摘要:
本文针对有限元动力模型提出了一个新的修正公式。该公式充分利用了有限元计算的结果和实测模态参数,只需少数几阶固有频率和振型,即可对初始理论模型进行动态修改。通过模拟计算了一个四阶系统和对一个实际结构的修正,结果证实了所提出的方法的有效性。
Abstract:
In this paper a new formula for dynamic modification of finite element model is presented.In this formula both the result from finite element compu- tation and the measured modal parameter are applied fully.The use of this formula to carry out dynamic modification of the first theoretical model only needs a few of natural frequencies and modes.A system having four degrees of freedom and a practical structure are computed analogically for modifica- tion.Effectiveness is indicated from the result of this method.
