摘要
目前工科类高等院校的振动教学实验中仅安排了单自由度系统的振动实验，对于物理空间的多自由度系统振动实验实现起来较为困难。文章从振动理论分析出发，以一个三自由度系统为例，介绍了多自由度系统主振型实验的设计与实现。通过理论分析与实验结果的对比，表明了实验方案的合理性与可行性。该实验已被列入我校创新型工程力学课程的教学实验，在教学实践中收到了良好的效果。
At present, the experiment of vibration in many engineering colleges and universities is carried out only based on the single freedom degree. The realization of DOF system mode shape is really difficult. Based on vibration theory, this paper introduces the design and realization by a three- degree- system experimentat. The consistency of the theory and experimental results suggests that this experinentat is reasonable and feasibility. The fact indicates that the innovative experiment has received favorable effect in our teaching process.
