Abstract
The invention discloses a vehicle body structure and method for improving the outside corridor locomotive modal frequency. The vehicle body structure comprises a vehicle body and a side wall frame. The side wall frame is welded and fixed to the vehicle body. The side wall frame sequentially comprises a storage battery chamber frame body, an electrical chamber frame body and a power chamber frame body from left to right. A crossed inclined supporting structure is installed on the storage battery chamber frame body and the power chamber frame body. The vehicle body structure is simple in structure and reasonable in design, and the stability and torsion resistance of the vehicle body can be effectively enhanced; by means of the vehicle body structure, the locomotive body first-order vertical bending modal frequency is improved by 41.5% and is improved from 4.79 Hz to 6.78 Hz, the bogie nodding frequency of 5 Hz is completely avoided, and the probability of locomotive resonance phenomenon is greatly decreased; the crossed inclined supporting structure is easy to detach, and locomotive facility installation and maintenance are facilitated.
Description
Technical field
The present invention relates to a kind of Locomotive Carbody Structure, particularly relate to a kind of body construction of outer corridor locomotive model frequency.
Background technology
There is resonance and very easily endurance failure caused to locomotive in locomotive.In order to avoid the generation of resonance effect, require that the locomotive car body single order curved model frequency that hangs down must be avoided bogie truck and to nod frequency in the design.The existing outer corridor locomotive car body single order curved model frequency that hangs down is generally on the low side, it is very close that this frequency is generally about 4.79Hz and bogie truck frequency (being generally about 5Hz) of nodding, be easy to cause resonance, therefore must improve the model frequency of car body, this also becomes a difficult point of outer corridor locomotive car body design.
How to solve the problems of the technologies described above the direction becoming these those skilled in the art and make great efforts.
Summary of the invention
Object of the present invention is just to provide a kind of body construction improving outer corridor locomotive model frequency, can solve the weak point that prior art exists completely.
Object of the present invention is realized by following technical proposals:
Improve a body construction for outer corridor locomotive model frequency, comprise car body and side wall framework, described side wall frame welding is fixed on car body.
Further, described side wall framework is followed successively by battery room framework, electric panel room framework and power room framework from left to right, and battery room framework and power room framework install cross inclined support structure.
Further, the both sides of described battery room framework are 2 row's rectangle frames, in each rectangle frame, all install cross inclined support structure.
Further, the both sides of described power room framework are row's rectangle frame respectively, in each rectangle frame, all install cross inclined support structure.
Further, described cross inclined support structure comprises 2 box beam, and 2 box beam are installed along rectangle frame diagonal angle, and the two ends of box beam are connected with rectangle frame is detachable.
Improve a method for outer corridor locomotive model frequency, side wall frame welding is fixed on car body, and on side wall framework, cross inclined support structure is installed.
Further, described side wall framework is followed successively by battery room framework, electric panel room framework and power room framework from left to right, and battery room framework and power room framework install cross inclined support structure.
Further, the both sides of described battery room framework are 2 row's rectangle frames, in each rectangle frame, all install cross inclined support structure.
Further, the both sides of described power room framework are row's rectangle frame respectively, in each rectangle frame, all install cross inclined support structure.
Further, described cross inclined support structure comprises 2 box beam, and 2 box beam are installed along rectangle frame diagonal angle, and the two ends of box beam are connected with rectangle frame is detachable.
Compared with prior art, beneficial effect of the present invention is:
1. structure is simple, reasonable in design, effectively can strengthen stability and the torsional property of car body;
2. this body construction improves locomotive car body single order and to hang down curved model frequency 41.5%, is increased to 6.78Hz by 4.79Hz, avoids bogie truck completely and to nod frequency (5Hz), considerably reduce locomotive resonance effect odds;
3. cross diagonal brace is easy to dismounting, facilitates locomotive erection of equipment and maintaining.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
See shown in Fig. 1 to Fig. 6, a kind of body construction improving outer corridor locomotive model frequency, comprises car body and side wall framework 1, and described side wall framework 1 is weldingly fixed on car body.Described side wall framework 1 is followed successively by battery room framework 2, electric panel room framework 3 and power room framework 4 from left to right, installs cross inclined support structure 5 in the side of battery room framework 2 and power room framework 4.
The both sides of described battery room framework 2 are 2 row's rectangle frames 21, and each arranges 5 rectangle frames 21, in each rectangle frame 21, all install cross inclined support structure 5.
The both sides of described power room framework 4 are a row 3 rectangle frames 41 respectively, in each rectangle frame 41, all install cross inclined support structure 5.
Described cross inclined support structure 5 comprises 2 box beam, and 2 box beam are installed along rectangle frame diagonal angle to be formed and intersected, and the two ends of box beam are connected by screw 6 is detachable with rectangle frame.Described box beam is formed by the thick channel-section steel of 3mm and the thick cover plate combination of 5mm, and forming cross-sectional plane is the box beam of rectangle.
A kind of method improving outer corridor locomotive model frequency, side wall framework 1 is weldingly fixed on car body, described side wall framework 1 is followed successively by battery room framework 2, electric panel room framework 3 and power room framework 4 from left to right, installs cross inclined support structure 5 in the side of battery room framework 2 and power room framework 4.
The both sides of described battery room framework 2 are 2 row's rectangle frames 21, and each row has 5 rectangle frames 21, in each rectangle frame 21, all install cross inclined support structure 5.The both sides of described power room framework 4 are a row 3 rectangle frames 41 respectively, in each rectangle frame 41, all install cross inclined support structure 5.Described cross inclined support structure 5 comprises 2 box beam, and 2 box beam are installed along rectangle frame diagonal angle to be formed and intersected, and the two ends of box beam are connected by screw is detachable with rectangle frame.
For the ease of dismounting and easy to maintenance, the side wall of existing locomotive is all designed to bascule, do not participate in carry.And side wall frame welding is fixed on car body by the present invention, the curved the model frequency 41.5% thus single order that improve locomotive car body hangs down, be increased to 6.78Hz by 4.79Hz, avoid bogie truck completely and to nod frequency (5Hz), considerably reduce locomotive resonance effect odds.Because electric panel room generally overhauls relatively more frequent, for the ease of dismounting, so electric panel room framework two sides do not need to install cross inclined support structure.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
