The kinds of drive such as person's central shaft chain wheel, hub driving is rational in infrastructure compact, and small volume is in light weight, efficiency high.
Electric bicycle can be influenceed in road traveling by the dynamic loading changed over time, when dynamic loading is larger or frequency with
When certain first natural frequency of bicycle is close, it may occur that resonance, serious strength failure is caused, therefore in main car frame without constraint
In the case of wake up with a start model analysis, the first six rank mode is almost 0, referred to as rigid mode, and the dynamic loading of electric bicycle is analyzed
Do not have much affect, due to causing the frequency that the excitation that vehicle frame resonates is mainly lower-order, the total vibration of structure is by each rank frequency
Rate is formed by stacking, therefore low order mode influence is bigger, therefore the mode extracted is the 7th rank mode to the tenth second-order modal.
7th rank (fz=78.83Hz) it is buckling of the vehicle frame along Y-axis, it is Seat stay at maximum distortion；8th rank (fz
=108.22Hz) it is bending of the vehicle frame along Z axis, it is back vent and wheel junction at maximum distortion longitudinal direction；9th rank (fz=
135.15Hz) it is transverse curvature of the vehicle frame along Y-axis, is foreboard at maximum distortion；Tenth rank (fz=215.48Hz) it is vehicle frame along Z
The bending of axle, it is foreboard and rear support stand at maximum distortion；Tenth single order (fz=326.89Hz) it is bending of the vehicle frame along Y-axis,
It is rear support stand at maximum distortion；Tenth second order (fz=355.26Hz) it is bending of the vehicle frame along Z axis, it is foreboard at maximum distortion
And rear bearing sheet.
It can be found that foreboard and rear bearing sheet are the regions for being easiest to occur resonance deformation, that is, solar panel is installed
Position, once resonating, connector can be caused to fail, destroy the structure of solar panel.When solar bicycle travels
When on the way, the temporal frequency formula of input is：F=v Ω, it is the product of speed and the spatial frequency of road roughness, works as car
Speed is：V=3.6LwDuring f (km/h), resonance occurs in electric bicycle, and it is as follows that I crosses the length actual measurement of road roughness wavelength：
Solar bicycle average speed per hour is 20~30km/h, therefore the intrinsic frequency of structure not should be：17.36~
26.04HZ, because the modal frequency of vehicle frame the 7th is 78.83HZ, therefore the excitation of road roughness is unlikely to cause resonance, too
Although positive energy plate installation site is the place of resonance most serious, but its stability is still can guarantee that under normally travel.
Gear mechanism is removed by the improvement again to solar tracking apparatus, spiral is driven by motor by the present invention
Pivot direct drive solar panels are moved, and improve the conversion ratio of solar panel, while reduce volume and weight,
It is adapted to mount on bicycle；Suitable vehicle body, handlebar width, handlebar elevation angle etc. are provided with according to ergonomics so that ride
It is more comfortable；The position of solar panel, battery, motor etc. is placed so that vehicle body is more exquisite attractive in appearance, maximizes
