Description
Technical field
The invention relates to a kind of proving installation; More specifically, the present invention is about a kind of apparatus for impact testing.
Background technology
Apparatus for impact testing is used in the fiduciary level measuring product; its principle is; via apparatus for impact testing generation rule or irregular impact power; and after determinand (i.e. product) is impacted; just via long cumulative bad impact fatigue, the flaw that may exist or occur in determinand can be measured, with the intraware to determinand, structure; or the protectiveness etc. of external packing is assessed, thus as promoting the foundation of use reliability and product quality.
In existing apparatus for impact testing, after determinand being placed in the platform that apparatus for impact testing has, then through at least one impact assembly be arranged at below platform, shock-testing is carried out to platform and determinand, to measure after impacting, the flaw that may exist or occur in determinand.
This kind utilizes at least one impact assembly from bottom to top to the mode that determinand impacts, though Related Impulse test data can be obtained, but because in the process of impacting, simultaneously the impact power that at least one impact assembly produces acts on platform and determinand, therefore have part of impact force road (or even most impact power) will be absorbed by platform, and be consumed in the start had nothing to do completely with shock-testing.
On the other hand, according to " newton's third law of motion ", when two objects interact, put on the power of the other side each other, its equal and opposite in direction, direction are contrary, thus " newton's third law of motion " also known as be " action-reaction law ".Under this law, when at least one impact assembly from bottom to top carries out shock-testing, its impact power produced platform, also applies back at least one impact assembly by generation one retroaction power.Thus, because platform and at least one impact assembly are all under the jurisdiction of apparatus for impact testing, and there is spatial placement relation each other that be associated, while platform and determinand being produced and impact power by causing at least one impact assembly, because of the retroaction power acting at least one impact assembly that " newton's third law of motion " produces, also can indirectly cause other to impact to platform and determinand, and affect final testing result.
Afore-mentioned is single impact assembly at least one impact assembly, and under comprising the aspect of several ram hammer, especially obviously.
For example, when several ram hammers of aforementioned single impact assembly are two ram hammers (i.e. the first ram hammer and the second ram hammer), when two ram hammers are that the tilt mode of miter angle is impacted platform, and two ram hammers for arrange in mode respect to one another time, if make two ram hammers sequentially produce platform to impact, then after the first ram hammer completes impact, before second ram hammer impacts, just reaction punch power that aforementioned " newton's third law of motion " generate can be there is on the second ram hammer, thus affect the impact power of the second ram hammer to platform, cause the error in measurement.
Other situations that may produce error are, when this first ram hammer complete impact after this second ram hammer impact time, if the mistiming existed middle also cannot make platform involution to initial rest position, then the micro-displacement now existed also can impact measurement.
From the above, known apparatus for impact testing, though can in order to measure after determinand is impacted, the flaw that may exist or occur, but in test process, still there is considerable parameter or instability factor, and can be difficult to reach and control and obtain result accurately accurately.
In addition, aforementioned impact is hammered into shape in impacting the stress produced instantaneously, can excite a natural response of determinand; And when determinand is for the device that is made up of several element or system, aforementioned impact hammers the natural response in impacting stress that moment produces and then can excite further respectively this element into shape.Research finds, the respectively interference of this interelement natural response, is only in fact the maximum root causing each device or system failure.
In other words, known apparatus for impact testing is because cannot accurately control to impact determinand, therefore will the interference measuring aforementioned respectively this interelement natural response be difficult to, to set up the shock response frequency spectrum (SRS of determinand, Shock Response Spectrum), be also difficult to the fiduciary level and the life-span that obtain determinand accurately simultaneously.
In view of this, how to provide a kind of impact test platform, make it can in the process of carrying out shock-testing, the impact of the aforementioned acting force of effective eliminating, reacting force, and make the displacement of platform minimum, with accurate its shock-testing result, be an industry problem demanding prompt solution for this reason.
