Problems solved by technology
Because the reason why the support and damper are set up in engineering is that the structure does not want to cause excessive deformation in this direction, that is to say, the current travel of the support and damper is limited by the installation space

The invention discloses a shear thickening liquid torsion damper under low-speed impact and a use method thereof. The shear thickening liquid torsion damper includes a displacement part, a transmission assembly, a flywheel and an airtight compartment, the displacement part includes a bearing plate and a connecting part, the transmission assembly is a ball screw, the ball screw includes a nut and ascrew rod, the nut is connected with the screw rod in a transmission mode, and the left and right side walls of the nut are both fixedly connected with the connecting part. According to the shear thickening liquid torsion damper under low-speed impact and the use method thereof, the vertical speed of the bearing plate is converted into the rotational speed of the flywheel, when the flywheel rotates in shear thickening fluid, resistance increasing with the rotational speed can be applied, and thus structural energy dissipation and vibration reduction are realized.
Description
technical field [0001] The invention relates to the technical field of torsional damper equipment, in particular to a shear thickening fluid torsional damper under low-speed impact and a use method thereof. Background technique [0002] With the rapid development of modern industry and the increasing scale of cities, the impact of vibration on the living environment and work has begun to attract people's attention. Shock and vibration are relatively common natural phenomena that widely exist in industrial production and earthquakes. In order to avoid interference and damage caused by vibration, the society has begun to attach great importance to the energy absorption and dissipation of shock and vibration. In practical engineering, such as mechanical equipment, civil engineering, etc., vibration isolation devices play a very important role. [0003] The traditional seismic isolation bearing system can be divided into three categories: the first category is the laminated rubb...
