Research on Detection Method of Locomotive Wheels’ Ultrasonic Testing Signal
摘要
Abstract
With the reason that domestic locomotive wheel flaw detection system has long been a lack of efficient and practical means to extract the ultrasonic flaw signals in noisy environments,suggest that the signal can be identified in effect by combined signal detection methods,which include wavelet transform method and cubic spline interpolation method. Through the platform to send commands to per-form signal processing,so the signal can be seen by the A-Scan based on the C# software platform. Simulation results illustrate that the de-noising's effect is obvious. With the fast and accurate signals,the methods can greatly improve the defect detection rate. In addition, mixed programming of C# and MATLAB with the complementary strengths of the different building environment can improve operational efficiency.关键词
