A kind of test method of above-mentioned detection stabilizer bar weld strength test-bed, the described method includes following steps Suddenly:
The first step:Suitable lateral stability pipe is selected, is installed on test-bed;Second step:Measure rectangular tube dead weight production Raw torque;3rd step:Institute's measured data demarcates pull pressure sensor, each display is shown when making not apply external force Numerical value for rectangular tube because dead weight generate torque value half;4th step:Make rectangular tube with dead weight FREE TORSION, and check aobvious Show whether device show value is calibration value;5th step:Stubborn panel nut by hand makes two display numerical value synchronous;6th step:Work as display It when device numerical value reaches specific torsion, stops operation, checks whether lateral stability pipe weld seam cracks, if cracking, returns to the first step, if It does not crack, then carries out the 8th step;7th step:Specific torsion is maintained, stands 30min, if cracking, returns to the first step, if not cracking, Then carry out the 9th step;8th step:Continue to increase torque, and whether Real Time Observation has crack generation, record generates torsion during crack Square value;9th step:Panel nut is unclamped to initial position, off-test.
Compared with prior art, the advantage of the invention is that:
1st, cost is relatively low, and operates very simple.
2nd, torsion-testing scope is larger, and test section is [800,8000] Nm, fully meets testing requirement.
3rd, accuracy of detection is higher, is 1%, fully meets engineering test demand.

Specific embodiment
The present invention is described in further detail below in conjunction with attached drawing embodiment.
As shown in Fig. 1-Fig. 4, a kind of detection stabilizer bar weld strength test-bed in the present embodiment, including firm Property pedestal 1, column assembly 2 is provided in the one side of the rigid base 1, by specific frock, by one end of stabilizer bar 3 It is removable lining to be fixed on column assembly 2, while the other end is removable lining is fixed on the higher rectangular tube 4 of rigidity, the side Shape pipe 4 is mutually perpendicular to stabilizer bar 3 in same level, annular groove is opened in 4 end of rectangular tube, in annular groove Interior interspersed rectangle stud 5 is simultaneously fixed on rigid base 1, while two oscillating bearings 6 are symmetrically installed above 4 end of rectangular tube, Pull pressure sensor 7 is provided on described two oscillating bearings 6, is installed in the middle part of the rectangular tube and pressure The connected display 8 of sensor 7, is provided with pressing plate 9, the both ends of the pressing plate 9 are interspersed with guiding above the rectangle stud 5 Column 10, the bottom of the lead 10 are fixed on rigid base 1, and the other end of the pull pressure sensor 7 is with passing through rectangle The pressing plate 9 of stud 5 is threadedly coupled, and applies torque to stabilizer bar 3 by tightening panel nut 11, torque can be by showing Show that device is shown, the stabilizer bar 3 is stable in by buckling preventing support bar 12 between column assembly 2 and rectangular tube 4.
The present embodiment provides a kind of test method of above-mentioned detection stabilizer bar weld strength test-bed, the methods Comprise the following steps:
The first step:Selection uses the lateral stability pipe of certain welding procedure, and mode is installed as shown in Figure 2.Second step:It is square Pipe dead weight can generate the torque for making lateral stability rod twisting, thus need to measure the torque that rectangular tube dead weight generates, the operation first It can be realized in large commercial CAD software.3rd step:Institute's measured data demarcates pull pressure sensor, makes not apply outer The numerical value that each display is shown during power is rectangular tube because of the half of the torque value of dead weight generation.4th step:Make rectangular tube with certainly Weight FREE TORSION, and check whether display show value is calibration value.5th step:Stubborn panel nut by hand, observes display number Word changes.6th step:If two displays show numerical value, difference is larger, changes the mode for twisting panel nut, makes two display numerical value It is synchronous.7th step:It when display numerical value reaches specific torsion, stops operation, checks whether lateral stability pipe weld seam cracks.If Cracking returns to the first step.If not cracking, the 8th step is carried out.8th step:Specific torsion is maintained, stands 30min, if cracking, is returned The first step is returned, if not cracking, carries out the 9th step.9th step:Continue to increase torque, and whether Real Time Observation has crack generation, Record generates torque value during crack.Tenth step:Panel nut is unclamped to initial position, off-test.
In addition to the implementation, it is all to use equivalent transformation or equivalent replacement present invention additionally comprises there is an other embodiment The technical solution that mode is formed should all be fallen within the scope of the hereto appended claims.
