Description
Technical field
The present invention relates to a kind of mechanics of materials detection range, particularly a kind of pressure experimental device of material.
Background technology
EMUs equipment compartment skirtboard is the vitals of motor-car equipment compartment, for hanging device under the car provides lateral protection.Skirtboard is provided with ventilating opening, and ventilating opening is installed air grid.The effect of air grid is a rain and snow, dustproof and discharge water etc.The pressure design index of skirtboard ventilating opening grid need satisfy car body aerodynamics load, and experimental study shows that the aerodynamics load of existing domestic EMUs equipment compartment skirtboard ventilating opening grid is about 6KPa.If do not detect before the product export, then will directly influence the reliability of product in actual engineering is used through this technical indicator.Therefore, a kind of EMUs equipment compartment skirtboard ventilating opening grid pressure test method need be provided, the bearing capacity of EMUs equipment compartment skirtboard is measured accurately, to guarantee that product quality is qualified.Still there are not standard test method and device at present both at home and abroad about EMUs equipment compartment skirtboard ventilating opening grid pressure detection.
To this technological gap, be badly in need of a kind of EMUs equipment compartment skirtboard ventilating opening grid pressure test method and device are provided, make it carry out product pressure and detect EMUs equipment compartment skirtboard ventilating opening grid, guarantee product quality.
The utility model content
In view of this; The purpose of the utility model provides a kind of EMUs equipment compartment skirtboard ventilating opening grid pressure experimental device; Utilize the detection test before this device can dispatch from the factory to EMUs equipment compartment skirtboard ventilating opening grid; Guarantee that the ventilating opening grid can satisfy the required mechanical property of actual condition, and then guarantee the stable operation and the safety of EMUs.
The purpose of the utility model realizes through following technical scheme: a kind of EMUs equipment compartment skirtboard ventilating opening grid pressure experimental device; Comprise testing table, be placed horizontally at the skirtboard test specimen on the testing table and vertically be arranged on the skirtboard ventilating opening grid and add sandbox; The said two symmetrical bases that add sandbox are the arc that adapts with the skirtboard ventilating opening; Also comprise clock gauge, the probe of said clock gauge is arranged on the ventilating opening grid.
Further, the probe setting of said clock gauge and ventilating opening grid center;
Further, the said sandbox bottom that adds also is symmetrical set the through hole of being with valve.
The beneficial effect of the utility model: the test unit of the utility model, not only can carry out product pressure to EMUs equipment compartment skirtboard ventilating opening grid and detect, guarantee product quality; And then stability and the security of driving have been guaranteed; Also detect test unit for industry provides a kind of product of standard simultaneously, remedied the technological gap of this technical field, equipment and method of operating are simple; The test findings accuracy rate is high, suitable applying.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model.
Embodiment
Fig. 1 is the structural representation of the utility model.As shown in the figure; The EMUs equipment compartment skirtboard ventilating opening grid pressure experimental device of present embodiment; Comprise testing table 1, be placed horizontally at the skirtboard test specimen 2 on the testing table and vertically be arranged on the skirtboard ventilating opening grid and add sandbox 3; The said two symmetrical bases that add sandbox are the arc that adapts with the skirtboard ventilating opening, also comprise clock gauge (not drawing among the figure), and the probe of said clock gauge is arranged on the ventilating opening grid.
The method of application of this EMUs equipment compartment skirtboard ventilating opening grid pressure experimental device is:
A, equivalence are uniformly distributed with crooked the loading: (or inboard) loads the ventilating opening grid from the skirtboard outside to adopt the equivalence of river sand quality to be uniformly distributed with crooked loading method, makes the even stress deformation of ventilating opening grid; According to actual needs toward adding the river sand of loading certain mass in the sandbox;
B, load deflection measurement amount: utilize clock gauge to measure on the ventilating opening grid certain any displacement deformation amount a, and record;
C, equivalence are uniformly distributed with crooked unloading: remove the river sand quality gradually, the ventilating opening grid is evenly unloaded;
D, answer deflection are measured: utilize clock gauge to measure the answer displacement b of measured point, unloading back, and record;
E, obtain the practical distortion amount c of measured point: utilize load deflection amount a to deduct and reply the practical distortion amount c that deflection b can obtain the measured point, i.e. c=a-b;
F, data contrast: practical distortion amount c and standard value are compared, if practical distortion amount c overgauge value then is a substandard product; If practical distortion amount c is less than or equal to standard value, then be specification product.
The test unit of the utility model not only can carry out product pressure to EMUs equipment compartment skirtboard ventilating opening grid and detect, and guarantees product quality; And then stability and the security of driving have been guaranteed; Also detect test unit for industry provides a kind of product of standard simultaneously, remedied the technological gap of this technical field, equipment and method of operating are simple; The test findings accuracy rate is high, suitable applying.
As further improvement to the foregoing description, the probe setting of said clock gauge and ventilating opening grid center.In the process of the test, grid center deflection is maximum, and therefore selecting the grid center is that check point is more representative, and test findings is more accurate.
As the further improvement to the foregoing description, the said sandbox bottom that adds also is symmetrical set the through hole of being with valve.In unloading river sand process, can pass through by-pass valve control, guarantee the homogeneity and the continuity that unload, convenient and swift, help the accuracy of test structure.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the utility model is specified with reference to preferred embodiment; But those of ordinary skill in the art makes amendment to the technical scheme of the utility model or is equal to replacement, and does not break away from the aim and the scope of the utility model technical scheme, and it all should be encompassed in the middle of the claim scope of the utility model.
