大变形复合材料柔性梁静、动特性的试验研究

Experimental Study of Static and Dynamic Behaviors of Composite Beams under Large Deflection

本文对两种铺层的复合材料柔性梁进行了静、动特性的试验研究，重点研究了挠度、结构耦合、梁的根部安装角等对变形、固有频率的影响。得出的结论有助于直升机旋翼桨叶的设计和发展。

Experimental investigation of static and dynamic behaviors of flexible composite beams is made to study the deformation and natural frequency of beams affected by deflection,structurally coupled property and root angle.The results are useful for designing composite rotor blades under large deflection and for developing and verifing the analytical model of composite blades under large deflection.
