The characteristics of the damper, rotary damper manufacturers to explain for you


Rotary Damper The manufacturer believes that attenuates free vibration by various frictional forces and other obstacles called damping. The "special" component placed on the structural system can provide motion resistance and reduce motion energy, which we call a damper. Damper is also called damping device. A damping increasing device by which vibration generated by impact is quickly attenuated. The ideal shock absorber is an oil pressure shock absorber. Commonly used oils include silicone oil, castor oil, engine oil, diesel oil, engine oil, transformer oil, etc., which can be made into plate, piston, square cone, cone, etc. There are other solid viscous dampers, air dampers and friction dampers.

Rotary Damper Manufacturer believes that For shock absorption structures with metal dampers, metal dampers should only provide stiffness without yielding energy consumption under frequent earthquakes. Under the action of rare earthquakes, the metal damper shall enter a yield state and dissipate energy. When the base shear force drops well, the large interlayer displacement angle of zui shall not be less than 10%.

Rotary Damper Manufacturer believes that For newly-built seismic structures equipped with viscous dampers, under frequent earthquakes, it is recommended that the base shear force and zui large interlayer displacement angle be reduced by 15%-20%, but not less than 15%. The additional damping ratio shall reach 2%-4% of the inherent damping ratio, not less than 2%, not more than 2 times; Under rare earthquakes, the damping effect is lower than that under frequent earthquakes, but the reduction of base shear force and zui large interlayer displacement angle shall not be less than 10%.

Rotary Damper The manufacturer believes that dampers can be designed according to the speed index selected by the user, and the speed index of dampers used in civil structures can generally be between and 0.3~1.

1) Rotary damper The manufacturer believes that the damping force of the linear damper has a linear relationship with the action speed of the damper. The nonlinear damper with improved energy dissipation effect can reduce the damping output of by more than 30% while ensuring the same damping effect, thereby also reducing the load of the damper connector under large earthquakes.

2) Rotary damper manufacturers believe that At present, some people in China often choose a small speed index (such as 0.15,0.015) that is less than the 0.3 of . Generally speaking, although more energy can be consumed when the speed index is small, Taylor dampers do not recommend a speed index lower than 0.3. For shock absorbers using silicone oil, if the value is lower than 0.3, a special valve needs to be added, which not only increases the cost of the shock absorber, but also reduces the durability of the shock absorber. If the speed index value is too low, it is similar to the friction damper, which will disturb the main structure and lose the advantage of the viscous damper. Generally speaking, we can conservatively use linear dampers to calculate, but it is required to make nonlinear dampers to increase the safety reserve of the damping structure.

The above are some knowledge points about dampers. I hope you can seriously study and understand the relevant knowledge.
