloses a motor with anti-vibration and shock absorbing functions, which includes a base assembly, a bearing assembly, and a pressure-stabilizing shaft assembly. A pressure stabilizing shaft assembly is arranged inside the assembly. The mist in the pressure stabilizing tank of the present invention will slowly accumulate at the bottom of the pressure stabilizing tank under the action of gravity, and is atomized by the water flow atomizing component to form a cycle of water molecules, and the aerosol mixture is in the At the same time of vibration isolation, it can effectively cool down the area of ​​the motor drive shaft and improve the continuous operation performance of the device. The invention can effectively avoid the characteristics of poor vibration damping effect of pure gas, and avoid the low flow rate and easy accumulation of pure liquid vibration damping The characteristics of poor flexibility can avoid the poor stability of spring vibration reduction, and the characteristics of spring aftershocks are easy to drive the surrounding objects to swing, and the vibration reduction effect is stable.
