振动合成的动力学基础

The Dynamics for Composition of Vibration

文章从动力学基础出发分析了振动合成的过程,阐明了振动合成的实质是受迫线性振动系统中,驱动力的迭加.指出目前教科书中“简谐振动的合成”的提法没有实质性的物理意义,是一个错误概念,应当予以纠正.

There studies the dynamics for composition of vibration. It is found that composition of vibration in fact the composition of driving force in a linear vibration system. It is also pointed out that the incorrect notion ＂the composition harmonic oscillation＂ in most textbooks should he correct.
