Currently, there are a limited number of dynamic models available for braided composite plates with large overall motions, despite the incorporation of three-dimensional(3D) braided composites into rotating blade components. In this paper, a dynamic model of 3D 4-directional braided composite thin plates considering braiding directions is established. Based on Kirchhoff's plate assumptions, the displacement variables of the plate are expressed. By incorporating the braiding directions into the constitutive equation of the braided composites, the dynamic model of the plate considering braiding directions is obtained. The effects of the speeds, braiding directions, and braided angles on the responses of the plate with fixed-axis rotation and translational motion, respectively, are investigated. This paper presents a dynamic theory for calculating the deformation of 3D braided composite structures undergoing both translational and rotational motions. It also provides a simulation method for investigating the dynamic behavior of non-isotropic material plates in various applications.

采用Al-Mg及Al-Si两种焊丝分别对SiCp/LD2复合材料进行了MIG焊,利用光镜、电镜及MTS-810试验机对焊缝的组织及性能进行了分析,结果表明,采用Al-Mg焊丝焊接时,熔池中Al-SiC间的界面反应程度均较大,生成了较多的针状Al4C3,且Al4C3的尺寸较大。采用Al-Si焊丝时,MIG焊熔池中的界面反应程度显著降低,仅生成了少量尺寸较小的针状Al4C3;利用Al-Si焊丝还可有效地防止焊缝熄弧处的宏观结晶裂纹。力学性能试验表明,用Al-Si焊丝焊接的接头强度比用Al-Mg焊丝焊接的接头强度高。
