一、前言冶金、造纸等工业所绽用的卷取机,多采用恒张力控制或锥形张力控制。为了保证带材张力按照予先给定的规律变化,必须使卷取机在加速和减速的过渡过程中维持给定的张力,以保证产品质量,即厚度公差不超过允许的范围,这样一来必须在加速和减速过程中,给卷取机一个附加力矩——动态补 First, the preface Metallurgy, papermaking and other industries with the winch winder, the use of constant tension control or taper tension control. In order to ensure that the strip tension changes according to a predetermined rule, the coiler must maintain a given tension during the transition between acceleration and deceleration to ensure product quality, ie, the thickness tolerance does not exceed the allowable range Must be in the acceleration and deceleration process, to the coiler an additional torque - dynamic complement
