Crank connecting rod type electromechanical inerter device

Abstract

The invention discloses a crank connecting rod type electromechanical inerter device which is formed by coupling a crank connecting rod type inerter and a cylindrical linear motor. The crank connecting rod type inerter utilizes a crank connecting rod mechanism to convert the reciprocating linear motion of a driving straight rod into the reciprocating rotary motion of a flywheel, so that an inertiaeffect is generated, the inerter is formed, and the structure variety of the inerter is enriched. Besides, due to the structural characteristics of the crank connecting rod mechanism, the crank connecting rod type inerter can stably operate under large-load impact, and the application range of the inerter is widened. Materials of main components of the crank connecting rod type inerter are selected, and the stability of the working performance of the crank connecting rod type inerter is guaranteed. Meanwhile, the cylindrical linear motor is connected with an outer-end circuit, so that three working modes of energy feedback, passive control and active control of the crank connecting rod type electromechanical inerter 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
