Abstract
The invention relates to a method for eliminating coupling vibration of an EMS type magnetic-levitation train track. The method for eliminating coupling vibration of the EMS type magnetic-levitation train track relates to EMS type magnetic-levitation train track levitation electromagnets and multiple gap sensors, and the position of the arithmetic mean value of the multiple gap sensors is similar to or the same as the position of resultant force of the magnetic force generated by the levitation electromagnets. The method for eliminating coupling vibration of the EMS type magnetic-levitation train track has the advantages that important reasonable factors of coupling vibration of the EMS type magnetic-levitation train track are eliminated under the condition that cost is not increased almost; due to the fact that the possibility of vibration is lowered, design difficulty and debugging difficulty of a vehicle levitation system including a levitation control system are lowered; due to the fact that the possibility of vibration is lowered, the levitation performance of a vehicle is further improved; the defect that in the prior art, in order to lower the possibility of vibration, the rigidity of line track beams needs to be extremely high and is far higher than the rigidity required by ordinary wheel track type rail transit by one eight hundred is overcome; the construction cost of line projects is greatly lowered.
Description
Technical field
The present invention relates to and a kind ofly can fundamentally solve because gap sensor is arranged on one end of levitating electromagnet, its position, the position of making a concerted effort of the electromagnetic force produced with levitating electromagnet does not overlap, thus the displacement data of the track girder making gap sensor collect and the track girder actual displacement produced under electromagnetic force is inconsistent, cause control system carry out suspend control according to off-square displacement data and cause the method for the elimination EMS type magnetic-levitation train track coupling vibration of vibration, belong to EMS type magnetic-levitation train track control structure and control method manufacture field.
Background technology
Prior art is installed on one end of levitating electromagnet due to gap sensor, the position of making a concerted effort of the electromagnetic force produced with levitating electromagnet does not overlap, thus the displacement data of the track girder making gap sensor collect and the track girder actual displacement produced under electromagnetic force is inconsistent, control system carries out suspend control according to off-square displacement data, thus cause vibration, Fig. 3.Figure grade 1 is levitating electromagnet, and 2 is gap sensor, and 3 is the bogie truck of vehicle, and 4 is track.
Summary of the invention
Design goal: avoid the weak point in background technology, designing a kind of is exactly position and the quantity of reasonable Arrangement gap sensor, the position of making a concerted effort of the electromagnetic force that its synthesising position is produced close to levitating electromagnet as far as possible, thus the method for the close or identical as far as possible elimination EMS type magnetic-levitation train track coupling vibration of the gap data of the position with joint efforts of electromagnetic force that produces of the gap data making it gather and levitating electromagnet.
Design plan: EMS type magnetic suspension train vehicle be by the track manufactured by levitating electromagnet and ferromagnetic material between electromagnetic attraction suspend in orbit.Stable in order to what ensure to suspend, need suspension control system to coordinate with it, correspondingly need assemblage gap sensor to obtain gap signal between levitating electromagnet and track as control variable for suspension control system.The application is on structure design for this reason: eliminate because gap sensor is installed on one end of levitating electromagnet thus this major reason of initiation magnetic-levitation train track coupling vibration, be exactly position and the quantity of reasonable Arrangement gap sensor, the Resultant force of the electromagnetic force that its synthesising position is produced close to levitating electromagnet as far as possible, thus gap data between the track making it gather and gap sensor is identical as far as possible with the gap data at the Resultant force place of the electromagnetic force that levitating electromagnet produces.That is:
The position of reasonable Arrangement gap sensor and quantity: adopt " gap sensor is arranged on the centre of levitating electromagnet " organization plan and " levitating electromagnet is divided into two parts and two parts levitating electromagnet links together on electrically; gap sensor is arranged on the centre of two parts levitating electromagnet " organization plan, gap sensor only needs installation one group.
The Resultant force of the electromagnetic force that its synthesising position is produced close to levitating electromagnet as far as possible: gap sensor install a position in theory one just passable, but in order to reliable operation and leap track discontinuities in engineering, usually a position, three gap sensors are installed, three gap sensors are arranged at a certain distance on direction of travel, and the principle taking three to get two selects rational data as the gap data gathered.Synthesising position just refers to the line mid point of the position of two gap sensors being used data.
The Resultant force of the electromagnetic force that the position of synthesis is produced close to suspension magnet is as much as possible core of the present invention.Prior art due to the synthesising position of gap sensor and the Resultant force deviation of levitating electromagnet electromagnetic force very large, the displacement data of the track girder that gap sensor collects and the track girder actual displacement produced under electromagnetic force is inconsistent, causes control system carry out suspend control according to off-square displacement data and cause vibration.The profile of levitating electromagnet and line track is constant at length direction, and the Resultant force being distributed in the electromagnetic attraction in electromagnet length that therefore levitating electromagnet produces is just at the middle part of levitating electromagnet.
The gap data at the Resultant force place of the electromagnetic force that the gap data between track and gap sensor should produce with the levitating electromagnet mentioned below is identical, can ensure the stable of suspend control.
The gap data at the Resultant force place of the electromagnetic force that levitating electromagnet produces refers to the gap data between Resultant force place levitating electromagnet and track.
Technical scheme: a kind of method eliminating EMS type magnetic-levitation train track coupling vibration, comprise EMS type magnetic suspension train vehicle levitating electromagnet and multiple gap sensor, the center line average values present position of the position of multiple gap sensor is close or identical with the position of making a concerted effort of the electromagnetic force that levitating electromagnet produces.
The present invention is compared with background technology, and one is under the condition substantially not increasing cost, eliminates the important principle origin cause of formation of magnetic-levitation train track coupling vibration; Two is the possibilities occurred owing to decreasing vibration, thus reduces design and the debugging difficulty of vehicle suspension system (comprising suspension control system); Three is the possibilities occurred owing to decreasing vibration, thus the suspension property of vehicle can improve further; Four be prior art in order to reduce vibrative possibility, require that line track beam has very high rigidity (deflection span ratio reaches more than 1/3800), far above the rigidity (1/800) required by general wheel-track type track traffic; After adopting the present invention, the rigidity of track girder can be reduced to about 1/1000, thus significantly reduces line project construction cost.
