Inertial mass vibration reduction system with adjustable inertial mass coefficient

Abstract

The invention belongs to the field of variable inertia mass control, and particularly discloses an inertia mass vibration reduction system with an adjustable inertia mass coefficient. The inertia massvibration reduction system involves a flywheel main body, mass blocks, actuators, guide rails, a control unit and a base, wherein the flywheel main body is arranged on the base; the plurality of guide rails extending towards the radial direction of the flywheel main body are uniformly distributed and connected to the peripheral edge of the flywheel main body, and one mass block is arranged on each guide rail; and the actuators are arranged on the flywheel main body and used for independently pushing the mass blocks to slide on the guide rails where the mass blocks are located under the control of the control unit, so that the inertia mass vibration reduction system has the actually-needed inertia mass coefficient, and stepless adjustment of the inertia mass coefficient is achieved. According to the inertia mass vibration reduction system, the mass blocks can be controlled to be close to or away from the center of a flywheel according to a control instruction in the control unit, so that the inertia mass coefficient of inertia mass can still be adjusted at will after installation, that is, the inertia mass coefficient of the inertia mass can be adjusted and controlled in a steplessmode; and redisassembly and reassembly are not needed in engineering application, so that the inertia mass vibration reduction system is very convenient.

Description

technical field [0001] The invention belongs to the field of variable inertial mass control, and more specifically relates to an inertial mass damping system with adjustable inertial mass coefficient. Background technique [0002] Inertia is a structure in which the reaction force generated is related to the relative acceleration at both ends. Specifically, the force generated is equal to the product of the inertia coefficient and the relative acceleration. The inertia coefficient is an attribute of the inertia itself, such as the flywheel type Inertia, whose inertia coefficient is related to the moment of inertia of the flywheel. Inertia mass itself is very small, but it can produce a large mass effect. Since the inertial mass was invented, its application range has been expanding, such as TID system, TVMD system, etc. The biggest advantage of the inertial mass system is that it can simulate a large mass effect, and it is mostly used for vibration reduction of cables such ...
