APPARATUS FOR ESTIMATING LATERAL FORCES OF RAILROAD VEHICLES |
摘要 |
The present disclosure relates to an apparatus and a method for estimating a lateral force applied to a bogie due to contact between a wheel and a rail when a railroad vehicle drives in a curved section, the apparatus including: a lateral velocity estimation observer configured to calculate a lateral velocity estimate by estimating a lateral velocity based on a vertical acceleration, a lateral acceleration, a yaw velocity, and a wheel angular velocity of the railroad vehicle; and a lateral force estimation observer configured to calculate a lateral force estimate, by estimating a lateral force applied to a bogie of the railroad vehicle based on a steering angle of the railroad vehicle, a vertical force applied to the railroad vehicle, and a lateral velocity estimate calculated by the lateral velocity estimation observer. |
