Unidirectional force snesor is mounted on load bar, can not accomplish to be loaded on same three-dimensional force transducer, carries out road mould
Intend experiment.
The content of the invention
The technical problem to be solved by the utility model is to provide a kind of three axis coupling Road Simulation Test frock, the frocks
Using the combination of cross torsion elements ball adding hinge spindle, keep within bounds the rotation in tri- directions of X/Y/Z, can preferably reappear and be suspended at
Stress on real vehicle real road eliminates rotating torque, in order to which stress of the tests exemplar in tri- directions of X/Y/Z is perfect
Decoupling, three direction force after decoupling will not influence each other, and substantially increase the precision of suspension road analogy iteration.
The utility model is realized in this way：A kind of three axis coupling Road Simulation Test frock, including pedestal, sample to be tested
Part and three-dimensional force transducer, the exemplar to be tested are arranged on pedestal, and the output terminal of the three-dimensional force transducer passes through sensing
Device mounting bracket is connected with exemplar to be tested, and three axis force loading stent is provided on the input terminal of the three-dimensional force transducer；Institute
State three axis force loading stent have in same level and orthogonal X to connecting shaft and Y-direction connecting shaft and perpendicular to
The Z-direction connecting shaft of horizontal plane；The X is connected by cross torsion elements to connecting shaft with X to loading axis, the Y-direction connecting shaft
It is connected by cross torsion elements with Y-direction loading axis.
The cross torsion elements are in series by two pieces of orthogonal spring steel plates.
The Z-direction connecting shaft is provided at both ends with spherical hinge.
Three axis of the utility model coupling Road Simulation Test frock uses the combination of cross torsion elements ball adding hinge spindle,
Keep within bounds the rotation in tri- directions of X/Y/Z, while using the resilience performance of torsion elements, the deformation stroke in three directions of guarantee can be more
Good reproduction is suspended at the stress on real vehicle real road, forms of motion and athletic posture and real vehicle state is basically identical,
And the data of sensor feedback can be made to eliminate rotating torque, in order to the perfect solution of stress of the tests exemplar in tri- directions of X/Y/Z
Coupling, three direction force after decoupling will not influence each other, and substantially increase the precision of suspension road analogy iteration, be product development
Verification provides true, reliable result of the test.
