本文研究悬臂系统,包拓悬臂弹性梁及其附带的质块的振动特性.本文首先导出了该系统频率和振型的分析表达式,并利用计算机辅助设计软件,分别讨论了质块质量及弹簧常数对系统频率的影响.上述系统的不同参数,对系统的固有频率的影响是不同的,为此我们研究了在若干特定参数下,系统固有频率对质块位置的敏感度,并得到相应的结论.
In this paper, the vibration characteristics of cantilever system, cantilever elastic beam and its attached mass are studied.In this paper, the expression of frequency and mode shape of the system is derived first, and the quality of the mass and spring are discussed respectively by using computer aided design software The influence of the constant on the system frequency.The different parameters of the above system have different effects on the natural frequency of the system, so we study the sensitivity of the system natural frequency to the position of the mass under a certain number of parameters, and get the corresponding conclusion .
