refers to the characteristics of any vibration system in the vibration, due to external effects or inherent reasons in the system, resulting in the gradual decline of amplitude, and the quantitative characterization of this characteristic.
The role of Bridge dampers mainly has the following five aspects:
(1) Bridge dampers
helps to reduce the resonance amplitude of the mechanical structure, so as to avoid structural damage caused by shock stress reaching the limit;
(2) Bridge dampers
helps the mechanical system to return to a stable state quickly after being subjected to an instantaneous impact;
(3) Bridge dampers
helps reduce acoustic radiation due to mechanical vibration and reduces mechanical noise. Many mechanical components, such as the case of transportation vehicle and the noise of saw blade, are mainly caused by vibration. Damping can effectively suppress resonance and reduce noise.
(4) It can improve the machining accuracy, measurement accuracy and working accuracy of various types of machine tools and instruments. Various types of machines, especially precision machine tools, require high seismic resistance and dynamic stability to work in a dynamic environment, and their dynamic performance can be greatly improved through various damping treatments.
(5) Bridge dampers
helps to reduce the ability of the structure to transmit vibration. In the vibration isolation structure design of mechanical systems, use damping technology reasonably can significantly improve the effectiveness of vibration isolation and vibration reduction.
