Technical scheme of the present invention is achieved in that vehicle bridge C word beam test device; Form by clapboard built-up jig, turnbarrel built-up jig, testing table; It is characterized in that: the clapboard built-up jig; Be made up of top board, bolt pillar, wedge-shaped floor, six bolt pillar lower ends are inserted in the adjustment bolt hole on the wedge-shaped floor, and bolt pillar upper end is fixedly connected with top board; The turnbarrel built-up jig is made up of sleeve assembly, sleeve roller support, base, web member, and sleeve assembly is that axle is movably connected on the sleeve roller support with the web member, and sleeve roller support bottom is fixedly connected with base; Clapboard built-up jig and turnbarrel built-up jig are fixed on the testing table.
The test method of described vehicle bridge C word beam realizes according to the following steps: the vehicle bridge C word beam casing that (1) will test is clipped on the clapboard built-up jig; Displacement through the adjustment of the bolt pillar on clapboard built-up jig vehicle bridge casing ground vertical direction makes vehicle bridge casing and spindle nose maintenance level; (2) axle tag partly inserts in the sleeve assembly of turnbarrel built-up jig, positions through the turnbarrel anchor clamps; (3) go up the design of application point force application location at C word beam supporting surface, supported underneath power serves as the below fulcrum with vehicle bridge casing and spindle nose, and last application point and below fulcrum form acting force and reacting force; (4) test frequency adopts 4.2hz, and total test force is set at 2.5 times of vehicle bridge rated loads, and one-sided beam calculates by 1/4 times that puts in order bridge load, and drafting the qualified life-span target of test specimen is 50,000 times.
Good effect of the present invention is the test of carrying out through the method, constantly finds the weak link in the product, for the product tackling key problem provides technical support.Through technological improvement, the bench test argument in a circle, the existing product testing life-span has reached 10.5 ten thousand times, and product reliability is greatly improved.
Description of drawings
Fig. 1 is a structure drawing of device of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further: as shown in Figure 1; Vehicle bridge C word beam test device; Form by clapboard built-up jig, turnbarrel built-up jig, testing table, it is characterized in that: the clapboard built-up jig, form by top board 1, bolt pillar 2, wedge-shaped floor 3; Six bolt pillar 2 lower ends are inserted in the adjustment bolt hole on the wedge-shaped floor, and bolt pillar 2 upper ends are fixedly connected with top board 1; The turnbarrel built-up jig is made up of sleeve assembly 4, sleeve roller support 5, base 6, web member 7, and sleeve assembly 4 serves as that axle is movably connected on the sleeve roller support 5 with web member 7, and sleeve roller support 5 bottoms are fixedly connected with base 6; Clapboard built-up jig and turnbarrel built-up jig are fixed on the testing table.
The vehicle bridge C word beam casing 9 that to test during test is clipped on the clapboard built-up jig, and the displacement through the adjustment of the bolt pillar on clapboard built-up jig vehicle bridge casing 9 ground vertical direction makes vehicle bridge casing 9 and spindle nose maintenance level;
Last application point force application location design is at C word beam supporting surface, and supported underneath power serves as the below fulcrum with vehicle bridge casing and spindle nose, and last application point and below fulcrum form acting force and reacting force;
Test frequency adopts 4.2hz, and total test force is set at 2.5 times of vehicle bridge rated loads, and one-sided beam calculates by 1/4 times that puts in order bridge load, and drafting the qualified life-span target of test specimen is 50,000 times.
Process of the test comprises:
