中文摘要:
      结合现有理论计算含有集中质量悬臂薄板模型的前两阶固有频率,并使用有限元软件分析和实验测量得到了相应的结果。发现三者有较好的一致性,可以验证使用有限元软件辅助计算的可靠性。借助一些较为成熟的有限元软件进行模态以及响应谱分析,辅助工程师求解固有频率、固有振型以及在外激励作用下的幅值等工程性问题,以避免在进行理论计算时,分析过程繁琐无法获得解析解。
英文摘要:
      The inherent frequencies in the first two steps of the model of cantilever plate with an attached lumped mass are calculated by the theoretical equation based on existing theory, then compared the relative results analyzed by finite element software and tested by experiment. The data of these three were found to have good consistency which verified reliability of finite element software in auxiliary calculation. Engineering problems like natural frequencies, inherent vibration modes and amplitudes vibrated by external excitation are analyzed by modal and response spectrum in mature finite element software, in order to avoid complexity of theoretical calculation and difficulty in achieving analytical solution.
