Description
Technical field
The utility model patent is related to the frock for simulating subscale test, especially a kind of simulation bullet train brake pad
Braking effect frock.
Background technology
At present, with the fast development of Chinese large-sized carrier technology, top load brake gear application is more and more.With
When brake gear security and stability become of crucial importance.Brake gear must reach corresponding mechanical property, frictional behaviour will
Ask.And during research and development friction material, every group of sample is both needed to the mark by relevant departments' certification
Quasi- bench test is verified.Every time the testing expenses of standard stand are expensive, and detection cycle is very long, through multiple batches of detection after
High cost can be then caused, feasibility is poor；The quality testing of later stage batch production simultaneously will also result in cost increase；Therefore should
Digital simulation is carried out by subscale test stand.
Common dynamic analog subscale test frock is all friction pair scheme of the annulus to annulus, but for bullet train
For the materials such as brake pad, the brake block of Super Car, rub as its actual friction braking material is " piece is to disk "
Mode of braking is wiped, and therefore which contracts and also corresponding modification should be made according to its mode of braking than simulated test frock.
Utility model content
For the problems of the prior art, the purpose of this utility model is a kind of for friction braking material " piece is to disk "
Friction catch mode and the corresponding dynamic analog subscale test frock that provides, to be suitable under " piece is to disk " damped condition
Thermic load and the distribution of thermal stress.The frock can simulate the braking effect of bullet train brake pad during friction test
Really, reach expected test effect, and test data coincide with bench test parameter, can high degree reduction experimentation cost.
In order to achieve the above object, the technical solution of the utility model is：
A kind of dynamic analog subscale test frock, it is characterised in that：The frock includes installing contracting than powder test block
Rebound, and, the base plate of fixed rebound, the base of fixed base plate, the base are connected to test by keyway thereon
With in rotary shaft, wherein, the groove for contracting being installed than powder test block is evenly equipped with rebound axle center as the center of circle on described rebound
Hole.
Further, described rebound is connected by screw and is fixed on base plate, and described base plate is connected by screw
It is fixed on base.
Further, it is interference fits between the slotted eye during described contracting is than powder test block and rebound, and after installing
Contracting more outwardly than the relative rebound of powder test block.
Further, the contracting is circular or square than powder test block, and corresponding slotted eye is also circular or square.
Further, described slotted eye is evenly equipped with three with the axle center of rebound as the center of circle.
Compared with prior art, the dynamic analog subscale test frock of the utility model offer is simple and reliable for structure,
Its using round steel disk with multiple contracting than powder test block to rubbing by the way of, operating condition of test is more life-like, and its test principle is：1) make
The brake percentage pressure of dynamic material surface is consistent with actual damped condition；2) linear velocity of brake material is consistent with actual condition；3) make
The absorption work(of dynamic friction pair unit area is consistent.The frock takes into full account that actual damped condition is consistent with simulation subscale test
Property, using the frock of this programme, by corresponding scaling calculation, standardization subscale test frock is converted into by jack horse test bed,
Ensure the stability of batch brake gear of often dispatching from the factory by corresponding computational methods, and performance is consistent with bench test guarantee.Should
Dynamic analog subscale test frock is applied in the research and development of bullet train brake pad, reached with code test stand 95% with
On degree of conformity, considerably beyond the degree of conformity of common frock 70～75%, be suitable for wide popularization and application.
Description of the drawings
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or accompanying drawing to be used is briefly described needed for description of the prior art, it should be apparent that, drawings in the following description are only

Specific embodiment
With reference to the accompanying drawings and examples the utility model is further described.
As shown in drawings, a kind of dynamic analog subscale test frock, including installing rebound of the contracting than powder test block 4
3, rebound 3 is connected on a base plate 2 by screw 6, and base plate 2 is connected by screw and is fixed on base 1, and base 1 passes through
Keyway 8 thereon is connected in test rotary shaft, wherein, is evenly equipped with 3 axle center of rebound as the center of circle on described rebound 3
Slotted eye 7 of the contracting than powder test block 4 is installed, for guarantee test authenticity effect, and heat dispersion in process of the test, overall
Structural strength performance, slotted eye 7 uniformly preferably have three with the axle center of rebound 3 as the center of circle, contract than powder test block 4 for circular or
Square, corresponding slotted eye 7 also for circular or square, or for other corresponding regular, irregular geometries, contracting
Than being interference fits between the slotted eye 7 in powder test block 4 and rebound 3, its relative stability is packed, be not in friction examination
Play phenomenon during testing, and the contracting after installing is more outwardly than 4 relative rebound 3 of powder test block, is easy to test friction.
The frock is can also be used in the test of top load brake gear, during concrete test application, by contracting than powder test block 4
Or in rebound 3 of other test block interference fits in the frock, then by the keyway 8 on base 1 by the work
