Performance Test Research of New Viscous Damper. Issue 1 (January 2021) - Luo, Ye
Abstract: With the progress of engineering, technology viscous damper are widely used in the field of engineering structures. Its principle is that when the external normal disturbance on the structure, the viscous damper will not generate damping force on the structure; when there is a strong external disturbance (strong earthquake, strong wind), The dampers can produce a reaction force, which can reduce the damage of the structure and improve its seismic capability. In this paper, the new viscous damper has been experimentally tested, including: 1. Test for maximum damping force; 2. Test for damping coefficient, damping exponent; 3. hysteresis curve. By analyzing the experimental data, the actual performance parameters of the new viscous damper are obtained, which provides certain support for future mass production and use of the product.
