Abstract :
The suitability of catenary directly affects the performance of current collecting between the pantogragh and catenary, in a general way whether the catenary has large unsuitability, namely hard spot, is depended on which if the maximum associated with the vertical impact acceleration of pan-head within each segment is larger than a given threshold, it will be calculated by fuzzy c-mean algorithm. Linear regression is used to equal the speed, which eliminates the influence of speed on the maximum associated with the vertical impact acceleration of pan-head. The result shows that threshold of the hard spot calculated by FCM algorithm is reasonable.
