| Abstract: | Because the operation of spectrum analysis technology is simple and fast,it is an important method of engine wear condition monitoring.In this paper,the data fusion system is built based on engine wear character and recognition frame.The believing region and wear states are gained by wear quantity data fusion method and wear speed data fusion method and wear quantity combined with wear speed data fusion.A group of practice shows that spectrum data fusion can heighten the recognizing correctness,and it is an ideal method of engine wear condition monitoring. |
