摘要

稳定性低是国产印刷机面临的共性问题,印刷滚筒扭振是影响稳定性的关键因素之一。以印刷机压印滚筒作为研究对象,分析了压印滚筒在动力传递过程中的扭矩传递规律:滚筒扭矩因空档等原因存在突变。采用AR(自回归)模型和小波分析相结合,提出了滚筒扭振信号的后处理方法,实现了信号去噪;通过对扭矩测试和数据分析,提取出印刷滚筒的扭振前5阶固有频率65Hz、80Hz、300Hz、375Hz、400Hz;通过与传递矩阵法结果比较,验证了扭振信号处理方法的正确性。研究结果为印刷滚筒的减振与结构优化提供了依据。

Abstract

The low stability is a common problem for the printing machine, the torsional vibration of the printing cylinder is one of the key factors affecting the stability. Torque transfer in the power transmission between impressing cylinders was carried; torque's abrupt happens due to cylinder's gap. With construction of AR (autoregressive) model and wavelet, the torsional vibration data post process method was put forward in order to realize the signal denoising. The cylinder’s natural frequencies 65Hz,80Hz,300Hz,375Hz,400Hz, and moving segment are extracted. Compared with Transfer Matrix method, the torsional vibration process method is verified.The research result is used for printing cylinder’s vibration and structure optimization and guidance.
