蜂窝材料锯切角度建模与优化设计

Modeling and optimization design of cutting angle for honeycomb material

针对蜂窝体脱硝催化剂材料脆性较高,严重影响锯切效率的问题,对蜂窝体材料锯切负载、锯切角度和锯切能耗等方面进行了研究,对蜂窝材料的结构不连续特性进行了归纳,基于经典锯切负载建模理论和大量锯切实验负载分析,提出了通过最优锯切角度的设计来实现高效锯切。以锯切功为比较对象,建立了以锯切角度为基础锯切负载模型,得出了最优锯切角度,并进行了多种角度的锯切实验。实验结果表明:锯切角度45?对应的锯切负载明显小于其两侧的锯切负载;同时,从锯切负载的幅值分布来看,锯切角度为45?的锯切负载波动明显小于35?和55?时的幅值,说明其稳定性也最优。

Aiming at solving sawing efficiency problems of the honeycomb denitration catalyst material, which caused by its high brittleness, the sawing load, sawing angle and sawing energy were studied. The structure discontinuity characteristics was reorganized and summarized. Based on classical sawing load modeling theory and a large number of sawing experiment, a design of the optimal sawing angle was proposed to realize high efficiency sawing. The sawing load was taken as the comparison object. The sawing load model based on the cutting angle was established, and the optimal sawing angle was obtained. The sawing experiments were carried out at various angles. The results indicate that the sawing load of 45？ was obviously less than that of both sides. At the same time, from the perspective of the sawing load amplitude distribution, the sawing load fluctuation of 45？ was obviously less than the value of 35？ and 55？, which means its has a optimal stability.
