The coupling of the unfavorable factors such as labor and mutation effect will inevitably lead to the damage accumulation and degradation resistance of structure, thus
So that it is resisted natural calamity, the decline of the ability of even normal load, causes catastrophic emergency event under extreme case.
Rapid evaluation detection is carried out to service bridge structure health status, can effectively prevent outburst disaster and time control
The development of defect processed reduces loss, avoids casualties, it is ensured that the safety of structure and user.Wherein common total evaluation
The selection of technical basis driving source (input signal) can be divided into based on environment arbitrary excitation and be motivated based on move vehicle.Closely
The quick damage diagnosis method of bridge that controllable move vehicle load (Vehicle-Bridge Coupling System vibration) is based on over year is increasingly becoming research
Hot spot, by the dynamic response data of bridge structure or move vehicle under record analysis move vehicle load to service bridge structure
Health status carries out rapid evaluation.Related scholar has carried out a series of theoretical, numerical value and experimental study for this direction.Its
Middle model investigation is science of bridge building teacher and bridge scientific worker so as to determining and exploring bridge complex structural stress state
With response one of the important means of, and at present the field experimental study it is relatively fewer.As driving source and signal receiving device
Move vehicle model be the key components of test system, thus need to design one kind and can be widely used in difference
The modularization move vehicle model of vehicle-bridge coupling test demand.
Summary of the invention
To solve the above-mentioned problems, the invention proposes a kind of mobile load vehicle moulds of modularization for bridge model test
Type, it can be achieved that different load-carrying, vehicle frame wheelbase, wheel material, spring and damperparameters bridge model test traveling load add
It carries and requires, have many advantages, such as that at low cost, convenient and efficient, applicability is wide, the present apparatus can be used as static load suitable for different types of rridges
Static Model-Test can also be achieved different types of rridges power performance and damnification recognition method research examination under the traveling load of different parameters
It tests, the expanded research that can be widely used for bridge model test field.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of modularization for bridge model test is moved
Dynamic load vehicle model, including load vehicle vehicle body, load vehicle carriage, wheel, loading blocks, spring and damper, the load vehicle vehicle
Body is connect by spring and damper with load vehicle carriage, and load vehicle carriage lower part is equipped with wheel, and loading blocks are placed in load
On vehicle vehicle body；The total weight of mobile load vehicle model is adjusted by adjusting the quantity of loading blocks；
The load vehicle carriage is connected with the pedestal for fixing the spring and damper by fastening screw；It is described to add
The both ends of carrier vehicle vehicle frame are welded with traction link.
Further, the wheel is aerated rubber tyre, solid tire or plastics tyre.
Further, load vehicle carriage includes I-shaped upper frame and "-" type chassis, and the I-shaped upper frame front is with after
Portion is respectively arranged below with a "-" type chassis.
Further, the left and right sides of the "-" type chassis is symmetrical respectively is provided with one group of spring (5) and damping
Device (6).
The invention has the following advantages:
1, the present invention can be used as static load suitable for different types of rridges Static Model-Test, can also be achieved the shifting of different parameters
Different types of rridges power performance and damnification recognition method development test under dynamic load；
2, the present invention is according to the demand of test arrangement spring and damper, compared to traditional moving mass loading method closer to very
Real bridge move vehicle load condition, and spring and damperparameters are it is known that convenient for test quantitative analysis；
3, apparatus of the present invention use modularized design, and the modules such as vehicle frame, wheel, spring and damper can be changed quickly, can
Realize that the bridge model test traveling load load of different load-carryings, vehicle frame wheelbase, wheel material, spring and damperparameters is wanted
It asks.
