Abstract
The invention discloses a passenger car steering wheel single mode testing device which comprises a base, a steering wheel installation bracket, base fixing bolts, base fixing nuts, a washer and a steering wheel fastening nut, wherein the base is fixed on a floor sliding groove through the base fixing bolts and the base fixing nuts, the steering wheel installation bracket is fixed on the base, and the steering wheel installation bracket is equipped with the steering wheel fastening nut used for installing and fastening a steering wheel. The passenger car steering wheel single mode testing device of the invention is suitable for testing a single mode of a steering wheel. In order to improve the testing precision, the installation position of the base is fixed, the grounding mode is not less than 1000Hz, and the installation angle of the steering wheel is unchanged. Normalization and consistency of testing are ensured, the influence of the steering wheel installation angle and the base installation stiffness is eliminated, and the influence of human factors to test results is also eliminated.
Description
Technical field
The present invention relates to automobile chassis vibration and noise test technical field, be specifically related to a kind of passenger car bearing circle monomer mode proving installation.
Background technology
Along with improving constantly that user vehicle requires car comfort, auto NVH is subject to numerous auto vendors and more and more payes attention to, and the vibration of the bearing circle directly contacting with human body is the emphasis that auto NVH is paid close attention to.Bearing circle monomer mode exerts an influence to steering mode, thereby affects the level of vibration of bearing circle.Therefore, direction of measurement dish monomer mode the other side is significant to disc vibration control.
The test of vehicle steering monomer needs a kind of fixture, can be applicable on the one hand the installation of polytype passenger car bearing circle, is beneficial to the excitation of power hammer; Make on the other hand bearing circle in ground state, the accuracy of warranty test, wants standardization and the consistance of warranty test simultaneously.
Current most of automaker only calibrates steering mode, directly the mode of steering is tested with targeting device (as LMS), do not need frock, bearing circle monomer mode is not calibrated, have steering mode risk not up to standard.
Summary of the invention
The object of this invention is to provide the device of a set of measurement direction dish monomer mode, its object is measurement direction dish monomer mode.
Passenger car bearing circle monomer mode proving installation of the present invention comprises base, bearing circle mounting bracket, base set bolt, base hold-down nut, pad and bearing circle clamp nut, described base is fixed on the chute of floor by base set bolt and base hold-down nut, bearing circle mounting bracket is fixed on base, and the bearing circle clamp nut that fastening bearing circle is installed is housed on it.
Further, the position that described bearing circle mounting bracket is connected with bearing circle is spline structure, with the spline tabling of bearing circle.On bearing circle mounting bracket, be provided with in addition bearing circle fastening gasket, coordinate bearing circle clamp nut that fastening bearing circle is installed.
The present invention is applicable to measurement direction dish monomer mode, in order to improve measuring accuracy, floor installation position is fixed, ground connection mode is not less than 1000Hz, bearing circle setting angle is constant, ensure standardization and the consistance of test, got rid of the impact of bearing circle setting angle and floor installation rigidity, also got rid of the impact that human factor produces test result.
Compared to the prior art, the present invention has the following advantages:
1, use this frock to calibrate bearing circle monomer, reduced steering mode risk not up to standard.
2, this device, simple in structure, easy to operation, fixing mounting means has ensured reliability and the accuracy of test.
This device, for automobile production producer, can be calibrated bearing circle monomer mode, is conducive to goal-setting and the decomposition of steering.This device, for bearing circle manufacturer, can detect the situation up to standard of bearing circle, thereby improves the qualification rate of product.
Brief description of the drawings
Fig. 1 is bearing circle monomer mode proving installation decomposing schematic representation;
Fig. 2 is base and floor chute scheme of installation;
Fig. 3 is bearing circle excitation schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is passenger car bearing circle monomer mode proving installation decomposing schematic representation of the present invention, comprises base 1, is fixed on bearing circle mounting bracket on base 2, two base set bolts 3, two base hold-down nuts 4, pad 5, bearing circle clamp nut 6 and floor chutes 7.Base 1 is fixed on floor chute 7 by base set bolt 3 and base hold-down nut 4, and floor chute 7 is close in base 1 bottom surface, and base 1 thickness is 30mm.Bearing circle mounting bracket 2 is fixed on base 1, and bearing circle mounting bracket 2 is that many steps are cylindric, and it is highly 80mm.Bearing circle clamp nut 6 and bearing circle fastening gasket 5 that fastening bearing circle is installed are housed on bearing circle mounting bracket 2.The position being connected with bearing circle to dish mounting bracket 2 is spline structure, with the spline tabling of bearing circle.
Method of testing:
First, base 1 is arranged on floor chute 7, makes base groove opening and floor chute register.
Further, as shown in Figures 2 and 3, from both ends open, base set bolt 3 is packed into opening, rotation makes its clamping, then loads onto base hold-down nut 4, is tightened with torque spanner, and its value is 200 Nmm.
Further, bearing circle is mounted on bearing circle mounting bracket 2, rotation agrees with spline between the two completely.
Further, load onto pad 5 on bearing circle mounting bracket, screw on bearing circle clamp nut 6, tightened with torque spanner, its value is 100 Nmm.
Finally, as shown in Figure 3, use mode testing apparatus (as LMS) to test bearing circle monomer mode, the firmly hammer both direction of excitation orientation dish (Z-direction and X to) respectively, obtains mode and the vibration shape of bearing circle.
