A crank-connecting rod electromechanical inerter device

Abstract

The invention discloses a crank-link type electromechanical inerter device, which is formed by coupling a crank-link type inerter with a cylindrical linear motor. Among them, the crank-link type inerter uses the crank-link mechanism to convert the reciprocating linear motion of the driving straight rod into the reciprocating rotational motion of the flywheel, thereby generating an inertial effect and forming an inerter, which enriches the structural types of the inerter. In addition, due to the structural characteristics of the crank-link mechanism, the crank-link type inerter can operate stably under the impact of a large load, which broadens the application range of the inerter. The material selection of the main components of the crank-link type inerter ensures the stability of the crank-link type inerter's working performance. At the same time, through the connection between the cylindrical linear motor and the external circuit, three working modes of crank-link electromechanical inerter energy feeding, passive control and active control are realized.

Description

technical field [0001] The invention relates to the technical field of engineering vibration isolation, in particular to a novel crank-link type electromechanical inerter device. Background technique [0002] In 2002, Professor Smith of the University of Cambridge proposed the concept of an inerter, which broke through the limitation of a single-end "grounding" of a mass element and demonstrated superior vibration isolation performance. Since then, the inerter has received extensive attention in the field of engineering vibration isolation. In the past ten years, the inerter has been greatly developed, and a number of effective inerter models have emerged. [0003] Although the inerter has experienced more than ten years of development, its realization is still limited to several existing structures, and there are few types of structures. Some of the existing structures are only at the theoretical stage, and only a few mature structures are easy to manufacture in practice, ...

AI Technical Summary

Problems solved by technology

Some of the existing structures are only at the theoretical stage, and only a few mature structures are easy to manufacture, which verifies the effectiveness of the structure. However, in the relevant patents, there is very little determination of the physical material of the inerter, and the actual inerter performance cannot be guaranteed

[0004] In addition, the existing inerters cannot guarantee stable operation under the impact of large loads. Like mechanical inerters, such as rack and pinion inerters and ball screw inerters, once a large load is impacted, the gear teeth or screw It is easy to break or increase the influence of nonlinear factors, thus affecting the vibration isolation performance of the inerter; while the hydraulic inerter, such as the hydraulic piston inerter and the fluid inerter, is faced with the problem of sealing sexual issues
