Embodiment Construction
[0018] The present invention will be further elaborated below by means of the accompanying drawings and examples.
[0019] Such as figure 1 Shown: a self-resetting viscous damper, including a main cylinder 1 and an auxiliary cylinder 2, the main cylinder 1 and the auxiliary cylinder 2 are connected to each other through a connecting piece 3, but not communicated. The main cylinder 1 is filled with a viscous damping fluid 4, and the viscous damping fluid 4 adopts dimethyl silicone oil. The master cylinder 1 is provided with a master cylinder head 5, and the auxiliary cylinder 2 is provided with an auxiliary cylinder head 6. The main cylinder 1 and the auxiliary cylinder 2 are provided with a guide rod 8, one end of the guide rod 8 passes through the master cylinder head 5 and is located outside the master cylinder 1, and the other end of the guide rod 8 passes through the master cylinder 1 and extends into the auxiliary cylinder 2 , The guide rod 8 is provided with a piston 7...

The invention discloses a self-resetting viscous damper. The self-resetting viscous damper comprises a master cylinder and a slave cylinder, wherein the master cylinder and the slave cylinder are connected through a connector. The master cylinder is filled with viscous damping fluid. A master cylinder cover is arranged on the master cylinder, and a slave cylinder cover is arranged on the slave cylinder. A guide rod is arranged in the master cylinder and the slave cylinder, one end of the guide rod penetrates through the master cylinder cover to be located outside the master cylinder, and the other end of the guide rod penetrates out of the master cylinder to stretch into the slave cylinder. A piston is arranged on the guide rod. A plurality of spring rods are arranged at the portion, between the connector and the slave cylinder cover, in the slave cylinder and arranged around the guide rod. A balance plate is movably arranged on the spring rods and fixedly connected with the tail end of the guide rod. Each spring rod is sleeved with a pair of resetting springs, wherein one resetting springs are arranged between the balance plate and the connector, and the other resetting springs are arranged between the balance plate and the slave cylinder cover. According to the self-resetting viscous damper, self-resetting of the piston can be achieved, and the residual displacement of a structure can be effectively eliminated. In addition, the self-resetting viscous damper is simple in structure and stable in performance.
Description
technical field [0001] The invention belongs to the technical field of vibration reduction, in particular to a viscous damper with self-resetting function. Background technique [0002] The viscous damper has the characteristics of small stiffness and high energy consumption. Its vibration reduction mechanism is to dissipate the energy input into the structure through the viscous characteristics of the damping fluid and the porosity effect, thereby reducing structural vibration (earthquake or wind vibration) ) to reflect and protect the safety of the main structure. [0003] The components of the viscous damper in the prior art include a main cylinder and an auxiliary cylinder connected to each other through connecting pieces, the main cylinder is filled with viscous damping fluid, the main cylinder is provided with a main cylinder cover, and the auxiliary cylinder is provided with an auxiliary cylinder cover, The piston slides inside the master cylinder. But this viscous ...
