【摘要】：为了对油气管道内的变形情况进行高精度检测,基于磁敏元件感应弹性检测杆绕轴转角的原理设计了内径检测杆,并研制了新型的内接触式管道测径装置。提出采用二次余弦模型拟合转角与管径之间的数据处理方法,可降低测径拟合残差和提高拟合精度。拟合试验表明,该方法可保证测径拟合残差百分比降至0.5%以下。
[Abstract]:In order to detect the deformation of oil and gas pipeline with high precision, the inner diameter measuring rod is designed based on the principle of magnetic sensing element induction elastic detecting rod around the axis, and a new type of inner contact pipe diameter measuring device is developed. The method of data processing between the fitting angle and pipe diameter by quadratic cosine model is proposed, which can reduce the residual error and improve the fitting precision of the measured diameter. The fitting test shows that this method can ensure that the percentage of fitting residual is less than 0.5%.
