近期，由我院学生钱海俣为第一作者，教师朱军超为第二作者的论文“多层纤维增强复合材料轴的动力学特性分析（英文）”在Transactions of Nanjing University of Aeronautics and Astronautics上发表。
论文简介如下：
In order to study the dynamic characteristics of multilayer fiber reinforced plastic（MFRP）shaft，thecoupling model of three-dimensional equivalent bending stiffness theory and transfer matrix method is established，andthe influence of thickness-radius ratio，length-radius ratio，layer angles，layer proportion，and stacked approaches on
MFRP shaft dynamic characteristics is investigated. The result shows that the proposed coupling model has high
accuracy in MFRP shaft dynamic performance prediction. The proportion of small-angle layers is the decisive factor ofMFRP shaft natural frequency. With the increase of thickness-radius ratio and length-radius ratio，the natural
frequency of MFRP shaft decreases. The natural frequency of MFRP shaft with the angle layers combination of
±45° and ±90° is smaller compared with the metal shaft no matter in simple/free boundary condition or simple/
simple supported boundary condition.
