Description
Technical field
This utility model is related to a kind of train impact-model testing equipment.
Background technology
In recent years, with the raising of train running speed, the event that the whole world occurs train derailing happens occasionally, such as 1998
The ICE train derailment accident occurred near German Ai Shede towns, the train of Korea YTN high-speed railways generation in 2011 takes off
The rear end collision of motor train derailment accident that rail accident, the same year China Wenzhou occur, and occur near Spain Santiago in 2013
Bullet train derailment accident etc..These train derailment accidents not only cause mass casualties, but also may be to railway
Infrastructure cause significant damage, especially when derailment accident occurs in shield tunnel under water of growing up, clash into shield tunnel
Caused tunnel destruction easily induces the secondary disasters such as floods, increases rescue difficulty and casualties rate, and serious will cause tunnel
Road floods and scraps.
However, to study dynamic response and vandalism that shield tunnel is clashed in train derailing, it is necessary to obtain train and take off
Rail impact load.At present, not yet there is the train derailing impact load curve of actual measurement, only research is all by Nonlinear Finite
Meta software is modeled to train marshalling list, then clashes into the different train marshalling lists of rigid wall acquisition, different stroke speeds and difference and hits
Hit the train impact load time-history curves of angle.It is complicated, simple that this numerical simulation mode is related to high speed contact problem, numerical modeling
Change and assume more, workload of operation is big；In addition affect the objective factor that train clashes into sufficiently complex, the train that theoretical simulation is obtained
Derailing impact load curve is big with the deviation of actual impact load, reliability is low.
Utility model content
The purpose of this utility model is to provide a kind of train impact-model testing equipment, the device can simulate train marshalling list with
The shock of friction speed, different projected angle of impacts to tunnel side wall, obtains the impulsive force that tunnel is clashed in train derailing, is the anti-of tunnel
Hit to design and provide more accurate, reliable test basis with building, and then avoid train derailing shock from doing great damage tunnel,
The secondary disasters such as induction floods, to reduce injures and deaths and the loss of accident generation.
It is to it is characterized in that this utility model solves the technical scheme that its technical problem adopted：
The middle part of table top disposes the i shaped steel of analog orbit, train marshalling list model to be installed on i shaped steel；Train is compiled
The front part sides of group model are provided with wing plate, and on the table top in wing plate dead astern blow cylinder is fixed with；Blow cylinder and air pressure
Contracting machine is connected；
The rigid baffle of the adjustable angle of simulation tunnel abutment wall is fixed with table top in front of described train marshalling list model,
Rigid baffle middle part is provided with two to force transducer；
The table top of described i shaped steel front portion side installs two generating lasers, the platform of i shaped steel front portion opposite side
Face correspondence installs two laser inductors.
Using method of the present utility model and principle are：
Rigid baffle is adjusted and is locked to set angle；Subsequent start-up air compressor, treats that air compressor air pressure reaches
During to the air pressure for setting, restart blow cylinder.The impulse member of blow cylinder i.e. the two of high-speed impact train marshalling list model forward
Side wing, makes train marshalling list model advance along i shaped steel rail high speed, and clashes into rigid baffle.Meanwhile, before i shaped steel
The generating laser and laser inductor in portion, measures the speed for clashing into moment train marshalling list model, the power sensing on rigid baffle
Device measures the impulsive contact force of the train marshalling list model for clashing into moment.
The air pressure of adjustment rigid baffle angle and air compressor, you can measure：Different projected angle of impacts, the different speeds of service
Impact force between Train and tunnel.
Compared with prior art, the beneficial effects of the utility model are：
This utility model drives train marshalling list by the rigid baffle simulation tunnel abutment wall of adjustable angle, by blow cylinder
Model advances at utmost speed, and realizes the analog simulation test of train high-speed impact tunnel.Simultaneously by generating laser and laser induced
Device accurately measures speed of service when train marshalling list model clashes into, and measures shock moment by the force transducer on rigid baffle
Train marshalling list model impulsive contact force.Tunnel is clashed into so as to obtain different angles, the derailing of friction speed Train by simulation test
The experimental data of the impulsive force in road.The experimental data that it is obtained is more accurate than theoretical simulation data, reliable, is the anti-of tunnel
Hit to design and provide more accurate, reliable test basis with building, and then avoid train derailing shock from doing great damage tunnel,
The secondary disasters such as induction floods, to reduce injures and deaths and the loss of accident generation.
Above-mentioned train marshalling list model is made up of 6 section auto models, is connected with spring between auto model.
Because the impact force time-history curves of train marshalling list are mainly relevant with front 5-6 section vehicles, the knockout process time is extremely short, row
When the later vehicle inertia power of section of car marshalling 7 is delivered to impact site by the spring between vehicle after knockout process
Section, it is difficult to form synergistic effect.Therefore, the train marshalling list model being made up of 6 section auto model spring connections, can meet mould
Intend the requirement that train in practice clashes into the impact force for producing；Simultaneously the vehicle joint number of train marshalling list is less, the requirement to power is low,
The structure of testing equipment simplifies, and experimentation cost is low.
The concrete structure that above-mentioned train marshalling list model is installed on i shaped steel is：The two bottom sides of auto model are solid
Surely the bottom for having the L-type postive stop baffle of infolding, auto model is connected with Roll, the transverse slat upper surface of L-type postive stop baffle
It is connected with lower Roll, the riser medial surface connection anticollision bearing of L-type postive stop baffle；I shaped steel top board is embedded in universal rolling
Between ball, lower Roll and anticollision bearing.
This structure, it is ensured that train marshalling list model high-speed motion on i shaped steel, is greatly reduced and I-shaped
The frictional force of shaped steel, more conforms to the movement relation of train in reality and track, further ensure test data it is truer,
It is reliable.
The concrete structure of above-mentioned rigid baffle is：Vertical rotating shaft on table top is inserted in the axocoel of vertical steel plate, steel
Backboard is welded with triangle ribbed stiffener from the back side both sides of train marshalling list model, and the screw rod of clamping screw passes through triangle ribbed stiffener
Base groove and table top on arc-shaped slot pass connection locking nut；The center of circle of described arc-shaped slot pass is vertical rotating shaft
Axle center.
So, rigid baffle can be fixed by vertical rotating shaft arbitrarily rotation and by clamping screw, such that it is able to convenient
Regulation set arbitrary projected angle of impact, the angle unpredictability for clashing into tunnel inner wall with train derailing in reality is consistent；
The purpose for selecting rigid baffle be the impact load that utilize it rigidly to ensure that test obtains not because of the different of baffle plate material not
Together；Back side both sides welding triangle ribbed stiffener of the steel plate away from train marshalling list model, it is ensured that the intensity of rigid baffle, protects it
Do not broken and shifted by train marshalling list model.
