An Improved Rolling Mass Tuned Damper Based on Inertial Amplification Mechanism

Abstract

The invention belongs to the field of dampers, and discloses an improved rolling mass tuning damper based on an inertia amplification mechanism, including a slide rail, a supporting structure, a rolling mass block and an inertial body; the supporting structure is used for fixed connection with a main structure to be damped The slide rail is arc-shaped and fixed on the support structure; the rolling mass block is gear-shaped, and its rotating shaft is slidingly matched with the slide rail to move along the slide rail when the main structure vibrates; The degree of freedom of the rotation of its own rotating shaft is installed on the top of the rolling mass block through the support structure, and meshed with the rolling mass block; the inertia body is arranged coaxially with the slide rail, so that the rolling mass block is always in contact with the rolling mass block during the sliding process along the slide rail Keep engaging, thereby driving the inertial body to rotate. The invention can use smaller physical mass to generate larger inertial mass to produce obvious anti-vibration effect, thereby reducing the requirement on the size of the physical mass of the damper, and can also improve the compactness and reduce the volume of the damper.

Description

technical field [0001] The invention belongs to the field of dampers, and more specifically relates to an improved rolling mass tuned damper based on an inertia amplification mechanism. Background technique [0002] In the field of civil engineering, with the continuous maturity of construction technology, buildings are getting higher and higher, resulting in increasingly prominent vibration problems under the action of lateral dynamic loads such as wind or earthquake. At the same time, in the field of wind power generation, in order to pursue higher energy output of wind turbines, the size of wind turbines is getting bigger and bigger, and the towers are getting higher and higher. The vibration problem under the action of lateral dynamic loads such as wind or earthquake is also becoming more and more serious. cannot be ignored. Therefore, it is necessary to introduce special devices to control the vibration of towering structures such as tall buildings and fans under later...

Problems solved by technology

[0004] However, the current rolling mass tuned damper only relies on the movement of the rolling mass to dissipate the vibration energy of the main structure. When the required damping effect is high, a very large rolling mass is often required to meet the requirements, but in practical In the application, often due to insufficient installation space inside the main structure and insufficient support stiffness of the main structure, it is impossible to use a large rolling mass block, which further leads to poor vibration damping effect
