摘要
分解与重组基于特征的零件设计与工艺设计的并行过程 ,实现了基于特征的零件设计与工艺设计的实时并行 ;通过增加设计小循环次数来减少设计大循环次数 ,从而减少设计的反复过程和缩短产品开发周期。建立了基于时间Petri网零件设计与工艺设计的实时并行过程模型 ,通过计算设计循环时间 ,定量分析了实时并行过程的时域性 ,理论分析与实际基本一致 ,为实施产品实时并行设计方法提供了可靠的理论依据。
The concurrent process of design and process planning of parts is decomposed and reorganized based on feature. The real-time concurrence of design and process planning of parts is implemented. The small-cycles are increased and large-cycles are decreased in the concurrent design in order to decrease design time. The real-time concurrent process model of the design and process of parts is established based on time Petri net. The time performance of real-time process is analyzed, and theory analysis is accorded with the practice. The sound theory proof is provided for realizing the real-time concurrent design.
