摘要/Abstract

摘要： 为优化镐型截齿硬度、耐磨性、冲击性能3项性能指标,对镐型截齿材料实施深冷处理,并取得了良好效果。为得出镐型截齿整机产品最优深冷工艺组,从多目标规划角度,基于QFD模型构建了镐型截齿深冷工艺多目标优化模型,并寻优得出镐型截齿整机产品的最优深冷工艺组为:深冷温度77 K,深冷时间24 h,交变2次。且通过试验验证了此模型的有效性。

关键词: 镐型截齿, 深冷处理, 正交试验, QFD模型, 多目标优化模型

Abstract: For optimization of the conical pick performance indexes including hardness, wear resistance and impact property, deep cryogenic treatment was carried out on the material of conical pick and achieved good results. In order to obtain the optimal conical pick cryogenic process, a multi-objective optimization model of conical pick cryogenic process was proposed based on QFD model from the perspective of multi-objective programming. Then the optimal cryogenic process parameter group is found and experimentally verified as follows: cryogenic temperature of 77 K, cryogenic time of 24 h and alternation number of 2, so that the effectiveness of the model is also verified.

Key words: conical pick cutter, deep cryogenic treatment, orthogonal test, QFD model, multi-objective optimization model
