Description

Technical Field

[0001] The utility model belongs to the field of environmental vibration and noise control, and in particular relates to an adaptive electronic damping vibration reduction and isolation device. Background Art

[0002] Vibration refers to the reciprocating motion of an object at its equilibrium position, or the back-and-forth change of a system's physical quantity near its equilibrium value. Object vibration is one of the common phenomena in nature. In many cases, vibration is considered a negative factor. For example, vibration can affect the function of precision instruments and equipment and reduce processing accuracy; vibration can aggravate structural fatigue and wear, shorten the service life of machines and structures; vibration can cause the collapse of bridges, flutter of aircraft wings, and vibration of wheels. Vibration control not only affects the performance of instruments and the service life of machinery and equipment, but also affects the normal work of operators and the vitality of ships and spacecraft. Therefore, vibration control has become a hot topic in the field of vibration engineering research.

[0003] Adaptive vibration dampers / isolators can actively adjust the vibration according to the vibration conditions of the equipment during operation, thereby effectively reducing the vibration generated by the equipment and improving the performance and stability of the equipment. This is very important for equipment that requires high precision and high stability, such as precision instruments, experimental equipment, etc. At the same time, it also reduces the wear of equipment parts caused by vibration and can extend the service life of the equipment. For some production processes and experimental research, vibration may have a negative impact on product quality. By using active vibration dampers / isolators, it can be ensured that the equipment does not generate excessive vibration during operation, thereby improving the quality of the product. In addition, vibration is often accompanied by noise. Active vibration damping / isolating the equipment can effectively reduce the generation of noise and help maintain a relatively quiet working environment.
