综框模态特性对综框运动的影响

在喷气织机的开口系统上测量了综框的加速度时间历程,并把数据转换到频域,测量范围定在0～200HZ。测量结果表明综框横振动模态是影响综框振动和产生故障的主要因素,建议综框应改刚性结构为弹性框架,这样将改善综框的动态性能和延长使用寿命。

Heald Frame Vibration Response Due to the Modal Structure

The acceleration waveforms of the heald frame have been measured on the shedding system of the air-jet weaving machine and transformed to the frequency domain, these freq uency spectra have been averaged over selected bandwidths between zero and 200 Hz. The results indicate the lateral vibration modal have an significantly effect on the shaft vibration and failure, the heald frame should be clastic structure is suggested. This knowledge is crucial for improving the dynamic performance and durability of heald frame.
