Embodiment
As shown in Figure 1, the present embodiment is mainly divided into control treatment system and performs feedback mechanism two parts.Control treatment system comprises computing machine and MCU; Perform feedback mechanism and comprise image capture module, moment load-on module and workbench.Computing machine is connected with image capture module, controls it and gathers image and obtain the image gathered.Simultaneous computer by MCU control moment load-on module, and obtains the data of real-time moment output by MCU.
As shown in Figures 2 to 6, workbench framework is built by aluminium section bar 12, and installs dividing plate 4 thereon, forms workplace.Sectional fixture 2 on dividing plate 4, in order to fixing steering wheel 3 to be measured.Mounting industrial camera 1 directly over steering wheel 3 to be measured, in order to carry out image acquisition to steering wheel 3 to be measured.Below dividing plate 4, line slide rail 11 is fixed on aluminium section bar 12, and linear slider 9 is arranged in line slide rail 11, and pressure transducer 6 is fixed in linear slider 9, and is connected with reducing motor 7 with inelastic rope 8, is connected with the aluminium section bar 12 of the other end with stretch cord 10.Reducing motor 7 is fixed on side aluminium section bar 12, and reducing motor 7 rotates and pulls linear slider 9.Web member 5 one end is fixed on pressure transducer, and the other end is through the gap in dividing plate 4.
Wherein image capture module comprises industrial camera 1, and moment load-on module comprises web member 5, pressure transducer 6, reducing motor 7, inelastic rope 8, linear slider 9, stretch cord 10, line slide rail 11, and all the other are workbench.
Several the parameters that the utility model can be tested, comprise back the test of nonlinear parameter of medial error, full-helm angle, torsion, slewing rate, minimum rotation dead band and steering wheel.The utility model mainly contains two kinds of working methods: one, when time medial error, full-helm angle, slewing rate, the minimum rotation dead band etc. of testing steering wheel have nothing to do with torsion, linear slider 9 rests in high order end.Two, when testing torsion, linear slider 9 slowly moves right under the pulling force of deceleration steering wheel 7, and web member 5 contacts with steering wheel 3 to be measured, and the power that applies is in the rocking arm place of steering wheel 3 to be measured.
Each parameter concrete concept and concrete testing scheme as follows:
Return medial error: steering wheel rocking arm gets back to angular error during centre position at every turn.Testing scheme: MCU sending controling instruction is to steering wheel 3 to be measured, the rocking arm hard aport thereupon of steering wheel 3 to be measured, neutral position, hard starboard three kinds of states are switched repeatedly, industrial camera 1 carries out image acquisition to steering wheel 3 to be measured, obtain the angle of getting back to steering wheel rocking arm centre position through image procossing, calculate net result.
Full-helm angle: concrete angle during steering wheel rocking arm full-helm.Testing scheme: while testing back medial error, can record steering wheel rocking arm angle at that time when steering wheel 3 full-helm to be measured with industrial camera 1.
Slewing rate: the rotational angular velocity of rocking arm during steering wheel work.Testing scheme: the number of pictures per second of setting industrial camera 1, gathers image when steering wheel rocking arm rotates to it, draw steering wheel rotational angular velocity according to the differential seat angle between two two field pictures.
Minimum rotation dead band: control signal does not make the maximum region of variation of steering wheel rocker motion.Testing scheme: control signal is changed minutely by MCU, industrial camera 1 records the angle of steering wheel 3 rocking arm to be measured, and when angle is greater than certain value, the change of its control signal is minimum dead band.
Torsion: when steering wheel is static, the power of external force when making steering wheel rocker motion apart from the place of steering wheel center of turntable 1CM.Testing scheme: under the effect of the reducing motor 7 of moment load-on module, web member 5 slowly moves right, and the power that applies is in the rocking arm of steering wheel 3 to be measured, the pressure transducer 6 of moment load-on module can feed back instant pressure data values MCU.Industrial camera 1 records the angle of steering wheel 3 rocking arm to be measured simultaneously, obtains the torsion of steering wheel when angle change is greater than setting value.
Nonlinear curve parameter: when referring to work as certain tested Parameters variation, the curve map that another parameter changes thereupon, such as pulse width and steering wheel rotational angle, voltage and torsion, relation etc. between voltage and velocity of rotation.Testing scheme: the numerical value changing a certain test parameter, records the situation of change of another parameter.
