NUMERICAL CALCULATION AND APPROXIMATE FORMULA OF BUCKLING STRENGTH OF TRACK

In 1967, the adoption of 60 kg rail in the track of the Sanyo Shin Kansen was determined. For this determination, it was considered that the temperature difference corresponding to the buckling strength of the track with this rail would not be different so far from that of the track with 50 T rail. To confirm this, the authors made the calculation program of the buckling strength of track and computed this for every rail in Japan including the new 60 kg rail. Through the investigation of calculated results, it was found that there would be simple approximate formula to calculate the buckling strength of track. This paper contains the calculating method of the buckling strength, calculated results, the composition of the approximate formula and its application.
