摘要:
为了准确预测纤维复合薄板的振动响应,本文采用了多层次修正技术,考虑了基础激励的影响,建立了该类型复合薄板的理论模型,并明确了基于多层次修正的基础激励下复合薄板振动响应预测原理。结合测试获得的固有频率、振型及频域响应等实验数据,在第一层次修正环节对理论模型中复合薄板的长度、宽度和厚度等尺寸参数进行修正;在第二层次修正环节,对纤维纵向、横向弹性模量、剪切模量和泊松比进行修正,在第三层次修正环节,则对不同纤维方向的损耗因子进行修正,进而提出了复合薄板振动响应的预测流程。并以TC300碳纤维/树脂基复合薄板为例,搭建了振动响应测试系统,并对预测结果进行了验证。验证结果表明,预测获得的共振及非共振响应结果与测试结果的误差最大不超过15%,处于误差允许的范围内,进而验证了所提出的预测方法的正确性。
