摘要： 为了解决生丝张力的测试问题,提出依据声学原理测量生丝张力的方法,利用声发生器在受一定张力时生丝的一端产生机械振荡声波,通过生丝传输到另一端由声接收器接收,测量其输出幅值,发现生丝张力大小与声衰减的关系特性。结果表明,当张力逐渐增加时,通过生丝传输的声强度逐步变大。因此,根据声接收器输出信号的声强度可判断生丝张力的大小。
Abstract: In order to solve the problem of raw silk tension testing,this paper presented a measuring method of raw silk tension using acoustic principle.When the sound wave which is produced by sound generator transmitting through raw silk with some tension form one end to the other,the output amplitude received by sound receiver at the other end was measured,and the relationships between the raw silk tension and acoustical attenuation was examined.The experimental result indicates that when the tension of raw silk increases gradually,the intensity of sound transmitting through it rises.Therefore,the raw silk tension can be determined by the sound intensity signal sent out by the sound receiver.
