Description
Technical field
The present invention is on a kind of test device；More specifically, the present invention is on a kind of apparatus for impact testing.
Background technology
Apparatus for impact testing is to be used in the reliability for measuring product, and its principle is, is produced via apparatus for impact testing
Regular or irregular impact power, and to determinand（That is product）After being impacted, it can be rushed via prolonged cumulative bad
Fatigue is hit, to measure the flaw that there may be or occur in determinand, with the intraware to determinand, structure, or outsourcing
Protectiveness of dress etc. is assessed, so as to the foundation as lifting use reliability and product quality.
In existing apparatus for impact testing, after determinand is placed in into a platform possessed by apparatus for impact testing, then thoroughly
At least one impact assembly being arranged at below platform is crossed, shock-testing is carried out to platform and determinand, to measure after impact, in
The flaw that there may be or occur in determinand.
Such a mode from bottom to top impacted using at least one impact assembly to determinand, though phase Jing-Well point Guanchon can be obtained
Hit test data, but because during impact, impact power caused by least one impact assembly be act on simultaneously it is flat
Platform and determinand, therefore have part of impact force road（Even most impact power）It will be absorbed, and be consumed in by platform
The completely irrelevant start with shock-testing.
On the other hand, according to " newton third law of motion ", when two objects interact, put on other side's each other
Power, its is equal in magnitude, in opposite direction, thus " newton third law of motion " be also known as be " action-reaction law ".
Under this law, when at least one impact assembly from bottom to top carries out shock-testing, it is to impacting power caused by platform, also
Reaction power application will be produced and be back to few impact assembly.Consequently, it is possible to because platform is all subordinate to at least one impact assembly
Belong to apparatus for impact testing, and each other there is associated space to set relation, will cause at least one impact assembly to platform with
While determinand produces impact power, because acting on the anti-of at least one impact assembly caused by " newton third law of motion "
Power is acted on, also other impacts can be caused to platform and determinand indirectly, and influences final testing result.
Afore-mentioned, it is single impact assembly to impact assembly at least one, and under the aspect comprising several jump bits, especially
Substantially.
For example, it is two jump bits in several jump bits of foregoing single impact assembly（That is the first jump bit and second
Jump bit）In the case of, when two jump bits are in a manner of tilting 45 degree of angles platform to be impacted, and two jump bits is with those
When this relative mode is set, if making two jump bits sequentially produce impact to platform, after the first jump bit completes impact, the
Before two jump bits are impacted, there will be reaction punch power that foregoing " newton third law of motion " is generated in second
On jump bit, so as to influence impact power of second jump bit to platform, the error on measuring is caused.
There may be the situation of error to be for other, and second jump bit is carried out after first jump bit is completed to impact
During impact, if the time difference existing for centre and platform involution can not be made to initial rest position, then now existing small position
Shifting can also impact to measurement.
From the foregoing, known apparatus for impact testing, though can be used to measure after determinand is subjected to impact, institute may
In the presence of or the flaw that occurs, but in test process, still suffer from considerable parameter or instability factor, and can be difficult to reach essence
True control simultaneously obtains accurately result.
In addition, aforementioned impact hammers the natural response that in stress caused by impact moment, can excite determinand into shape；And work as and treat
When the device or system surveying thing to be made up of several elements, aforementioned impact is hammered into shape can then enter one in stress caused by impact moment
Step excites a natural response of the respectively element.Research finds that respectively the interference of the natural response of the interelement, is substantially only
Cause the maximum root of each device or system failure.
In other words, it is known that apparatus for impact testing because can not accurately control to be impacted to determinand, therefore by difficulty
To measure the interference of the natural response of the foregoing respectively interelement, to establish the shock response frequency spectrum of determinand（SRS, Shock
Response Spectrum）, while also it is difficult to reliability and the life-span for accurately obtaining determinand.
In view of this, how a kind of impact test platform is provided, it is effectively arranged during shock-testing is carried out
Except the influence of foregoing active force, reaction force, and make the displacement of platform minimum, be for this with its accurate shock-testing result
One industry urgent problem to be solved.
The content of the invention
