钢丝绳金属截面积损失型损伤检测传感器设计及仿真分析
|
摘要
为了开发一种能够精确定量检测钢丝绳金属截面积损失(LMA)型损伤的传感器,根据主磁通量检测原理,分别对传感器主磁回路、励磁结构、检测元件和信号处理部分进行设计,得到以感应线圈作为检测元件的钢丝绳LMA型损伤检测传感器;通过理论计算对模型可行性进行验证,并使用MATLAB软件对3种直径待测钢丝绳分别进行仿真分析,得到钢丝绳中磁通量与截面积损伤量之间的一般联系。结果表明:钢丝绳缺陷使钢丝绳中的主磁通量减少,磁通量变化情况与损伤程度基本呈线性关系;当待测钢丝绳直径为16～22 mm时,直径越大,则磁通量相对于损伤程度的变化程度越大,线性度越差。
To develop a sensor that could accurately and quantitatively detect the loss of metallic cross-sectional area(LMA) damage of wire ropes,the magnetic circuit,excitation structure,detecting element,and signal processing part of the sensor were designed respectively based on the principle of main flux,and a wire rope LMA damage detection sensor with induction coil as detection element was obtained. The feasibility of the model was verified through theoretical calculation,and the MATLAB software was used to simulate and analyze wire ropes with three kinds of diameters. The generally connection between the magnetic flux and the loss of cross-sectional area in wire ropes was obtained. The results show that the defect of wire ropes reduces the main magnetic flux in wire ropes,and the change of the magnetic flux is linear with the damage degree. When the diameter of the wire rope is in the range of 16 mm to 22 mm,the larger the diameter is,the greater the variation degree of magnetic flux is than the damage,the worse the linearity is.
