Rotary Damper is a passive, speed-related damper. It is designed and manufactured based on the principle of damping force generated by the interaction of viscous medium and the structural components of damper . Relative movement occurs between the piston and cylinder of the rotary damper in the structure. Due to the pressure difference between the front and back of the piston, the rotating fluid passes through the damping hole, thereby generating a damping force, dissipating the vibration energy of the external input structure, and reducing the vibration response of the structure. The damping medium is silicone oil, which has the advantages of low viscosity -temperature coefficient, stable performance at extremely low and extremely high temperatures, and good radiation resistance. At the same time, it has excellent electrical insulation properties, and has excellent resistance to ozone, corona, water and moisture. The development of
rotary damper has experienced three generations of development: the first generation uses high-viscosity damping medium, which is affected by temperature, and the damping characteristics and fatigue are unstable, so the product performance is not good; The second generation uses low-viscosity damping medium and relief valve is relatively stable compared with the first generation, but the relief valve is easily damaged. This generation of products is basically not developed and applied in China. The third-generation product uses a low-viscosity damping medium, does not have an overflow valve, and adopts small-hole injection technology, which overcomes the shortcomings of the previous two-generation products. The product has stable performance and good damping characteristics. The performance of
rotary damper mainly has the following points: 1. It has a long history of development, good availability and feasibility, and high energy consumption; 2. It has a wide range of applications and can be used for earthquakes, Earthquake-resistant wind military, mechanical and building structures; 3. Easy to maintain , replacement. 4. It is a speed-related energy dissipator that does not add additional rigidity. The original structure has little effect on the dynamic characteristics. 5. The structure and connection are simple, reliable and beautiful; 6. Reduce the response of the upper structure, not only reduce the displacement, but also reduce the acceleration; 7. It can effectively play a role in all stages from small displacement to large displacement. 8. There is a phase difference between the output of the damper and the displacement response of the structure. When the displacement is minimum, the force is maximum, and when the displacement is maximum, the force is minimum.
