摘　　要：在织造和染整加工过程中,织物沿纵向连续运动,因此织物的振动性能比较复杂,它是典型两维纵向运动,而涉及两维纵向运动物体振动特性研究的文献较少。因此对纵向运动织物的自由振动进行了理论分析,给出了其固有频率的计算公式,并对固有频率的几个影响参数进行了讨论。A fabric moves continuously along machine direction during weaving, dyeing and finishing processes. Its dynamic behaviour is very complex during processing. The fabric movement is a typical two-dimensional longitudinally moving and the references about this topic are few. Analysis for transverse free vibration of a longitudinally moving fabric is put forward here, with the calculating formula for natural frequencies of the fabric being introduced. Meanwhile the effects of several paremeters on the first order natural frequency are also discsssed.
