惯容器模型结构探索

Researh on the Inerter Structure

针对惯容器模型的实现装置种类少及实现方法单一的问题,从设计理论角度出发,探讨惯容器模型结构及其实现方法。基于惯容器是一种被动式两端点机械网络元件,可以利用不同的机械零件加以实现的特点,通过研究齿轮齿条式、滚珠丝杠式这一类封装飞轮惯性为特征的惯容器,提出了以封装质量惯性为特征的一类惯容器;针对这两类惯容器均为平动元件,无法进行转动机械网络综合这一问题,进一步提出了扭转惯容器的概念,并找到了实现装置;阐明了装置的基本设计原理。研究发现,惯容器以多种形式存在于平动机械系统中,扭转惯容器客观存在于转动机械系统中。

The realization devices for the models of inerter elements are rare, and their realization ways are single. In view of such facts, inerter devices and their realization ways were discussed from the point of view of design theory. Inerter is a passive mechanical element and its concept can be realized by different mechanical structures. Based on the research of the devices such as ＂rack-and-pinion inerter＂, ＂ball screw inerter＂ characterized by packaging inertia of a flywheel, a realization way of inerter devices characterized by packaging inertia of a mass was presented. The two types of devices are both translatory elements, therefore rotatory mechanical networks can not be synthesized with them. In terms of this issue, the concept of the rotatory inerter is proposed, furthermore, two devices satisfying the concept are found. Besides, fundamental design principle ＂of the devices was demonstrated. The research indicates that the inerter exits in translatory mechanical networks in various forms and the rotatory inerter objectively exits in rotatory mechanical networks.
