摘要
传统的重载传动轴检测是通过应力应变片来进行的,仅能检测轴的局部失效而不能对轴进行整体检测,针对这一问题提出一种基于编码器信号的重载传动轴失效检测方法,在仿真分析中对应力应变片与编码器 2 种检测方式进行对比分析,结果表明编码器信号在重载传动轴整体失效检测中具有优势.在升船机传动轴中进行试验分析,证明了所提方法的可行性.
Abstract
Heavy load transmission shaft is widely used in ship lift,large ship power transmission and other fields,but due to the large torque transmission,and there is alternating torque in the process of mechanical reversing,resulting in heavy load transmission often fracture and other problems,so the failure detection of heavy load transmission shaft was of great significance in the safety of the guarantee and equipment.The traditional detection of heavy load drive shaft was carried out by stress and strain gauges.It was worth noting that the stress and strain detection could only detect the local failure of the shaft,but not the overall detection of the shaft.Firstly,this study compared the two detection methods of stress strain gauge and encoder in simulation analysis to showed the advantages of encoder signal in the overall failure detection of heavy load transmission shaft.Finally,the experimental analysis of ship lift transmission shaft proves the reliability of this method.
