A rail vehicle tilting system, comprising a controller (), a high-pressure air cylinder (), a left side air spring (), a right side air spring (), a left side additional air chamber (), a right side additional air chamber (), a first three-position electromagnetic proportional flow valve (), a second three-position electromagnetic proportional flow valve (), a sensor, a differential pressure valve () and a two-position switch valve (). The left side air spring () is in communication with the left side additional air chamber (); the right side air spring () is in communication with the right side additional air chamber (); the sensor is used for collecting data of a rail vehicle during running, and transmitting the collected data to the controller (); the controller () controls, according to data collected by the sensor, the first three-position electromagnetic proportional flow valve () and the second three-position electromagnetic proportional flow valve (); the differential pressure valve () is used for enabling the left side additional air chamber () to be in communication with the right side additional air chamber (); and the two-position switch valve () is respectively in communication with the left side additional air chamber () and the right side additional air chamber () by means of pipelines. Also disclosed are a rail vehicle tilting control method and a rail vehicle.

A bogie of a rail vehicle includes a frame, which includes two box-shaped longitudinal beam main bodies and a transverse beam main body; a wheelset, which includes an axle box, an axle and wheels mounted at two ends of the axle; a drive system, which at least includes a gearbox and a drive motor. Practice has proved that the two axle boxes arranged on the inner sides of the two longitudinal beam main bodies can reduce a volume by about 10%, and reduce a weight by about 10% to 15%, which can further reduce air resistance, and realize energy saving and emission reduction. The longitudinal beam main body is located on an inner side of a wheel, a span of the two the longitudinal beam main bodies is reduced, and the torsional rigidity of the frame is reduced, which is beneficial to improving a curve passing capacity.

A modeling system and modeling method based on a logical relation, including an operation task integrating module, a task interpreter, a graph layout correcting module, a graph wiring correcting module and a database model increment correcting module, wherein the database model increment correcting module includes a graph increment calculating unit and a model increment calculating unit. The system, through description of the logical relation and based on support of the automatic wiring technology, realizes the graph-model integrated generation of a new grid model of the power system which is based on the description of the logical relation; the grid model is completely defined and modified on 'one net', which is different from the original way that the power system model is established on countless net graphs, thereby helping the grid operation manager to accurately and rapidly establish and modify the grid model of the full system.
