摘要 对阻尼测试实验过程中的误差和结构阻尼等效理论误差进行分析.参照国标制备复合材料试件,测量完整和含损伤复合材料悬臂梁的阻尼值,结果表明损伤位置影响模态参数.同时还研究不同激励幅值对阻尼值的影响,该方法在线性范围内得到的阻尼值离散度小. According to damping testing standard,this paper examined the influence factor in experimental damping measurement,analyzed the structural damping equivalent error.Made up of test specimen by using glass fiber and examined the damping value of undamaged and damaged cantilever beam.The results showed that the location of damage was crucial to modal parameters.Anad measured structural damping with different amplitude,the results were stable met the engineering requirements in linear area.
