中文摘要:
      目的 研究瓦楞辊在复杂工作应力条件下的中凸度优化设计。 方法 通过理论力学的方法, 建立相应的上、下瓦楞辊的中凸度数学模型, 推导出中凸曲线方程。 对优化后的瓦楞辊进行力的加载和几何约束等边界条件, 建立有限元模型, 并且使用 Ansys 软件进行模拟仿真, 将优化前后的中凸值和 6 对啮合的瓦楞辊间隙值进行比较。 结果 优化后的上瓦楞辊中凸值比优化前最大降低了31.1%, 下瓦楞辊中凸值比优化前最大降低了 43.7%; 6 组啮合的瓦楞辊, 优化后比优化前的中凸值间隙减小, 说明优化后的 6 组瓦楞辊的自身受力情况较为均匀 , 生产出的瓦楞纸板质量更好, 并且瓦楞辊之间的阻力减小, 延长了瓦楞辊使用寿命。 结论 通过对瓦楞辊中凸曲线进行优化设计, 将上瓦楞辊制成向下凹的形状, 同时将下瓦楞辊制成向上凸的形状, 根据有限元仿真的数据对比得出研究方法是合理可靠的。
英文摘要:
      Objective To study high speed corrugated roller work in complex stress conditions in the dynamic behavior degree of camber. Methods By methods of theoretical mechanics, the mathematical model of the corresponding upper and lower corrugator roll was established, and the corresponding convex curve equation was introduced. Ansys was used to simulate the working state of the corrugated roller and establish finite element model to analyze force on the corrugated roller load and geometric constraints. The convex values and 6 groups of corrugated roller gap values were compared before and after optimization. Results The results showed that the convex value of the upper corrugated roller was maximally reduced by 31.1% after optimization, and the convex value of the lower corrugated roller was maximally reduced by 43.7% after optimization. For all 6 groups of mesh corrugated roller, the convex clearance was decreased after optimization, indicating that the force on the corrugated roller itself was more even after optimization, the corrugated board produced was of higher quality, and the resistance between the corrugated rollers was decreased, the service life of the corrugated roller was prolonged as well. Conclusion Optimization design of the convex curve of corrugated roller led to the concave shape of the upper corrugated roller and the convex shape of the lower corrugated roller. Data comparison based on the finite element simulation showed that the research method was reasonable and reliable.
