In the present embodiment, test result shows：The Y-direction first-order modal intrinsic frequency of steering 30 is from original 28.8Hz
Variation is 32Hz, to larger with the second order driving frequency 25.67Hz gaps of engine；And therefore steering wheel 31 is vibrated from original
0.49m/s2It is reduced to 0.19m/s2。
More than, it is arranged in the first left region 111, the second left region 113, the first right region 121 and second by increasing
The lateral reinforcing plate 130 in right region 123 changes the architectural characteristic of steering column mounting bracket 100, increases steering column installation
The lateral stiffness of holder 100, to change the Y-direction Modal frequency of steering 30 so that the second order of itself and engine swashs
Frequency decoupling is encouraged, to which steering wheel 31 vibrates problems of too when solving idle engine and air-conditioning unlatching.
In addition, the test result and/or software analysis result such as following table of multiple comparative examples, wherein comparative example 1
Using technological means 1；Comparative example 2 is combined using technological means 2 to technological means 10；Comparative example 3 uses technology hand
Section 3 to technological means 6 combines；Comparative example 4 uses technological means 11.In the structure of the description above in association with Fig. 1 to Figure 17
On the basis of, in each technological means, only structure difference is illustrated.
" vertical support beam ", " cross reinforcing beam " are not shown in figure in upper table；Vertical support beam is generally perpendicular to instrument
Dial plate main body of cross-beam 200, one end of vertical support beam are welded with instrument panel beam main body 200, the other end of vertical support beam with
Car body vehicle body connects；It is welded respectively with instrument panel beam main body 200 and vertical support beam at the both ends of cross reinforcing beam.
The test result of comparative example 1 is that the Y-direction first-order modal intrinsic frequency of steering increases 1.5Hz, software point
It is that frequency increases 1.2Hz to analyse result；The software analysis result of comparative example 2 is that frequency increases 0.4Hz；Comparative example 3
Test result is that frequency increases 0.75Hz；The software analysis result of comparative example 4 is that frequency increases 0.25Hz.
Comparison it is found that the lateral reinforcing plate of 1.5mm thickness although carry high-frequency ability not as good as 2mm thickness lateral reinforcing plate,
But comparative example 1 is apparent compared to comparative example 2-4 superiority, that is, increases the scheme of lateral reinforcing plate compared to other
Technological means or the scheme superiority of other technologies means combination are apparent.
