转动惯量及其求法
摘要随着科学与技术的飞速发展,刚体的转动惯量作为一个十分重要的参数,使他在很多领域里受到了重视,尤其是工业领域。近几年来,伴随着高科技的飞速发展,关于刚体转动惯量的研讨,尤其是对于那些质地不均匀和形状不规则刚体的转动惯量的深入探究,已经全然对将来的军事、航空、以及精密仪器的制作等行业产生了极为深远的影响。本篇文章将在这些知识基础上,遵循着循序渐进的原则,对常见刚体的转动惯量以及不同常见规则的刚体的转动惯量的计算进行深入的研究。
本文主要分为四个部分。首先本文系统介绍了刚体以及刚体的动量矩,转动动能和转动惯量的基础知识。其次介绍了刚体的平行轴定理和垂直轴
定理,并且给出了转动惯量常见的的计算方法。接着,本文介绍了几类常见的刚体的转动惯量,其中包括圆环、圆柱体、圆盘、杆、空心圆柱体以及六面体的转动惯量。最后,通过具体实例给出了不规则刚体的转动惯量的测量方法。

pute of moment of inertia
Abstract
Delve into the irregular inhomogeneous along with the science and technology rapid development, the rigid body rotational inertia is a very important parameter, make him in many fields by the attention, especially industrial fields. In recent years, along with the high-tech rapid development of rigid body rotation inertia of research, especially for those texture and shape of rigid body inertia has pletely to the future military, aviation, and precision instrument manufacturing industry produced extremely far-reaching impact. This article will be in the knowledge base, follow the gradual principle mon rigid body inertia mon rules of rigid body rotation The calculation of inertia is deeply studied.
This paper is divided into four parts. First of all, this paper systematically introduced the rigid body and the angular momentum of a rigid body, rotational ic energy and rotational inertia based knowledge. Followed by
the introduction of the parallel axis theorem of rigid body and vertical axis theorem, and gives the rotation mon calculation method. Then, this paper introduces the mon types of rigid body's moment of inertia, which include ring, cylinder, disc, rod, hollow cylinder and hexahedron of the moment of inertia. Finally, through specific examples are given irregular rigid body rotational inertia measurem
