摘要:

采用熔融沉积工艺制造了碳纤维增强聚酰胺齿轮,基于响应面设计研究了层高、填充密度、栅格角度、打印速度和打印温度对磨损寿命的影响,利用灰狼优化算法得到了最优制造工艺。结果表明,层高、填充密度、栅格角度和打印温度是影响磨损寿命的显著因素,打印速度的影响不显著;在10个交互效应中,层高、填充密度、栅格角度和打印温度之间的交互效应对磨损寿命的影响显著;在5个二阶效应中,只有填充密度和栅格角度的二阶效应影响显著;以磨损寿命最大化为优化目标,灰狼优化算法经过100次迭代后,齿轮磨损寿命优化值超过了40 h,得到的最优熔融沉积成型参数为:层高0.2 mm,填充密度89 %,栅格角度45 °,打印速度72 mm/s,喷嘴温度278 ℃,齿轮磨损寿命试验值为41.41 h,与优化结果吻合。

Abstract:

In this study, carbon fiber⁃reinforced nylon gears were fabricated via fused deposition modeling and their wear life was optimized. Utilizing a response surface methodology design, the effects of five key process parameters, including layer height, infill density, raster angle, printing speed, and nozzle temperature, were investigated. The grey wolf optimization (GWO) algorithm was then employed to determine the optimal parameter set for maximizing wear performance. RSM analysis revealed that layer height, infill density, raster angle, and nozzle temperature were significant factors, whereas printing speed had an insignificant effect. Significant interactions were observed between layer height, infill density, raster angle, and temperature. Furthermore, only the second⁃order effects of infill density and raster angle were found to be significant. After 100 iterations, the GWO algorithm predicted an optimal wear life exceeding 40 hours. The corresponding optimal parameters were a layer height of 0.2 mm, an infill density of 89 %, a raster angle of 45 °, a printing speed of 72 mm/s, and a nozzle temperature of 278 ℃. Experimental validation under these conditions yielded a wear life of 41.41 hours, confirming the model's accuracy and the effectiveness of the GWO⁃based optimization approach.
