螺距控制在无缝管超声检测中的应用

Application of pitch control in seamless UT

由于无缝管的广泛应用,对于无缝管自动超声检测的要求越来越高,而螺距控制是自动化探伤中的重要问题之一。保证对钢管管体的全面检测,同时节约检测时间,不发生漏检和重复检测现象是螺距设计的主要要求,为到达上述要求在设计中首先对螺距控制系统建立数学模型,然后对模糊PID控制器进行设计,并用Matlab/Simulink软件进行仿真,最后针对螺距控制进行现场的数据采集与分析。

Due to the extensive application of seamless pipe,the requirement for the seamless UT are becoming stricter and stricter,and the pitch control is the one of the important issues in UT process.The requirements for pitch design are assurance that steel tube can be fully tested and saving testing time,no duplication and undetected pitch.To achieve that,firstly mathematical model for control system should be established,and then the fuzzy PID control algorithm is designed at the same time the simulation is made by Matlab/Simulink software,data is captured and analysised for pitch control.
