振动在自然界中广泛存在,在生产技术中有着极为广泛的应用。简谐振动是最简单的周期性振动,是研究复杂振动的基础。所以本文主要就简谐振动中合成需考虑的问题、不同情况的两种简谐振动的合成进行了分析讨论,并通过计算模拟振动合成旨在加深大家对简谐振动合成的认识了解。 Vibration is widespread in nature and has a very wide range of applications in production technology. Simple harmonic vibration is the simplest periodic vibration, which is the basis for the study of complex vibration. Therefore, this paper focuses on the synthesis of simple harmonic vibration to be considered, the synthesis of two simple harmonic vibration in different situations were analyzed and discussed, and through the simulation of vibration synthesis is intended to deepen everyone’s understanding of harmonic vibration synthesis understanding.
