【摘要】：针对复杂零件生产稳定性问题,提出一种加权网络支持的复杂零件工艺路线稳定性分析方法。利用加工元的概念,构建复杂零件制造过程的加权网络,通过建立多工艺路线决策模型将制造过程中生产成本和制造时间转化为网络的权重,对工艺路线进行初步决策。引入复杂系统脆性理论,通过分析加工元中刀具磨损、设备负荷等脆性事件引起加权网络崩溃的因素,建立加权网络中各个加工元的脆性风险熵,分析加权网络节点脆性风险的指标,预测整个网络中易发生故障的子系统即加工元,同时追溯易导致加工元发生故障的脆性事件,从而得到稳定性高的合理工艺路线。以某航空发动机叶片制造过程为例验证了该方法的正确性和有效性。
[Abstract]:In order to solve the problem of the production stability of complex parts, a method of stability analysis for the process route of complex parts supported by weighted network is proposed. Based on the concept of machining element, a weighted network of complex parts manufacturing process is built. By establishing a multi process decision-making model, the production cost and manufacturing time in manufacturing process can be transformed into the weight of the network, and the process route is initially decided. The introduction of complex system brittleness theory, through the analysis of tool wear, equipment load caused by factors of brittle events processing element weighted network breakdown, establish the brittleness risk entropy for each processing element of the weighted network, weighted network node analysis of brittleness risk index, prediction subsystem fault prone to the entire network in the processing element, at the same time back easily lead to brittle failure event processing element, so as to obtain reasonable process with high stability. The correctness and effectiveness of the method is verified by an example of an aero engine blade manufacturing process.
