Abstract
The embodiments of the invention provide a curve turning control methods and curve turning control device of a rail vehicle, and the rail vehicle. The curve turning control methods comprises the following steps that transverse force Q acting on a unilateral wheel pair of the rail vehicle is obtained, and vertical force P<internal> acting on an inner side wheel pair and vertical force P<external> acting on an outer side wheel pair are obtained; and the derailment coefficient of the inner side wheel pair and the derailment coefficient of the outer side wheel pair are calculated, and according tothe difference value of lambda<internal> and lambda<external>, whether the rail vehicle has a risk of overturning or not is judged. The curve turning control device of the rail vehicle is used for realizing any one of the curve turning control methods. The rail vehicle comprises the curve turning control device of the rail vehicle. According to the curve turning control methods and curve turningcontrol device of the rail vehicle, and the rail vehicle, the technical problems that when a traditional rail vehicle passes a curve, the working conditions of operation of the rail vehicle are not considered, and whether the rail vehicle has the risk of overturning or not is not judged either are solved.
Description
technical field [0001] The present application relates to the technical field of rail vehicles, and in particular, relates to a method for controlling curve turning of rail vehicles, a device for controlling curve turning and rail vehicles. Background technique [0002] When the curve of the track is laid, the outer rail superelevation method is generally adopted, that is, the outer rail of the track is higher than the inner rail. Rail vehicles widely use air springs as the secondary suspension of bogies. A differential pressure valve is installed between the two air springs of each vehicle. The threshold of the differential pressure valve has been set and is a fixed value. Based on the characteristics of the structure of the existing differential pressure valve, the corresponding threshold can only be set before installation, and the threshold cannot be adjusted regardless of the operating conditions of the rail vehicle. [0003] When a rail vehicle passes through a curve,...
