Abstract
The invention relates to a calibration testing method for a traverse stabilizer bar of a sedan. The method is characterized by specifically comprising the following steps of: A, propping the whole sedan by using a lifter and a support arm; B, disassembling two ends of connecting the stabilizer bar and an auxiliary frame from the whole sedan, wherein a connection assembly of the middle part of the stabilizer bar and the sedan body plays a role of a special fixture, namely the stabilizer bar is allowed to rotate around the axis thereof; C, supporting the disassembled end of the stabilizer bar, namely a fixed end by a square box, and loading and calibrating at the other end, namely a loading end by using hung weights; and D, after a testing result is obtained, fastening the two ends of the stabilizer bar and the auxiliary frame again. The disassembly and assembly time and cost, and manpower and material resources are saved, and the magnitude and direction of loading are correct so as to achieve the high calibration testing accuracy.
Description
Technical field:
The present invention relates to a kind of car QS rating test method, belong to a kind of test, field tests.
Background technology:
The forward and backward QS of car is one of car vitals.Operating load---moment of torsion when measuring its actual uses at first will be determined relation between suffered moment of torsion of stabilizer bar and the torsional deflection (strain) by rating test.Present caliberating device is shown in Fig. 1-2, and its detailed process is: at first pull down stabilizer bar 2 fully by the lifting machine from car load; Reach corresponding processing matable assembly by stabilizer bar and vehicle body connecting assembly and form special jig 1, with special jig 1 stabilizer bar 2 is fixed on the square chest 6, the stiff end of stabilizer bar connects the fixed bar 5 of processing, and fixed bar 5 and square chest 6 all fix on the ground; Auxiliary with overhead traveling crane, taked the hanging method to load.The stabilizer bar loading end is connected to the overhead traveling crane suspension hook through leading screw, pulling force sensor, wire rope.By the size of rotational lead screw adjusting to upper pulling force, this power will guarantee vertical ground.Stabilizer bar stiff end (other end) is fixed through the fixed bar vertical ground, with the loading end acting in conjunction, by rotating threaded shaft, applies the steady torque (torque that it is rotated around axis) of different value for stabilizer bar 2.Obtain after the test findings stabilizer bar being reinstalled on the car.There is following shortcoming in this method:
1. dismounting difficulty.Integral body is pulled down stabilizer bar to waste time and energy, and some vehicle must be pulled down as other assemblies such as steering box, engine mountings earlier just can pull down stabilizer bar, and disassembly process extremely bothers.
2. timing signal also must have craneman's operation crown block to cooperate many labor intensive and equipment except that needs are made special jig.
3. to guarantee the loading direction vertical ground, need a plurality of angles of conversion to estimate, adjust the overhead traveling crane position, guarantee the precision difficulty.
4. loading size is to realize by rotating threaded shaft.After load (pulling force) was adjusted to a certain value, because of the flexible distortion of wire rope that suspension hook is connected with stabilizer bar, load can reduce gradually, was difficult to keep stable.Load reduces when particularly being added to big load amplitude and speed obviously become big, and test repeatability is relatively poor, stated accuracy is lower.
Summary of the invention:
The object of the present invention is to provide a kind of car QS rating test method, do not need from car load, to pull down fully stabilizer bar, only take the two ends that stabilizer bar is connected with subframe apart, simultaneously by change load mode with save time, expense and improve the rating test precision.
Technical scheme of the present invention is achieved in that car QS rating test method, and it is characterized in that: concrete grammar may further comprise the steps: A, utilize lifting machine and trailing arm to hold up car load;
B, from car load, take the two ends that stabilizer bar is connected with subframe apart, utilize the stabilizer bar middle part and the connecting assembly of vehicle body to play the effect of special jig; Promptly only allow stabilizer bar to rotate around its axis;
C, an end of taking apart with square chest supporting ﹠ stablizing bar are stiff end, and loading end is that the other end loads demarcation with hanging counterweight from above;
D, obtain the two ends that fastening again stabilizer bar is connected with subframe after the test findings.
Good effect of the present invention is not need to pull down fully from car load stabilizer bar, saves time, the expense of dismounting; And hang formula from above and load by changing into, utilize that the gravity direction of object own points to the earth's core (vertical ground), the constant characteristic of size when static, not only save human and material resources, can guarantee again to load size and Orientation accurately to obtain higher rating test precision.

Embodiment 1: Jetta car stabilizer bar rating test
Test objective: demarcate Jetta suffered moment of torsion of car stabilizer bar and strain relation, prepare under the car load transport condition, carrying out the test of stabilizer bar torque load.
Testing equipment: lifting machine, square chest bracing or strutting arrangement, counterweight and steelyard hook
● DEWETRON 501A SYSTEM hyperchannel number is adopted equipment, and sequence number is: 15060023
● BHF350-2HA (11) type resistance strain gage, sensitivity coefficient is 2.08.
Test findings:
Adopt method as shown in Figure 3-4 to test, A, utilize lifting machine and trailing arm 5 to hold up car loads 4;
B, from car load, take the two ends that stabilizer bar is connected with subframe apart, utilize the stabilizer bar middle part and the connecting assembly 1 of vehicle body to play the effect of special jig; Promptly only allow stabilizer bar to rotate around its axis;
C, an end of taking apart with square chest 6 supporting ﹠ stablizing bars 2 are stiff end, and loading end is the other end demarcation that loads of hanging counterweight 3 from above;
D, obtain the two ends that fastening again stabilizer bar is connected with subframe after the test findings.
In order to last method stabilizer bar 2 is carried out twice and load gradually and uninstall process test gradually, relation curve as shown in Figure 5 between Jetta car stabilizer bar torsional strain " x " that data processing obtains and the suffered moment of torsion " y "; As seen corresponding a plurality of data points, test repeated fine.The related coefficient square value R of " x " and " y "
2Be 0.966,, illustrate that stated accuracy is higher very near 1.
