几种铺层方向复合材料层合板的动态特性试验研究

本文对0°1]_■、±45°]_■和90°]_■三种铺层方向的复合材料悬臂梁进行了自由振动和共振试验,这两种方法得出的基频和衰减系数基本吻合.基频的理论计算值与实验值基本一致.

Dynamic Behavior of Laminates with Ply Lay-up in Various Directions

Cantilever beam specimens made of laminates with ply lay-up in are subjected to free vibration and resonance tests. From these tests, it is found that the coefficients of decrement are consistant; and the fundmental frequencies are also consistant and basically agree with those computed by theoretical approach.
