分岐器構造を考慮した走行解析ツールの開発

抄録

In this study, we constructed a train running analysis model in consideration of only the linear shape of turnouts in order to evaluate train running safety on turnouts easily. Moreover, we also constructed an automatic creation tool of a simple model for creating simple turnout models automatically by setting conditions for determining the linearity of turnouts. We could create arbitrary shapes of turnouts easily and evaluate train running safety on turnouts in advance by using the tool. We created a turnout model and carry out a trial calculation and compared the calculation result with the result of past running tests. As a result, we found that the calculation result and the running test result were roughly equivalent. From this, we could utilize the train running analysis model and the automatic creation tool for the investigation of the new structure of turnouts. In the future, we would expand the tool by adding such input items on excess width of the track gauge and track irregularity.
