摘要
本文采用有限元分析的方法,研究了压气机复合材料叶片的建模以及铺层参数对复合材料叶片的影响。在ANSYS平台中,采用ACP模块对复合材料叶片进行建模,通过对比传统TC4叶片的建模方法验证了复合材料叶片建模方法的准确性。研究了铺层角度与铺层厚度对复合材料叶片的强度影响规律。研究表明:随着铺层角度的增加,复合材料叶片的最大变形呈现先减小后增大的趋势,但叶片的最大等效应力逐渐增大。铺层厚度改变导致叶片变形与应力的变化不超过5%。因此,在设计复合材料叶片时应将设计的着重点放在铺层角度上。
In this paper,the finite element analysis method is used to study the modeling of the compressor composite blade and the influence of the ply parameters on the composite blade.In the ANSYS platform,the ACP module is used to model the composite blade,and the accuracy of the composite blade modeling method is verified by comparing the modeling method of the traditional TC4 blade.The influence law of ply angle and ply thickness on the strength of composite blade was studied.The research result shows that with the increase of the ply angle,the maximum deformation of the composite blade first decreases and then increases,but the maximum equivalent stress of the blade gradually increases.Changes in ply thickness result in blade deformation and stress changes of no more than 5%.Therefore,the design emphasis should be placed on the ply angle when designing a composite blade.
