介绍一种分析三维编织纤维增强复合材料连杆机构的固有频率、振型和模态阻尼的方法。根据阻尼单元模型 ,采用有限单元法 ,并考虑横向剪切应变的影响 ,导出这些机构动态力学性能参数与复合材料的细观力学结构之间的内在关系
A method of analyzing the natural frequency, mode shape and modal damping of the three-dimensional braided fiber reinforced composite connecting rod mechanism is introduced. According to the damping cell model, the finite element method and the influence of transverse shear strain are taken into account to derive the intrinsic relationship between the dynamic mechanical performance parameters and the meso-mechanics structure of the composite
