Before need to by research technique come to Bus Frame carry out life-cycle verifying, avoid Bus Frame problem from flowing to market, make to user
With making troubles, or even cause traffic accident, causes personnel and property loss.
Bus Frame is commented to realize currently, mainly carrying out life-cycle test on the proving road at test site by vehicle
Estimate verifying, vehicle needs travel thousands of or even up to ten thousand kilometers of progress road loop tests on proving road, this verification mode at
This height, period are long.
Summary of the invention
The purpose of the present invention is to provide a kind of methods of vehicle frame fast verification, to solve in the prior art to vehicle
Problem at high cost when skeleton is verified, the period is long.
To solve the above problems, the method for the vehicle frame fast verification in the present invention adopts the following technical scheme that: trying
Pit and/or protrusion for simulating the impact operating condition on true road surface is set on lane, passes through the stress of test impact operating condition
Peak value realizes the fast verification to vehicle frame.
The depth of the pit is adjustable, and the height of the protrusion is adjustable.
Foundation pit is set on proving road, support frame is installed in foundation pit, releasable connection has pit module and/or convex on support frame
Platform module, by replacement pit module and boss module realize respectively pit depth can reconcile protrusion height it is adjustable.
The pit module and boss module are connect with the same support frame.
Support frame as described above passes through the connection structure being arranged at the top of it and pit module and/or the removable fixation of boss module even
It connects, support frame as described above includes the accommodating chamber for accommodating the recessed portion of pit module, and accommodating chamber is for accommodating the recessed of different depth
Cheat module.
The pit module is overlapped by the opening opening's edge of the accommodating chamber of overlap joint flanging and support frame and is supported, the recessed portion
It is arranged in the middle part of pit module, the bottom surface of recessed portion is plane, overlaps and is equipped with slope transitions between flanging and recessed portion.
The submodule that two or more is set side by side is spliced into pit module.
The boss module includes bottom plate, and the one side of bottom plate is plane for simulating flat road surface, is set on another side
There is raised line for simulating protrusion.
Floor is set along the length direction interval of raised line between raised line and bottom plate.
The support base on foundation pit is used to support in the lower section setting of the recessed portion of pit module.
The beneficial effects of the present invention are: the pit for simulating the impact operating condition on true road surface is arranged on proving road
And/or protrusion, the fast verification to vehicle frame is realized by the peak stress of test impact operating condition.Need to vehicle frame into
When row validation test, pit or protrusion realize the simulation of severe impact operating condition of the vehicle on true road surface, make verifying knot
Fruit is closer to the truth, while the impact operating condition severe to vehicle frame progress is equivalent to improve and test vehicle frame
Intensity is demonstrate,proved, life-cycle proving period is shortened, when vehicle frame has local defect, no longer needs to carry out life-cycle verifying survey
Examination need to only pass through the verifying of pit and protrusion to the severe impact operating condition of local defect progress of vehicle frame on proving road
Achieve the effect that the life-cycle is verified, save the cost shortens proving period.
