HUNTING PROBLEM OF HIGH-SPEED RAILWAY VEHICLES WITH SPECIAL REFERENCE TO BOGIE DESIGN FOR THE NEW TOKAIDO LINE

This paper describes the preliminary experiment on hunting by means of a model vehicle; the hunting tests of an experimental bogie and the prototype bogie at the rolling stock testing plant; a considerable amount of various hunting calculations carried out in the design stage; running test, with casual hunting observed, of the prototype bogies on the test track section of the new Tokaido line; and the construction of a bogie finally designed--and gives a number of major results with some discussion on the points to be considered. Elaborate running tests of six prototype cars were carried out on the test track section of the new Tokaido line. In designing this bogie, special attention was paid to the following two points to prevent hunting: (1) Mode of axle-box support and its stiffness: (2) Combination of frictional and elastic restoring force against bogie rotation. According to the running test at 246 km/h this bogie exhibited a very high running stability.
