Device used for testing static and dynamic performance of damper

Abstract

The invention discloses a device used for testing the static and dynamic performance of a damper. The device comprises a main machine part, a measurement and control part and a hydraulic part, wherein the main machine part is used for executing and achieving the test on the static and dynamic performance of the damper, the measurement and control part is used for controlling the main machine part to test the static and dynamic performance of the damper, and the hydraulic part is used for providing a hydraulic energy source for the main machine part to carry out the test on the static and dynamic performance of the damper. The device can effectively improve natural vibration frequency of a mechanical part, reduce the influence on the test accuracy from the vibration of the testing device, meet the requirement for the high-frequency power test, and achieve high-accuracy test on the static and dynamic performance of the damper under actual environmental conditions.

Description

technical field [0001] The invention relates to the technical field of testing the static and dynamic performance of a damper, in particular to a device for testing the static and dynamic performance of a damper. Background technique [0002] In the past two decades, structural protection systems for bridge shock absorption have developed greatly, and the structural protection systems that have developed rapidly internationally and are widely accepted include liquid viscous dampers, metal friction pendulums, and lead rubber bearings. Wait. Installing liquid viscous dampers on the bridge to attenuate the vertical and horizontal movement of the bridge has become an important choice for design workers. Large-scale bridges that have been built or are being built in my country have also adopted liquid viscous dampers in order to reduce the impact of various vibrations on the bridge. For example, the Sutong Yangtze River Bridge, the world's first kilometer-class cable-stayed bri...

Problems solved by technology

[0004] In the norms and guidelines of European and American countries, in addition to the routine appearance inspection, withstand voltage and maximum speed tests, dynamic performance tests at different temperatures are still required when testing dampers. However, the damper test equipment in my country has not yet set up environmental control function, it is impossible to truly simulate the performance of the damper under the environmental conditions of the actual project, and it is difficult to guarantee the working performance, durability and safety of the damper
