摘　　要：以受力条件下复合材料传动轴变形为研究对象。首先,采用理论分析和有限元建模两种方法对复合材料传动轴单向受力变形规律进行了计算和比较。然后,采用有限元方法对复合材料传动轴在多重受力情况下不同材料对称铺层模式下不同铺层角的变形规律进行了求解。单向受力分析结果表明,对称铺层角为45°时有利于提高抗扭刚度,对称铺层角为0°时有利于提高复合材料轴的抗弯及轴压刚度。多重受力结果表明,对称铺层角在(0~19)°区间变形主要受扭矩影响,对称铺层角在(19~90)°区间变形主要受弯矩影响,此外还受选用的复合材料的影响。Taking the deformation of composite drive shaft under load conditions as study object.It firstly,theoretical analysis and finite element modeling methods are used to calculate and compare the deformation law of composite drive shaft under unidirectional press.Secondly the finite element method is used to calculate the deformation law of the composite drive shaft under multiple stresses.The unidirectional stress analysis results showed that the torsion stiffness will be improved when symmetric ply angle is 45°.If the symmetric ply angle is 0°,the bending strength and axial compress stiffness of the composite shaft will be improved.The multiple stress analysis results showed that the deformation in(0~19)°interval ply angle is mainly affected by torque.Differently,when ply angle ranges from(19~90)°,the deformation is mainly affected by bending moment.In addition,the deformation is also affected by the selected composite material.
