Process for manufacturing base board of high-speed rail equipment cabin using composite material
A process for manufacturing a base board of a high-speed rail equipment cabin using a composite material is disclosed. The composite material includes: aramid honeycomb, PET foam, 3K twill carbon fiber flame retardant prepreg, unidirectional carbon fiber flame retardant prepreg, glass fiber flame retardant prepreg, aramid flame retardant prepreg, and 300 g/cm.sup.2 single component medium temperature curing blue epoxy adhesive. The process includes manufacturing a base-board main plate (1), a base-board handle (2) and two base-board sliders (3). While installation, the base-board handle (2) is stuck to one side of the base-board main plate (1), and the two base-board sliders (3) are respectively stuck to another two opposite sides of the base-board main plate (1). The weight of the base board made from the composite material is 35%-40% lower than the base board made from the aluminum alloy material, which leads to a good prospect of application.
A Panel, Support Rib and Cantrail
A side wall assembly and associated cantrail of a light mass transit vehicle, the side wall assembly may be lightweight, strong and safe and the inclusion of panels in the assembly is easily adaptable. The cantrail may be more lightweight than typical cantrails while maintaining suitable rigidity and strength required to support a roof, and associated items mounted on a roof, and securely connect to a side wall assembly of a light mass transit vehicle.
Carbody of railcar
A carbody of a railcar includes a roof bodyshell, a side bodyshell, and a cantrail. The cantrail includes: an outside plate; an inside plate arranged at a car inner side of the outside plate and spaced apart from the outside plate; and a plurality of coupling rib plates coupled to the outside plate and the inside plate and forming a plurality of triangles together with the outside plate and the inside plate. Each of the outside plate and the inside plate includes a plurality of sections each connecting apexes of the triangle. The plurality of sections of at least one of the outside plate and the inside plate include a plurality of flat plate sections. In the at least one plate, two or more adjacent flat plate sections among the plurality of flat plate sections are arranged on a straight line.
RAIL VEHICLE
Provided is a rail vehicle that can promote a weight reduction of the rail vehicle by providing a film body in a side film or a ceiling film, can ensure a large vehicle inner space, can prevent the occurrence of stains, scratches, and the like. The rail vehicle includes an underframe including a floor portion, side structures that each have a window and are erected along a longitudinal direction of the side structures at both end portions in a width direction of the underframe, and side films provided along surfaces of the side structures on a vehicle inner side. Each of the side films has a window opening portion at a portion corresponding to the window, and a window frame portion that presses a peripheral edge portion of the window opening portion toward the side structure is provided.
Mounting structure for equipment compartment bottom plate
A mounting structure for equipment compartment bottom plate is provided. The bottom plate is detachably connected to a skeleton boundary beam of the equipment compartment. A sliding rail is fixedly connected to a side of the bottom plate where the bottom plate is lap-jointed to a skeleton lateral beam of the equipment compartment. One of the sliding rail and the skeleton lateral beam is provided with a recess and the other is provided with a protrusion engaged with the recess. In the mounting structure, the connection of the bottom plate and the skeleton lateral beam is achieved by the engagement of the recess and the protrusion. Therefore, connecting pieces for connecting the bottom plate and the skeleton lateral beam are removed and the number of the connecting pieces is significantly reduced.
Aluminum material having improved precipitation hardening
An aluminum material for producing light-weight components includes aluminum (Al), scandium (Sc), zirconium (Zr) and ytterbium (Yb), where a weight ratio of scandium (Sc) to zirconium (Zr) to ytterbium (Yb) [Sc/Zr/Yb] is in a range from 10/5/2.5 to 10/2.5/1.25.
RAILWAY VEHICLE BODY STRUCTURE AND MANUFACTURING PROCESS THEREOF
Disclosed is a body structure for a rail vehicle, wherein the body structure includes: a frame, which includes at least one support element made at least predominantly of steel alloy; and at least one equipment element made predominantly of aluminum alloy, and including at least one first plate having at least one longitudinal edge and a first surface delimited by the longitudinal edge. The body structure is wherein it further includes at least one longitudinal batten of steel alloy, which is integral with the support element, wherein the longitudinal batten is fixed flat to the first face by way of friction melt bonding.
Reinforcement structure and process for reinforcement of a panel element
A method for stiffening a sheet element is provided. The method includes a first step of providing stiffening modules each having a flange and at least one web. The stiffening modules are attached to the sheet element sequentially along a load path, where the stiffening modules are connected to each other via their respective flanges for a positive, frictional and/or materially bonded connection to form a stiffening structure, such that the stiffening modules have a combined effect, specifically stiffening and reinforcing the sheet element. A stiffening structure for a sheet element is also provided that has a plurality of stiffening modules arranged sequentially, and to a stiffening system that includes a stiffening structure and a sheet element.
Wall Arrangement For A Vehicle
A wall configuration for a vehicle includes a sandwich panel having a core layer provided on either side with a respective metallic cover layer. Edge portions of the cover layers on at least one side of the sandwich panel project from an end face of the core layer. A metal connecting profile has an edge portion inserted into an interspace between the two projecting edge portions of the cover layers. Inner sides of the projecting edge portions of the cover layers are each structurally connected to an associated outer surface of the inserted edge portion of the connecting profile by a respective structural adhesive or bonding layer. At least one of the projecting edge portions of the cover layers is electrically conductively connected to the abutting the edge portion of the connecting profile by a weld seam at a distance from the adhesive-bonding layer.
Personalised elevated urban transport
A bidirectional overhead urban transport (TUEP) for a large transportation capacity, which is suspended over a series of poles, without interfering with the traffic of vehicles and pedestrians surface, which is characterized by having a continuum of autonomous cabins circulating about a tubular track suspended by static wires hanging from the poles. The system has overhead stations for passengers, by which access is given to the suspended cabins, moved by autonomous and independent electric motors which rotate a drive pulley rolling on the upper back of a horizontal tubular track raised or inclined according to the topography of the ground. The peculiarity of this transport system is that each of the cabins that are only for two passengers, travels directly to a destination station, where is diverted from the main flow to a station, so it is not necessary to stop the main flow of cabins, which results in that although circulating at low to moderate speed, the time required to travel is reduced.
