摘　　要：针对当前高速织机上经纱张力测量精度低的问题,设计了一种新型的机械数据采集装置。首先从理论分析上确保了该装置的可靠性,当tanθ<0.15时,测量的经纱张力与实际的经纱张力非常接近,消除了装置本身的结构误差;其次,对装置模型进行了数学建模,结合Delphi编程实现了圈形化的用户界面,对经纱张力的数据进行了读取与保存;最后,对两种不同方法(直接、间接)在RIFAJA10喷气织机上进行了实验。实验结果表明,直接测量方法测得的经纱张力比间接测量方法精确,并且其在一个织造周期内比较稳定,受外界干扰较小。Aiming at the low precision of warp tension in the current high speed loom,a kind of new mechanical data acquisition device was designed.Firstly,the reliability of the device was ensured theoretically,when tan θ was less than 0.15,the measured tension was closed to the actual tension,and the error of the structure was eliminated.Secondly,a mathematic modeling was made,and a good user interface was acquired by Delphi to use for reading and saving the data of warp tension.At last,experimental study on the RIFAJA10 air-jet loom was presented with two different methods（directly,indirectly）.The results show that the direct method is better than the indirect method in precision and anti-interference,and it has a stable variation of warp tension in a weaving cycle.
