Problems solved by technology

However, limited by the spring and damping effect between the car body and the bogie, the car body will not completely deflect freely according to the magnitude of the centrifugal force. When the actual deflection angle cannot meet the deflection angle required to completely balance the centrifugal force, the resulting The unbalanced centrifugal acceleration will be borne by the passengers, and since the suspended monorail vehicle is suspended in the air, the unbalanced centrifugal acceleration effect on the human body will be greater than that of the traditional wheel-rail, so it is limited The comfort index in the relevant railway design codes is generally met by reducing the speed of the train passing through the small-radius curve section, so how to avoid excessively reducing the speed of the train passing through the curve, and at the same time effectively reduce the unbalanced centrifugal acceleration to improve ride comfort. Comfort index, the research focus of suspended monorail trains

Abstract

The invention discloses a control system for improving riding comfort of a mounted monorail train. According to the control system, the tilting amplitude of a train body can be actively corrected whenthe train runs in a curved section or a straight section, and the tilting degree of the train body can be rechecked through unbalanced centrifugal acceleration after tilting is corrected, so that thereal-time offset of the unbalanced centrifugal acceleration after the effective compensation of the lateral declination of the train body is achieved, the riding experience is effectively improved, the passenger comfort is directly improved, the excessive reduction of a train passing speed under a small radius curve is avoided, the adaptability to the line, weather conditions and other factors isimproved, different tilting instructions can be given for different carriages, and then each carriage completes a corresponding tilting action to ensure the effect that the carriages at different positions all can offset the influence of the unbalanced centrifugal acceleration.

Description

technical field [0001] The invention relates to the technical field of suspended monorail trains, in particular to a control system and an implementation method for improving riding comfort of suspended monorail trains. Background technique [0002] As a new domestic rail transit system in recent years, the suspended monorail can effectively improve the utilization rate of urban space because its car body is suspended under the track beam, and it is not restricted by terrain conditions, which can make up for the shortcomings of urban three-dimensional traffic , It complements the planning of urban viaducts and so on. [0003] When the suspended monorail train passes through a curved section, since the track does not have superelevation, its unique structure determines that the vehicle completely relies on the tilt of the car body to balance the centrifugal acceleration. However, limited by the spring and damping effect between the car body and the bogie, the car body will n...
