듀얼 레일 형상에 적합한 철도차량의 차륜 형상 설계

초록

When a wheel profile of a train-tram is designed, both train and tram tracks should be considered. This studydesigned a wheel profile that enables high-speed driving(200km/h) on the train track and low speed driving onthe tram track with multiple sharp curves. The study used the approximation optimization method to reduce costand time, used the sequential quadratic programming method as the optimized algorithm, and the centralcomposite design and response surface method as an approximate model. The optimized wheel shape based onthis approximation optimization method reduced wear of the initial wheel showed a better performance in termsof derailment and lateral force.
