摘　　要：针对舰船复合材料传动轴减振机理尚不清晰的问题,文中构建了某舰船复合材料轴仿真模型,基于功率流法分析了复合材料轴振动能量传递特性,并在此基础上进一步探究了钢法兰-复合材料刚柔耦合界面匹配参数和轴段内复合材料铺层方式对振动能量传递的影响规律。最后通过复合材料传动轴模态试验和振动传递试验验证了仿真模型的准确性。结论如下:刚柔耦合界面对于振动能量抑制有着显著作用,其振动能量的传递随接触面积的增大而降低,而弹性模量比仅影响传动轴固有频率;随着铺层角度的减小及铺层数量的增加,复合材料轴段隔振性能逐渐增加。Here,aiming at the problem of vibration reduction mechanism of warship composite transmission shaft being still unclear,the simulation model of a certain warship’s composite shaft was built.Based on the power flow method,its vibration energy transfer characteristics were analyzed.Then,effects of matching parameters of steel flange-composite rigid-flexible coupled interface and composite material laying form of shaft segment on vibration energy transfer were further explored.Finally,the correctness of the simulation model was verified with modal tests and vibration transfer tests of composite transmission shaft.It was shown that the rigid-flexible coupled interface has a significant action on vibration energy suppression;vibration energy transfer decreases with increase in contact area;elastic modulus ratio only affects natural frequencies of the transmission shaft;with decrease in laying angle and increases in layer number,vibration isolation performance of composite shaft segment gradually grows.
