Description

Technical Field

[0001] This utility model relates to the field of building structure vibration reduction technology, specifically to a viscous damper with external circulation intelligent monitoring. Background Technology

[0002] Viscous dampers are passive control devices widely used in engineering structures such as buildings and bridges. They reduce structural vibration by dissipating energy through the flow of a viscous medium. Traditional viscous dampers have the following problems in use:

[0003] Poor heat dissipation performance: After long-term operation, the internal temperature rises, causing changes in the viscosity of the medium and affecting the damping performance;

[0004] Short fatigue life: High temperature and pressure fluctuations can easily lead to aging and leakage of seals;

[0005] Lack of real-time monitoring: It is impossible to intuitively obtain the working status of the damper (such as output, temperature, and pressure), which is not conducive to structural health monitoring and maintenance.

[0006] Although some dampers have attempted to integrate sensors, most are limited to single-parameter detection and lack effective heat dissipation structure design, making it difficult to achieve both high-performance heat dissipation and intelligent monitoring of multiple parameters at the same time. Utility Model Content

[0010] The external circulation system includes: an external circulation pipe;
