面向车辆装备战场抢修的FDM技术多参数优化

Multi-parameter Optimization of FDM Technique in BDAR of Vehicle Equipment

针对熔融沉积成型(FDM)技术应用于车辆装备战场抢修时效性和质量难以适应战场环境的问题,利用模糊推理,建立FDM工艺参数与成型件成型时间、尺寸精度、成型件强度之间关系的数学模型;运用多目标函数优化问题的单目标化思想,得到最佳参数组合;通过多因素方差分析确定工艺参数对成型影响的主次顺序,为FDM应用于车辆装备的战场抢修提供指导。

Considering the timeliness of applying fused deposition modeling（ FDM） technique in BDAR of vehicle equipment and the problem of quality difficult to adapt to the battlefield environment,the paper firstly establishes a mathematical model between FDM technological parameter and molding time,dimensional precision and strength of molding part with fuzzy reasoning. Then,it obtains optimal parameter combination with the idea of converting multi-objective optimization problems into single ones. Finally,it determines the primacy influence sequence of technological parameter on molding through multi-way ANOVA,which can provide guidance for applying FDM in BDAR of vehicle equipment.
