摘要
通过对往复式切割器工作原理的分析,利用Matlab软件对切割器切割图进行了数值模拟。对影响切割图各区域面积的关键参数进行了仿真计算,得到了提高切割质量、降低功率消耗的较优运动参数和结构参数组合。方差分析结果表明,切割器类型、割刀进距、动刀片刃部高度对空白区和重割区面积影响显著,动刀片宽度、前桥宽度对面积影响不显著。
Cutting pattern of a reciprocating cutter was numerically simulated by using Matlab package. A set of optimized parameters related to kinetics and structure of the cutter were obtained by the simulation. The system constructed by these parameters will achieve a high cutting quality and a low power consumption. The results of variance analysis indicate that the cutter type, feed rate and height knife-edge have big influence on the areas of missing and overlap regions.
