基于ANSYS软件对双闭室复合材料箱型薄壁梁进行模态分析。首先，建立双闭式箱型复合材料薄壁梁的模型，然后，针对两种铺层方式以及不同的纤维铺层角，分别对薄壁梁进行模态分析，揭示复合材料的铺层方式以及铺层角度对双闭室箱型薄、壁梁的固有频率、模态振塑的影响。 The modal analysis of a double-cell thin-walled box beam with composite materials was carried out based on the ANSYS software. First, a model of double-cell thin-walled box beam was created,and then, the modal analysis of thin-walled beam according to two different ply forms and different fiber layer angles was presented, revealing the influence of ply form and ply angle of composite materials on the natural frequency and the modal shape of double-cell thin-walled box beam.
