垂直フランジを再現した3次元鉄道車両モデルの地震時の挙動

Key Points

• The study aims to assess the impact of rail-wheel model simplifications on the behavior of a railway vehicle during earthquakes.
• Incorporated simplified and actual cross-sections of rail and wheel models into a 3D vehicle model.
• Compared wheel-axle behavior between models to assess simplification effects.
• Used active suspension systems to evaluate derailment prevention.
• Demonstrated that simplifications do not significantly alter vehicle behavior trends under earthquake conditions.
• Validated the previous research findings on derailment prevention using a more complex model.
