Description
Technical field:
The utility model belongs to rolling stock's technical field, particularly to vehicle bogie frame active control skill
Art.
Background technology:
Bogie electromechanics active control be an emerging technology, with the raising of domestic and international high-speed railway speed class, with
And the development of Electromechanical Control technology, the active or semi- active control technology application in high-speed railway field will be more and more general
Time.The horizontal hunting stability of wheel track vehicle is one of problem of concern in Car design and utilization, and wheel track vehicle wheel is to employing
Taper tread is beneficial to vehicle and passes through curve, but brings its straight line horizontal hunting when running, when the speed of service surpasses
When crossing critical speed, lateral direction of car hunting unstability leads to serious oscillation crosswise, impact riding comfort or even peace of derailing
Quan Xing.During Bogie Designs, lateral stability of cars is taken into account by compromise selection vehicle structure suspension parameter and curve leads to
Cross performance, actual vehicle critical speed is raising 10～20% on the basis of maximum operational speed.But, vehicle is outstanding during being on active service
Hang the reasons such as element fault inefficacy, tread wear, line condition variation, lead to lateral stability of cars to reduce.Domestic actual fortune
, often there is because stability deficiency leads to framework vibration acceleration exceeded the accident of parking of reporting to the police, shadow in the high speed motor car in row
Ring the normal safe operation of train.
Research it has been shown that by control framework oscillation crosswise indirectly improve bogie stability be one effective and feasible
Method, dynamo-electric active control can compensate for the malfunction and failure of bogie mechanical part thus ensureing that wheel track vehicle is laterally stable
Property.
Utility model content:
The purpose of this utility model is to provide a kind of bogie frame oscillation crosswise control device, and it can efficiently solve structure
The problem of the oscillation crosswise active control of frame, to improve the operation stability of bogie.
The purpose of this utility model is achieved through the following technical solutions: a kind of bogie frame oscillation crosswise controls
Device, including by framework and wheel to and the bogie that forms of hanging element, framework and car body and wheel between pass through two respectively
System hangs and single stage suspension connects, and additional oscillator is constituted by spring is in parallel with damping, and its free end is provided with mass, the other end and
Truck longitudinal sill consolidates, and mass is provided with sensor；It is provided with inertia actuator in the middle part of the forward and backward end carriage of framework；On additional oscillator

Described additional oscillator is horizontally set on the inner side of framework two side girder, left and right arranged in a crossed manner.
The scope of described time lag amount is 1～100ms.
The utility model can improve vehicle high-speed and run transversal dynamic performance, due to wheel tread taper and track
The reasons such as irregularity, during oscillation crosswise, especially high-speed cruising oscillation crosswise aggravation in bogie when running, or even unstability and shadow
Ring vehicle smoothness and security.The utility model solution is that additional oscillator is secured transverse on framework, works as structure
During frame oscillation crosswise, drive additional oscillator vibration, by detecting the vibrational state of additional oscillator, such as the displacement of relative framework, attached
Plus the speed of oscillator and acceleration etc., as the feedback states of active control, control the oscillation crosswise of framework, to improve bogie
Operation stability.The utility model applies crosswise joint by the inertia actuator being arranged in the middle part of the forward and backward end carriage of framework
Power, controls the oscillation crosswise of framework.Research shows, when directly by feeding back framework transverse state come real-time control framework transverse-vibration
When dynamic, because the time lag in control system is inevitable, some time lags can make control system unstable, and leads to bogie to move
Mechanical property deteriorates.The additional oscillator of Parameter adjustable is transversely mounted architecturally by the utility model, meeting during framework oscillation crosswise
Drive this additional oscillator vibration, using the vibrational state of additional oscillator as feedback states amount.Direct feedback framework can be eliminated shake
Dynamic state leads to control unstable shortcoming because of system time lags, and by adjusting additional oscillator parameter, after optimizing feedback control
Bogie dynamic performance；In addition additional oscillator and the relative position of framework, with respect to framework lateral displacement, have state-detection
The convenient, advantage of high precision.
Advantage compared with prior art and good effect:
(1) by additional oscillator and framework with respect to framework lateral displacement, there is state-detection convenient, high precision excellent
Point；
(2) direct feedback framework vibrational state can be eliminated and lead to control unstable shortcoming because of system time lags；
