摘要
考虑复合材料的各向异性特征与铺层角度、厚度、顺序等因素,建立多层复合材料风扇叶片动力学模型。基于模态分析方法计算复合材料叶片自由振动的固有频率、振型,采用谐响应分析方法研究叶片的振动响应特性,利用Campbell图进行不同转速下的叶片固有特性分析。研究了复合材料大风扇叶片铺层参数对振动特性的影响,结果表明通过调整复合材料叶片的铺层厚度、角度、顺序,可以减少共振点并减小振幅,以达到减振的效果。
Considering the anisotropic characteristics,layup angle,thickness and sequence of composite material,the dynamics model of multilayered composite large fan blade is established.The natural frequency and mode of composite blades are calculated based on the modal analysis method,and the response characteristics of the blades are studied by harmonic response analysis method.The Campbell diagram is used to analyze the natural characteristics of the blades at different speeds.The influence of laying parameters on the vibration characteristics is studied for the composite fan blade.The results show that by adjusting the thickness,angle and sequence of the composite blades,the resonance point and the amplitude can be reduced to achieve the damping effect.
