Match, the length that bracket 2 is stretched out from engineering machinery vehicle frame 1 is consistent with actual condition.
Embodiment 1: test when three outrigger support of simulation
Engineering machinery is in hoist operation process, it is possible that the state of three outrigger supports, i.e., one of vertical leg
Do not stress or be it is hanging, by surveying the support reaction of the other three vertical leg or the other three can be obtained by theoretical calculation at this time
The support reaction size of vertical leg.
When test, first by the content of present invention assembly subject engineering machinery vehicle frame 1 and bracket 2, hydraulic unit driver 5, power detection
Device 4 and correlation test tooling.The corresponding load being applied in vertical leg is simulated by hydraulic unit driver 5 on test-bed
Lotus, with parameters such as strain, displacements at 2 relevant position of testing engineering machinery vehicle frame 1 and bracket.
Embodiment 2: simulation test and fatigue test when simulation hoist object revolution
For engineering machinery in hoist operation process, the revolution of hoist object is a kind of common operating condition, the support reaction being reflected on supporting leg
Situation of change is that the support reaction on four supporting legs constantly changes with the difference of weight position.Actual measurement four can be passed through at this time
The support reaction of a vertical leg obtains the support reaction size variation situation of four vertical legs by theoretical calculation.
When test, first by the content of present invention assembly subject engineering machinery vehicle frame 1 and bracket 2, hydraulic unit driver 5, power detection
Device 4 and correlation test tooling.The corresponding dynamic being applied in vertical leg is simulated by hydraulic unit driver 5 on test-bed
Live load, engineering machinery vehicle frame 1 and 2 stress situation of change of bracket when simulation hoist object turns round.Circulating repetition loads the load
The fatigue life simulation test of engineering machinery vehicle frame 1 and bracket 2 may be implemented in curve.
The present apparatus effectively carries out engineering machinery by test-bed in the way of simulation vertical leg support reaction load
The quiet dynamic operation condition of vehicle frame and bracket, the test such as extreme operating condition and tired operating condition, test process control is strong, close to reality
Operating condition, test result can reflect the actual performance of frame body, convenient for parameters such as research and analysis stress, deformations.
