| 目的 建立曲面胶印机步进分度系统的三维模型，对步进分度系统进行模态分析和谐响应分析。方法 根据共轭曲面原理建立弧面分度凸轮机构的三维模型，利用Ansys Workbench对步进分度系统进行有限元分析。结果 利用Pro/E建立了步进分度系统的三维模型，其中详细介绍了弧面分度凸轮机构的建模步骤。由模态分析得出步进分度系统的前六阶振型和固有频率，由谐响应分析得出步进分度系统在冲击载荷下的幅频响应曲线，为进一步进行步进分度系统的动态优化设计奠定了基础。结论 曲面胶印机的步进分度系统工作可靠，具有良好的动力学特性，可有效保证印刷质量。 |
| 英文摘要: |
| The work aims to build a three-dimensional model of the stepping indexing system of conical offset printer and conduct modal analysis and harmonic response analysis on the stepping indexing system. The three-dimensional model of globoidal indexing cam mechanism was built according to the principle of conjugation surface. The finite element analysis on the stepping indexing system was carried out by Ansys Workbench. The three-dimensional model of stepping indexing system was built by Pro/E, and the modeling steps of globoidal indexing cam mechanism were introduced in detail. The first six-order vibration model and the inherent frequency were obtained through modal analysis, and the amplitude-frequency response curve of stepping indexing system under impact load was obtained by the harmonic response analysis. The foundation for further dynamic optimum design of the stepping indexing system was provided. With reliable working and good dynamic characteristics, the stepping indexing system of conical offset printer can effectively ensure the printing quality. |
