为减小叶片在服役过程中振动导致损伤的问题，以高强度的碳纤维复合材料作为叶片基体，展开叶片的振动特性研究。基于振动分析理论，采用ANSYS Workbench软件对碳纤维复合材料叶片的振动特性进行研究。首先运用Solidworks软件建立叶片高保真模型；其次基于模态分析法得到碳纤维复合材料叶片自由振动的固有频率和各阶振型图，研究叶片的振动响应特性；其次分别在叶片叶尖处施加不同激振力，得到叶片叶尖在各个方向上的振动位移响应；再次根据得到的固有频率，绘制坎贝尔图，分析碳纤维复合材料叶片的振动特性规律。结果表明：叶片的主要振动形式为弯曲振动，随着激振力的增大，各个方向的振幅峰值对应的频率均向左发生偏移。从坎贝尔图中得出叶片在工作转速范围内有3个共振点。

In order to reduce the damage caused by vibration of blades in service, high strength carbon fiber composite was used as blade matrix to study the vibration characteristics of blades. Based on vibration analysis theory, the vibration characteristics of carbon fiber composite blades were studied by ANSYS Workbench software in this paper. Firstly, Solidworks software was used to establish the blade high-fidelity model. Secondly, the natural frequencies and modes of free vibration of carbon fiber composite blades were obtained based on modal analysis, and the vibration response characteristics of blades were studied. Thirdly, different excitation forces were applied to the blade tips to obtain the vibration displacement responses of the blade tips in all directions. Finally, according to the natural frequencies of blades at different speeds, the Cambel diagram was drawn to obtain the vibration characteristics of carbon fiber composite blades. The results show that the main vibration form of the blade is bending vibration, and the frequencies corresponding to the amplitude peaks in all directions shift to the left with the increase of the excitation force. According to Campbell diagram, there are three resonance points in the working speed range of the blade.
