摘要

摘要: 可靠并且完备的装配模型是装配序列评价和优选的前提;赋时Petri网为装配序列的优化选择提供了一种有效的工具,但前提是装配赋时Petri网模型包含可靠并且完备的可行装配序列。本文给出了一种基于赋时Petri网的装配建模方法。该方法通过逐层分析所有的可能装配操作保证装配模型的完备性,通过判断局部装配几何可行性保证装配模型的可靠性。最终建立的装配赋时Petri网模型为进一步的装配序列评价、优化和选择提供了支撑。

Abstract: Complete and credible assembly model are imperative in assembly sequence planning. Timed Petri net is an efficient graph-based mathematical tool suitable to optimize and select assembly sequences based on a complete and credible assembly model. An approach for estimating assembly timed Petri net model is proposed. In this ap-proach, all possible assembly operations are analyzed and local geometrically feasibility of subassemblies is esti-mated layer by layer to guarantee the reliability of assembly model. The established assembly timed Petri net model can provide data support for the evaluation, optimization and selection of assembly sequences.
