摘要
为了明确机械结合面实验箱的固有频率与振型,从理论上建立了振动动力学和模态模型,并基于有限元方法对结合面实验箱体进行了模态分析,获得了各阶模态下的固有频率和固有振型,为结合面实验装置设计和数据分析提供了一定的理论依据。
The vibration dynamics and modal were established in theory.The modal was analyzed for mechanical joint experiment box based on the finite element method in order to definite inherent frequencies and vibration modes of mechanical joint characteristic parameters. Finally, the inherent frequency and vibration mode of each mode were ob- tained. It provided theoretical basis for experiment device design and analysis of data.
