对复合材料 FRP 板的自由振动进行了实验和数值相结合的研究。使用冲击激励进行模态测试，以确定从中提取模态参数的相应频率响应函数。还开发了基于使用等参元的计算机代码的有限元方法来确定模态特性。商业有限元包（NISA）已用于验证当前代码。比较了理论结果和实验结果，并调查了差异的原因。发现实验数据与数值预测有很好的相关性。
A combined experimental and numerical study of the free vibration of composite FRP plates has been carried out. Modal testing has been conducted using impact excitation to determine the respective frequency response functions from which the modal parameters are extracted. A finite element method based computer code using an isoparametric element has also been developed to determine the modal characteristics. A commercial finite element package (NISA) has been used to validate the present code. Both theoretical and experimental results are compared and causes of discrepancies are investigated. The experimental data were found to correlate well with the numerical predictions.
