高速探伤车超声波探头自动对中系统研究

Research on the Auto-Alignment System for High-speed Rail Flaw Detection Car

介绍了高速探伤试验车的超声波探头自动对中系统,该系统采用了基于差动变压器原理的对中传感器和电液伺服对中作动器。

In this paper,a lateral auto-alignment system for a prototype high-speed rail flaw detection car was presented.The alignment sensor based on the principle of differential transformer and the alignment actuator with an electro hydraulic servo were used in the system.The test result proved the system was suitable for the high-speed rail flaw detection car.
