论我国振动利用工程的发展现状和发展前景

摘要

“振动利用工程”是研究振动与波利用的理论、技术及设备的一门新兴的学科。它是机械振动学三个主要分支（机械振动的理论基础、机械振动的控制和机械振动的利用）中与人类生活和生产联系十分密切的一个分支，“振动利用工程”是融机械学、力学、电工学与电子学、控制理论等为一体的交叉学科，是一门面向工程实际的技术科学。在人类生活与生产等各个方面均获得广泛应用，并已扩展到生物工程与社会经济等众多领域，目前它正处在迅速发展过程中，由于该学科所涉及的有关技术与工农业生产及人类生活联系十分密切，已正真成为人类生产活动与生活过程中一种不可缺少的手段与必要的机制。

振动（包括波动）按其类型可分为：线性与近似于线性的振动、非线性振动、波动以及电磁振荡等，因此，相应地可把振动的利用划分为在这些方面的应用。振动与波不仅已广泛应用工程技术部门，目前正在向信息技术、生物工程、社会经济领域以及人类日常生活的各个方面，预计它还会得到更进一步的发展。本文将对以上一些方面的发展做较系统的介绍，其中包括了我科研组在研究和发展“振动利用工程”中所做的一些贡献。

Recent Development of Vibration Utilization

Engineering Subject

Abstract

“Vibration utilization engineering” is a new subject, which mainly study on the theory, technology and equipment of vibration and wave. It is also the one of tree main branches (theoretical basis, control and utilization of mechanical vibration), which is closely related to human life and production.Vibration utilization engineering is an interdisciplinary subject and a technology science facing practical Engineering,which merges mechanics, electrotechnics, electronics and control theory. It has found wide application in human life and production and has been extended to varied fields, such as bioengineering, social economy, etc. At present, it is in the process of rapid development and becomes an indispensable means and essential mechanism as a result of the close relation of related technology of this subject and human life and production.

Vibration (including wave) can be divided into, according to its type, linear and near linear vibration, nonlinear vibration, wave, electromagnetic oscillation, etc. Accordingly, vibration utilization is also divided by this. Vibration and wave is not only applied in engineering technology departments but also in information technology, bioengineering, social economy and every aspect of the human daily life. It is expected that vibration and wave will further develop.

In this paper, the development of some aspects in vibration utilization subject will be systematically introduced, including some contributions of our team colleges in process of studying and developing vibration utilization engineering.

Keywords:Vibration utilization engineering; linear vibration; non-linear vibration; wave; electromagnetic oscillatio
