激振式纤维线密度测试中影响参数的研究

激振式纤维线密度测试仪器近年已扩大使用，但不少仪器在由共振频率计算纤维线 密度时，只按理想的、有质量无刚度柔韧线弦振动方程，忽视了纤维模量、纤维密度、纤维 截面形状的影响，测试结果误差较大．作者导出了考虑纤维刚度的激振方程，并得到了新 的由共振频率及各参数计算纤维线密度的公式．

Influential factors of testing fiber linear density with disturbance resonator

The fiber linear density tester with disturbance resonator was used widely for these years. But there' s a larger error for the fiber linear density in computational process,which is due to negligence of some influential factors,such as fiber modulus,fiber density and fiber cross section shape. According to the inference from vibration equation, a new equation was setted in view of the resonant frequency and influential factors.
