| 目的 研究瓦楞辊齿顶动态包角变化规律，优化瓦楞辊的楞型参数。方法 建立瓦楞纸板成型过程中瓦楞辊的齿顶动态包角方程，选取3组实际楞型参数，对每一个不同的转动角度所对应的动态包角进行计算，并用Matlab求解，以确定在一个啮合周期内包角的变化规律及其影响参数。结果 不同楞型参数瓦楞辊在工作时的总包角变化规律不同，且该变化规律与实测工况一致；瓦楞辊齿顶动态总包角的突变会导致瓦楞纸成型过程的振动和噪声明显增大，从而降低成型质量、减短机器寿命。结论 建立的动态总包角方程符合瓦楞纸板的实际成型过程，为瓦楞辊的优化设计及误差分析奠定了理论基础。 |

| Abstract: |
| The paper aims to study the variation rule of the top arc dynamic envelope angle of corrugating roller, and optimize parameters of corrugated roller. In this paper, a dynamic enveloping angle equation of corrugating roller in forming of corrugated board was established to calculate the dynamic wrap angle corresponding to each different rotation angle with Matlab, to determine the variation rule of the angle of inclusion in a meshing period and its influence parameters. The enveloping angle of corrugated rolls with different corrugated shape parameters had different changing rules during operation, and the changing rules were consistent with the measured working conditions. The abrupt change of dynamic wrapping angle would cause the vibration and noise of the corrugated paper forming process, increase obvious sly, reduce the forming quality and shorten the machine life. The dynamic total envelope angle equation established in this paper is consistent with the actual forming process of corrugated board, which lays a theoretical foundation for the optimal design and error analysis of corrugated rolls. |
