Description
Technical field
The present invention relates to a kind of aluminum matrix composite rail vehicles, belong to rail traffic vehicles technical field.
Background technique
With the development of modern science and technology, track train vehicle becomes more the performance requirements such as lightweight, vibration sound insulation
Add harshness, especially in the non-tunnel section of urban inner, the requirement to vehicle wheel-rail noise is higher.In railway train body steel knot
Structure field, each research unit and manufacturing firm are continuously attempting to improve performance indicator with new material always.
In recent years, carbon fiber body construction is the popular domain of car body lightweight research.Application No. is
The patent of CN201520712628.4, CN201611093476.X, CN201620863664.5 all refer to carbon fibre composite
Body construction, carbon fiber itself have the characteristics that high specific strength, specific modulus, corrosion resistance and good, are car body lightweighting materials
One of one main source.But carbon fiber typically as sandwich panel application on the car body, be arranged between panel
The core material of porous foam material production, panel generally use adhesive means to connect with sandwich, and the structure is in receiving bending load
Or connection surface easily occurs to shear peeling after vibrating repeatedly.Glue is generallyd use using the connection between the component of sandwich
Bonding or viscose glue such as rivet or are bolted at the mixed forms, are vehicle car body weakest links, often without it is enough just
Degree resists excessive vibration.This weakness can avoid using large-scale integral shaping method, such as application No. is
CN201611096406 patent of invention integrates roof and side wall, but production cost further steeply rises.In order to
Reduce cost and production difficulty, the measure that can be taken the lower part of some intensity requirements using carbon fiber structural or
Aluminium sheet+laminboard layer composite material sandwich structure, with body frame structure using Nian Jie or be bolted, such as application No. is
The utility model patent scheme of CN201420755293, but the connecting portion of this structure is still weak spot.In order into one
Step reduces the usage amount of the adhesive between car body main structure, improves the durable reliability of structure, application No. is EP1982827A2
Patent increase bindiny mechanism in sandwich two sides, i.e., between sandwich and bindiny mechanism use welding manner, connection
Mechanism and car body other structures also use welding manner.But the sandwich of the sandwich and panel are stratified forms, are usually adopted
It is connected with adhesive means, complex load power is transmitted and born at the two joint face, without thoroughly solution durability and reliably
Property problem.
In addition, foamed aluminium is since it has the function of light weight, intensity height, fire prevention, sound insulation, sound absorption, noise reduction, heat-insulated etc.,

Erosion, long service life, damping property are good；Compared with plank, vibration can reduce an order of magnitude；It is close compared with aluminum honeycomb panel
Degree is lower, and tensile strength improves an order of magnitude.But current foamed aluminium is mainly applied to the sandwich material of sandwich
In vehicle (structure as shown in Fig. 1 in " application of the foamed aluminium on city railway vehicle " text), sandwich and panel (carbon fiber,
Aluminium sheet etc.) generally connected using adhesive means, and be in stratified form, it to be transmitted at the two joint face and bear complex load
Power, without thoroughly solving durability and integrity problem.
In recent years, in-situ nano ceramic particle reinforced aluminium base composite material (i.e. nano ceramics aluminium alloy, also referred to as pottery aluminium)
Technology of preparing achieves breakthrough development, and application No. is the patents of invention of CN201711114899.X, passes through nano particle
Orowan reinforcing, refined crystalline strengthening, nanometer reinforcement toughening and dispersion-strengtherning, damping effect and the rare earth of nanometer precipitated phase itself
Refinement and rotten effect effect, break the inverted relationship of strong plasticity, obtain strong plasticity, impact resistance and fatigue resistance and
It can extrude molding aluminum matrix composite.One kind, which is disclosed, application No. is the patent of invention of CN201810321256.0 passes through stirring
The stirring-head of friction welding (FW) is stirred the method for realizing nano particle Dispersed precipitate, the connection between aluminum matrix composite component
Provide more preferably method.In conclusion by increasing nano-ceramic particle in aluminium alloy, the new material of acquisition is being maintained
The superperformance of protocorm while having high-strength and high-plasticity, also has high specific stiffness and specific modulus, further to car body
Lightweight brings hope.But the further lightweight of car body frequently can lead to that profile gusset is thinning, and density becomes smaller, if big face
Product uses traditional arc welding, it will brings great difficulty to the weld industry of car body manufacturing process.
How the alumina-base materials such as high performance nano ceramics aluminium alloy and foamed aluminium to be applied in car body, to replace certain
The carbon fiber structural at a little positions improves the intensity of linkage interface and durability and reliability between structural member inside and component, together
Shi Zengqiang car body light weight effect improves the vibration and noise reducing performance of vehicle, is that the present invention will solve the problems, such as.
