| 摘 要： | 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.

| Abstract: | The vibration of cantilever system including elastic cantilever beam at-tached to mass is researched in this paper. Expression of analyses for system natural fre-quencies is derived. By using CAD software, the influence of mass and spring constant on system natural frequencies and mode shapes is discussed respectively. The influence on systme natural frequencies is different from the above different parameters. To some spe-cial parameters, the susceptibility for system natural frequencies to the place of mass is researched and the corresponding conclusions are derived. |
