By the interconnection of the middle frames, the structure of the middle frame can connect the vertical beams and composite boards to form a whole, so as to strength the rigidity of the vehicle body, so that the length of the middle frame profile material does not exceed four meters each segment, thereby solving the problem that the abnormal profile materials such as upper chord beam, lower chord beam, vertical beam on windows, vertical beam under windows in domestic production can not exceed 15m length and the problem about ultra-long profile material transportation, manufacture and molding, and correction.

Description

Maglev vehicle car body center

Technical field

The utility model relates to mount structure in a kind of magnetic suspension train body.

Technical background

At present, Yan Jiu high-speed maglev train in order to overcome the resistance of aerodynamic loading, is considered the streamline profile of car body and the sound insulation and noise reduction of body construction in the world, and the magnetic suspension train car body is designed to more than the 20 meter long body construction of all-in-one-piece that link up.Therefore, the passenger on the car can only be about the car door of car end both sides, and is inconvenient up and down.In the manufacturing, it need reach on more than the 20 meter long beam that winds up, lower edge beam, window special-shaped section bar such as longeron under longeron, the window.Not only to be subjected to the restriction of working condition and production site, and bring difficulty for manufacturing moulding, correction and the transportation of overlength section bar.Be subjected to the restriction of domestic production condition, on the beam that winds up, lower edge beam, the window under longeron, the window special-shaped section bar such as longeron all can't to surpass 15m long.

Summary of the invention

The problem that the utility model exists at above-mentioned prior art, a kind of modern modular design that meets is provided, can satisfies intensity, rigidity requirement, again can expendable weight, profile length is no more than 4m for every section, mount structure in the maglev vehicle car body that can be connected as a single entity longeron, composite plate structure.

In order to reach above-mentioned purpose of the present utility model, a kind of maglev vehicle car body center that the utility model provides, comprise head and the tail bonded assembly abnormity section bar, it is characterized in that, the center framework is divided into leading portion, stage casing and back segment three parts with the floating car body of described magnetic, the center framework that is connected in car body middle part couples together longitudinal stress beam and composite plate structure and constitutes complete car body, and by the envelope edge section bar 18 of frame section 17 in the bonded assembly of both sides, and form by the core 19 that inner cover plate 20 and outer cover plate 16 clamping connections constitute interlayer.

Described in the utility model, described center framework can be connected to form by longeron joint, longitudinal floor beam joint etc. under longeron joint, the window on center top section bar, center commentaries on classics segmental arc section bar, center side segment type material, center bottom section bar, the beam splice that winds up, lower edge beam splice, the window.

The utlity model has following beneficial effect.

The middle mount structure that the utility model adopts, more than 20 meters long body constructions are divided into three, and reasonably the longitudinal stress beam is arranged and to the loss of weight design of beam, meet modern modular design, simultaneously also can be according to user's needs, can change the structure between the center into automobile door structure soon, satisfy the passenger getting on/off needs.Dock by center, mount structure is connected as a single entity longeron, composite plate structure well in not only making, increase the rigidity of body construction, and make center structural shapes length be no more than 4m for every section, solve the domestic production special-shaped section bar such as longeron that winds up under longeron on beam, lower edge beam, the window, the window simultaneously and can't surpass the long problem of 15m, and the transportation of overlength section bar, made moulding, calibration problem.

The specific embodiment

Fig. 1, Fig. 2 have described the utility model the floating car body of described magnetic have been divided into leading portion, stage casing and back segment three parts, longitudinal stress beam and composite plate structure are coupled together constitute complete car body.The center framework that is connected in the car body middle part is mainly connected to form by longeron joint 5, center side segment type material 6, lower edge beam splice 7, center bottom section bar 8, longitudinal floor beam joint 9 under longeron joint 4, the window on center top section bar 1, the beam splice 2 that winds up, center commentaries on classics segmental arc section bar 3, the window.Under the situation that proof strength, rigidity requirement and profile are coordinated, be the weight of mount structure in alleviating, adopt aluminum alloy extrusion section bar, steel joint.The section bar reasonable in design and the structure of joint are determined the section form and the profile of section bar, arrange muscle rib position in the cross section, and its thickness of optimized choice, thereby guarantee to be connected with the car body composite plate structure coordination and alleviate structural weight; Joint not only couples together horizontal middle frame section, and be that each beam couples together with the longitudinal stress member, it is the key position that the whole locomotive body structural load are transmitted, therefore, select the material of high strength rigidity during joint design, shape is by corresponding frame, the decision of beam shape in it, and profile is then determined by the gap between composite panel and the beam, adopts the single face pumping nail to connect.Center 17 connects and composes body construction with body construction leading portion, stage casing and back segment three part of module.

In the middle mount structure that Fig. 1, Fig. 2 describe, the center that bears flexural load is connected to form by following parts, and center top section bar 1 wherein shown in Figure 3 is connected in the beam 10 that winds up, center by the beam splice 2 that winds up shown in Figure 4 changes segmental arc and change segmental arc section bar 3 by center shown in Figure 3 and be connected on wind up beam 10 and the window between the longeron 11.Side window 12 is connected on the upper and lower window of side window under the longeron 11 and window between the longeron 13 by longeron joint 5 under longeron joint 4 on the window shown in Figure 5 and the window shown in Figure 6, center side segment type material 6 shown in Figure 3 by longeron joint 5 under the window and lower edge beam splice 7 be connected between longeron 13 under the window and the lower edge beam splice 14 shown in Figure 7, middle frame bottom forms with longitudinal floor beam 15 by center bottom section bar 8 shown in Figure 3 and longitudinal floor beam joint 9 shown in Figure 8.Forming the bonded assembly center thus should link to each other with beam, links to each other with middle circle section again, connected by the joint butt joint of longitudinal loading.The shape of joint determines its shape by corresponding frame, beam.In the present embodiment, longeron 13 (left-right symmetric), floor bearer 15 (left-right symmetric) under longeron 11 (left-right symmetric), the window on the beam 10 (left-right symmetric) that winds up, lower edge beam 14 (left-right symmetric), the window.For satisfying intensity, rigidity requirement, requirement that again can expendable weight, except that selecting special-shaped extruded aluminium section for use, also adopted in shape mainly in the longitudinal cross-section of described beam by geometry combinations such as triangle, trapezoidal and rectangle forms lightening hole reinforced rib groove or rib design.The design-calculated composite panel is made up of last covering, following covering, sandwich foam, envelope edge section bar etc.So that it has certain intensity, rigidity, have sound insulation and noise reduction, heat insulating function again and can alleviate body construction weight.

Among Fig. 9, connect the envelope edge section bar 18 of the center framework at middle part, car body front and back end, and connect to form by core 19 typical cases that inner cover plate 20 and outer cover plate 16 clamping connections constitute interlayer by frame section 17 in the bonded assembly of both sides.
