Background technology
In the occasion that much there is mechanical shock（Such as emitter, automobile suspension system）Buffer is required for, is buffered
The shock resistance of device needs to carry out experiment test, and this is must just to use bumper property experimental provision.
Existing bumper property experimental provision is generally drop hammer type or fluid pressure type, and they are operated in the relatively low bar of frequency
Tested under part, it is impossible to obtain the High Frequency Dynamic of buffer.And the impulsive force duration produced in emitter is short
（0.3ms or so）, power width it is big（Generally higher than 30KN）, it is therefore desirable to buffer has good high frequency performance.
The content of the invention
It is an object of the invention to provide a kind of tubular experimental provision for measuring buffer shock resistance, overcome existing
Buffer is tested under conditions of frequency is relatively low, it is impossible to the problem of obtaining the High Frequency Dynamic of buffer.
The technical solution for realizing the object of the invention is：A kind of tubular experiment dress for measuring buffer shock resistance
Put, including sleeve, outer barrel, chassis, barrel, M buffer mounting stand and N number of guide rail, wherein M >=2,2≤N≤8, outer barrel bottom
It is connected with chassis, barrel is arranged in outer barrel, barrel outer wall is cased with ring flange, long axis direction of N number of guide rail along barrel is set,
Even to be distributed in outer tube inner wall, the ring flange coordinates with guide clearance, slided along guide rail；M buffer mounting stand is all along outer barrel
Be connected to being uniformly distributed, and with outer barrel, sleeve outer wall is provided with P journal stirrup, P=M, sleeve with it is connected at the top of barrel, and sleeve is located at
Above outer barrel, the journal stirrup of buffer one end to be measured and sleeve is connected, and the other end is connected with buffer mounting stand.
The bottom plate of the buffer mounting stand is mounting surface, and mounting surface band is cambered, is coordinated with outer barrel；Buffer mounting stand
Journal stirrup is provided with, journal stirrup is provided with through hole, is connected with one end of buffer to be measured, and reinforcement is provided between journal stirrup and bottom plate.
The barrel is cylinder, and top has an annular boss, is coordinated by boss and sleeve gap, by pressure transmission
To buffer to be measured.
The outer barrel is cylinder, avoids guide rail on outer barrel and buffer mounting stand opens some lightening holes.
Compared with prior art, its remarkable advantage is the present invention：（1）Simple and reliable for structure, production cost is low, and compared with
The good simulation impact condition of emitter；（2）The device can install the buffer in most of length and diameter range,
With well adapting to property.

Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
With reference to Fig. 1 to Fig. 5, a kind of tubular experimental provision of measurement buffer shock resistance, including sleeve 1, outer barrel 2,
Chassis 3, barrel 4,2 buffer mounting stands 5 and 4 guide rails 6, the bottom of outer barrel 2 are connected with chassis 3, and both are integrally welded, body
Pipe 4 is arranged in outer barrel 2, and the outer wall of barrel 4 is forward and backward to be respectively cased with 1 ring flange, and long axis direction of 4 guide rails 6 along barrel 4 is set,
The inwall of outer barrel 2 is evenly distributed on, the ring flange coordinates with the gap of guide rail 6, slided along guide rail 6.2 edges of buffer mounting stand 5
The circumference of the outer wall of outer barrel 2 is uniformly distributed, and is connected by bolt and outer barrel 2, and the outer wall of sleeve 1 is provided with 2 journal stirrups, sleeve 1 and barrel 4
Top is connected, and sleeve 1 is located at the top of outer barrel 2, and one end of buffer 7 to be measured and the journal stirrup of sleeve 1 are connected by screw thread, the other end
It is connected with buffer mounting stand 5.
The bottom plate of the buffer mounting stand 5 is mounting surface, and mounting surface band is cambered, coordinates buffer to install with outer barrel 2
Seat 5 is provided with journal stirrup, and journal stirrup is provided with through hole, is connected with one end of buffer 7 to be measured.Provided with reinforcement between journal stirrup and bottom plate
Muscle.Respectively there is an exhausting hole bottom plate both sides, are connected with outer barrel 2.
The connecting interface of buffer 7 to be measured, one end is sleeve, and one end is buffer mounting stand, and two ends are connected using screw thread
Connect.
