基于AMESim与ADAMS联合建模的轧机厚控系统仿真
|
摘要
为了全面研究轧机液压厚控系统动态特性,建立直观真实的虚拟轧机模型,提出基于AMESim和ADAMS联合建模的仿真方法。在ADAMS中构造轧机实体刚柔耦合动力学模型,实现了轧机的负载特性研究;在AMESim中建立液压系统物理模型,实现了液压伺服系统精确建模和分析,两者通过接口实现数据交换,保证了液压系统模拟的准确性和负载系统模拟的真实性。通过联合仿真模型得到了系统实时响应以及出口板厚实时数据,将模型仿真输出数据与实测数据进行比较,证明仿真模型能准确体现系统动态响应,并能体现机械部件在载荷下弹性变形和板厚实时输出情况。
In order to research the dynamic property of rolling mill gauge control system in the round,a visible accurate rolling mill model was established,the co-simulation method was proposed based on AMESim and ADAMS joint modeling. The rolling mill entity flexible coupling dynamics model was constructed in ADAMS,which achieved the study of rolling mill load characteristics. The physical model of the hydraulic system was established in AMESim,which achieved a precise modeling and analysis to hydraulic servo system. Both of them implemented data exchange through the interfaces,which ensured the accuracy simulation of the hydraulic system and the authenticity of load system simulation. The system real-time dynamic response and real-time data export thickness were obtained through the co-simulation model. By comparing the simulation output data with measured data,it can be concluded that the model can simulate the dynamic response accurately and can reflect the elastic deformation of mechanical components under heavy loads and the thickness of outlet strip.
