| 摘 要： | 海洋立管作为海洋油气开发的关键设备,在运行期间面临疲劳失效的风险,需要对立管进行疲劳试验。针对海洋立管共振弯曲疲劳试验法,提出基于 S7-300 PLC实现海洋立管共振弯曲疲劳试验装置控制系统的设计思想。采用黄金分割法,寻找确定试件共振频率点；同时,为保障系统能够在该共振频率点稳定运行,采用S7-300 PLC作为核心控制器,结合参数自调节模糊PID控制算法,设计完成疲劳试验装置中转速模糊PID控制器,实现对系统转速的精确控制,使得海洋立管疲劳试验装置控制系统在具有PLC控制灵活、可靠性高等特点的同时,大大提高了其自动化程度。

| Abstract: | During operation marine riser is susceptible to fatigue failure, so riser fatigue tests should be carried out. The design concept of realizing marine riser resonant bending fatigue testing machine control system by using S7-300 are fully described. Golden section method is used to find the resonance frequencies of the specimen. Meanwhile, in order to make the system running at resonant frequencies, the S7-300 PLC is taken as the core controller and combined with the parameters self- adjusting fuzzy PID algorithm to design Fuzzy PID controller. It is not only own the control characteristics of flexible and reliable of PLC, but also greatly improved the automation level of the marine riser testing machine control system. |
