THOR网在机器人装配系统装配质量预测和分析中的应用

Modelling and Predicting of the Quality of a Robotic Assembly System Based on THOR Net

装配质量对产品的性能和可靠性有直接的影响 .基于一类高级的 Petri网—— THOR网 ,对机器人装配系统装配质量的预测进行了研究 ,提出了系统分析装配质量的模块化建模方法 .该方法可以对各种装配策略和手段与装配质量间的关系进行研究 ,是实现机器人装配系统装配质量评价与控制的有力工具 .

Assembly quality has direct influence on the performance and reliability of products. There are various factors influencing the assembly quality in robotic assembly systems. The key to the evaluation and control of assembly quality is the description of relations between influencing factors and assembly quality from a system perspective. Based on THOR net, a new approach for analyzing and predicting the assembly quality of robotic assembly systems was proposed which can be applied to almost all kinds of robotic assembly systems and is the base of systematic research of different assembly strategies and operations.
