针对联合收获机整机制造品质检测自动化水平不高、缺乏成套检测系统等问题,结合国家相关标准规范和企业实际需求,提出了2种整机制造品质检测方案,即多工位流水线式检测和多功能单元线式检测。通过数字化手段建立了2种整机制造品质检测系统的虚拟仿真模型,包括联合收获机、车间、检测仪器设备、传感器和虚拟工人等,并在Visual Components环境中分别对2种检测系统进行了仿真,对2套检测方案的适用范围、人员作业强度、仪器使用效率等进行了分析。仿真结果表明,多功能单元线式检测系统更适合联合收获机整机制造品质的检测。在建模仿真的基础上,以联合收获机电气系统为检测对象,开发了基于虚拟仪器技术的检测系统,实现了对整机电器工况、起动性能等工作参数的快速检测,提高了检测效率。本研究通过构建数字车间仿真模型为检测工艺评估和系统开发提供了有效的评价方法,进而为制造品质检测优化提供了支撑。

Aiming at the problems in the combine harvester manufacturing industry,including the low automation level of the combine harvester manufacturing quality inspection,the lack of a complete inspection system and other problems,combined with relevant national standards and the actual needs of the enterprise,two kinds of combine harvester manufacturing quality inspection plans were proposed,one was multi-station pipelined inspection system,the other was multi-functional cell-line inspection system.The virtual models of the two combine harvester manufacturing quality inspection systems were established through digital means,the models included combine harvester,inspection equipment and instrument,sensors,workshop and virtual workers.The two inspection systems were simulated in the Visual Components environment respectively to analyze the applicable scope,work intensity,the efficiency of the equipment and instrument,and other workshop operation parameters.And the simulation results showed that the multi-functional cell-line inspection system was more suitable for combine harvester manufacturing quality inspection.On the basis of modeling and simulation,with the electrical system of combine harvester as the object,a set of inspection system based on virtual instrument technology was developed to realize the fast testing of the electrical working conditions,starting performance and other working parameters,which improved the inspection efficiency.The research results show that the construction of digital workshop simulation model can provide effective evaluation methods for inspection process evaluation and system development,thereby providing strong support for manufacturing process optimization.
