轮盘低循环疲劳试验器自动控制系统的开发

Development of Automatic Control System for Disk Low Cycle Fatigue Test Rig

利用高速旋转试验设备进行轮盘低循环疲劳试验是开展轮盘疲劳寿命及损伤容限性能研究的有效手段。为确保此类试验器能够长时间稳定运行,开发了1套可靠的、无人值守的自动控制系统,以触摸屏为人机接口(HMI)完成试验参数的设置,以可编程逻辑控制器(PLC)为主站控制设备启停及转速循环,监测系统采用工控机(IPC)完成数据显示和保存,并采用第3方控件实现IPC和PLC的串口通信。测试结果表明:该控制系统稳定性高、可靠性好,完全满足设计要求。

The disk Low Cycle Fatigue（LCF） test was conducted using high-speed spinfacility that was a very effective equipment for the disk LCF life and damage tolerance. In order to ensure that such a rig was stable oper- ation for a long time, the stable and unattended automatic control system was developed. Touch screen was used for Human Machine In- terface （HMI） to complete the set of testing parameters, and Programmable Logic Controller （PLC） was used as the master station to control start-stop and speed loop, the monitoring system used IPC was responsible for data display and storage. Third-party component was uti- lized to realize serial communication of IPC and PLC. Testing results show that stability and reliabihty of the control system are well, and fully meet the design requirements.
