Electromagnetic friction damping module

Abstract

The invention discloses an electromagnetic friction damping module, which comprises a box body, an elastic component group, an electromagnet group and a friction component group. The box body has an accommodating seat and a cover covering the accommodating seat, and the elastic member group and the electromagnet group are arranged in the accommodating seat. The friction member set has a first friction member and a second friction member in contact with the first friction member, the first friction member is fixed on the accommodating seat, and the second friction member is fixed on the structural body. The cover body presses the elastic member group, so that the elastic member group correspondingly generates prestress and presses toward the second friction member. When the first friction member moves relative to the second friction member, the first friction member moves relative to the second friction member. The frictional force is correspondingly generated between the friction member and the second friction member, and the electromagnet group can selectively absorb the cover with an adjustable magnetic force to adjust the prestress.

Description

technical field [0001] The invention relates to a damping module, in particular to an electromagnetic friction damping module with an electromagnet group to generate adjustable magnetic attraction. The electromagnetic friction damping module of the present invention can be installed on the structure body, and the swing amplitude of the structure body can be reduced through the friction force generated between the electromagnetic friction damping module and the structure body during the vibration process of the structure body, and can be selectively By adjusting the magnetic attraction force of the electromagnet group, the size of the friction force can be indirectly adjusted. Background technique [0002] In recent years, earthquakes around the world often lead to the collapse and fracture of various buildings, such as houses and bridges, and damage to communication equipment, which not only caused heavy casualties, but also seriously affected the progress of post-disaster r...

[0004] However, the disadvantage of the aforementioned existing adjustable damping shock isolation system is that the friction between the multiple damping elements cannot be adjusted.

If the friction force between the multiple damping elements is too large, the multiple support rollers cannot roll between the lower support part and the upper support part, so that the vibration energy will directly pass through the lower support part, the multiple support parts in sequence The supporting rollers and the upper support part are transmitted to the load, resulting in excessive vibration of the load and the risk of damage.

Conversely, if the frictional force between the plurality of damping elements is too small, the rolling range of the support roller between the lower support part and the upper support part will be too large, so that the support roller will move from the lower support part to the upper support part.
