基于多体动力学的热轧卷取机踏步系统联合仿真研究

针对某钢厂热轧1700生产线卷取设备的特点,在ADAMS环境下进行了动力学仿真,并用AMESim建立了该卷取设备踏步系统的模型,实现了液压、控制与机械系统动力学联合仿真研究。在所建立多机耦合模型基础上,准确计算出了助卷辊的踏步轨迹、液压缸的负载变化规律和液压缸的油压变化规律,讨论了不同参数对踏步控制系统的影响。结果表明采用液压伺服控制系统其控制精度和响应时间是可以保证的,为卷取机的设计以及技术改造提供了有效的理论依据。

Co-simulation Research of Automatic Jumping Control System of Hot Strip Mill Coiler Based on the Multi-body Dynamics

The dynamic model was established with the tool of ADAMS software for Coiler on the 1700 product line of a steel factory and AJC(Automatic Jumping Control)system model of wrapper equipment was built by AMESim software.Then the dynamic co-simulation of hydraulic,control and mechanical system was achieved.Based on the multiphase-match model, the jumping trace of the aid-roll,changing rules on loading and pressure of hydraulic cylinder were worked out;effects on different parameters of AJC system were also discussed.Conclusions show that the hydraulic servo control system can achieve the required accuracy and speediness;a valid theoretic basis for design and technique alteration of coiler is provided too.
