建立了用于碳纤维酚醛树脂复合材料粘性系数动态识别的二参数模型 ,利用一试件的实测固有频率识别此参数 ,并用其它试件的实测结果加以检验。在识别此参数时还考虑了空气阻尼的影响。分析结果表明此方法是成功的 ,误差达到最小范围
A two-parameter model for the dynamic identification of viscous coefficient of phenolic resin composites was set up. This parameter was identified by the measured natural frequency of a test piece and tested with the test results of other test pieces. The air damping effect is also taken into account when identifying this parameter. The analysis results show that this method is successful and the error is minimized
