摘要
针对非晶带材在铁心卷绕成型过程中因卷绕张力不均匀而产生的撕裂、折叠等问题,提出了基于谐波平衡法的卷绕张力控制方案。首先,根据铁心的外形特点,构建了铁心卷绕的动态模型,并利用麦克劳林级数与傅里叶级数对模型进行简化;然后,采用谐波平衡法控制送带速度无滞后跟踪卷绕速度,从而实现对卷绕张力的控制。仿真和实物测试结果表明,该控制方案能实现送带速度在有限次谐波内无差跟踪卷绕速度,使卷绕张力稳定在设定值,同时具有良好的抗扰动性能,对非晶变压器铁心的恒张力立体卷绕具有指导意义。
To solve the problems of tearing and folding caused by uneven winding tension of amorphous strip in the winding process of core,the winding tension control scheme based on the harmonic balance method is proposed.Firstly,the dynamic model of the core winding is established according to the shape structure of the core,and the model is simplified by using the Maclaurin series and Fourier series.Then,the harmonic balance method is used to control the strip feeding speed,so that the winding tension is controlled through the strip feeding speed tracking the winding speed without delay.The simulation and physical test results show that the control scheme can maintain winding tension stable at the set value through the strip feeding speed tracking the winding speed without error within the finite harmonic,and has excellent anti-interference performance,which has guiding significance for constant tension three-dimensional winding of the amorphous transformer core.
