摘要对超声复合振动系统中的“局部共振”现象,基于熟知的棒或管中声波产生和传播的理论,提出一种机理解释。 - Based on the results of previous researchers , the following instigations have been carried out in this paper : ( 1 ) employing a reasonable local resonance model which can accurately embody the heat - generation behavior due to resonance and vibration - heat mode in delaminated region , the dynamic response and temperature distribution in the small delamination region of a laminated beam are formulated . influence of the excitation frequency on the temperature gradient formation is analyzed numerically , and several meaningful conclusions are drawn . ( 2 ) for laminated plates with delaminations , due to complexity of the analytical solution , the finite element method is employed to analyze their temperature distributions and satisfactory results are also obtained
本文在前人研究的基础上,对此方法进行了进一步的探讨,主要做了以下的工作: ( 1 )选取合理的、能够准确反映由共振而产生热量的行为的局部响应模型,以及合理的振动热模式,推导了一维层合梁小脱层区域的振动响应及梁的温度分布,并编制程序计算了该层合梁在激励一段时间后的温度分布趋势,分析了激励频率对温度梯度形成的影响,得到了一些有意义的结论; ( 2 )对于二维层合板,由于解析解的形式异常复杂,本文采用有限元计算软件对其温度分布进行了分析,也得到了较为满意的结果。
