电子送经系统经轴线速度计算公式的探讨

A probe to the calculation model of the warp beem linear speed of electronic let-off system

通过观察分析,对无测量反馈装置的电子送经系统的经轴线速度计算公式提出疑义。针对目前研究电子送经计算公式的相关文献及Karl Mayer公司的最新资料都将经纱视作刚体来计算瞬时送经速度,以此作为控制瞬时送经量的指令,指出这种计算公式存在计算误差,其误差属送经系统中固有的微量误差,无法通过合理的操作方法给予消除。并进一步对该误差作了定性分析,认为其定量分析十分繁复,建议立题研究。

Based on the observation and analysis, the the warp beam instantaneous linear speed controlled by roller device. According to the document concerning present and the latst information of Karl Mayer, the researcher raised doubts about the calculation model of the electronic let-off system equipped with no feed back the study of calculation model of electronic let-off at warp ends are regarded as some stiff material when calculating the warp beam let-off instantaneous speed which is used as basis for sending the signal to control the instantaneous warp beam let-off. It is pointed out that the tolerance resulting from this calculation belongs to a micro tolerance inherent from this let-off system and can not be corrected by optimizing its operation. And a qualitative analysis of this tolerance is done in this article. However, its quantitiative analysis is very complicated and further research as an individual subject is suggested.
