Description
Technical field
The utility model relates to a kind of be used to the measure relative displacement at flexible steel in flat section tubing two ends and the proving installation of corner, belongs to the proving installation that a kind of flexible steel in flat section tubing complex parameters is measured.
Background technology
At present; The relative displacement and the corner of flexible steel in flat section tubing such as real vehicle kinetic measurement gas outlet telescopic joint and charge air cooler turnover tracheae; The domestic basic good way that do not have; Can only be in the axial deformation of measuring on the stand under the maximum load situation, however the 3 D deformation under real vehicle actual temperature and the operating mode is the biggest factor that influences the flexible steel in flat section tubing permanance.Therefore to measure the data of three-dimensional six degree of freedom be to obtain the only resource of True Data to real vehicle.
Summary of the invention
The purpose of the utility model provides a kind of be used to the measure relative displacement at flexible steel in flat section tubing two ends and the proving installation of corner; Can be according to set angle installation position displacement sensor; The displacement of six angles of measurement space, thus calculate X, Y, Z three direction displacement and Rx, Ry, the Rz three-dimensional flexion torsion of flexible steel in flat section tubing.
The technical scheme of the utility model is achieved in that and is used to measure the relative displacement at flexible steel in flat section tubing two ends and the proving installation of corner; Form by sensor stand, guiding trestle, fixed support, displacement transducer, sensor backguy, centering set bolt; It is characterized in that: three sensor stands are 120 ° and are distributed on the tested pipeline; Six two of displacement transducers are one group and are fixedly connected on three sensor stands, and displacement transducer connects the sensor backguy, and the sensor backguy is passed on the fixed support that guiding trestle is connected to the tested pipeline other end; The pilot hole of guiding trestle is parallel with sensor stand; Sensor backguy and fixed support are fixed, and are 60 ° of phase differential, and sensor stand, guiding trestle, fixed support all are fixed on the tested pipeline through the centering set bolt.
The good effect of the utility model is the displacement that can obtain the three-dimensional six degree of freedom of flexible pipe, also for bench test input and product design accurate data is provided.
