Technical field
The utility model relates to a kind of dropping shock test unit, is particularly applicable to the fall-down test device that fixed angle repeats the research of falling process mechanical property.
Background technology
Connection with wrapping of piece, from production to use, all through transport, unloading, carrying and pile, especially inevitably will be subject to the percussive action that severe pavement conditions produces, cause goods and materials generation vibration to jolt, roll and fall etc. and damage in transport by road process.Therefore, the anti-seismic performance studying packing case transportation has important practical meaning in engineering.
In the anti-seismic performance research of connection with wrapping of piece, the normal reliability of simple fall-down test method to packaging effect and product that adopt is carried out verifying and evaluates, to ensure the safety of product in transport and environment for use.Conventional method uses Drop tester to be discharged from certain altitude by product, makes it free-falling and ground shock is collided.But cannot ensure to carry out revision test with certain fixed angle in process of the test, the Research on Statistics and Analysis of revision test cannot be completed repeatedly accurately.
In order to study the protecting against shock security in packed and transported process, fall and impact process dynamic behavior by analyzing article, in conjunction with the shock drop test test macro developed, carry out the test of packing case dropping impact property, can be and optimize packing type and appropriate design glissando reference data is provided.
Summary of the invention
Conventional drop machine only can complete simple fall-down test process, cannot ensure the repeatability of repeatedly determining angle falling process, and in order to realize determining the research of angle fall-down test, the utility model provides one and determines angle multi-mode fall-down test device.
It is as follows that the utility model solves the technical scheme that its technical matters adopts:
One determines angle multi-mode packing case dropping shock test unit, it is characterized in that, this device comprises: falling test stand, data acquisition system (DAS) and control system, wherein falling test stand comprises: the base (1) formed by cemented platform, vertically be fixed on a pair vertical slide rail (2) on base (1), connect two vertical slide rail (2) and the crossbeam (3) that can be free to slide thereon, first of the anglec of rotation of crossbeam (3) can be locked and determine angle-differentiated latch mechanism (4), for packing case being fixed on the bracket (5) on crossbeam (3), angle-differentiated latch mechanism (8) is determined and by length adjustment suspension cable for second of the angle that sets the upper relative crossbeam of packing case (3) of bracket (5), upper frame (7), the automatically-unhooked mechanism that magnechuck (6) forms, data acquisition system (DAS) comprises and is arranged in the impact sensor-based system of base and the signal processing system for acquisition and processing signal, control system comprises the control gear of the release of control realization uncoupling rigging and realizes impacting the terminal processing system of Data Analysis Services, and data acquisition system (DAS) is connected with control system signal.
As preferably, described angle mode totally 7 kinds of determining angle multi-mode packing case dropping shock test unit, is respectively: 0 °, ± 30 °, ± 45 ° and ± 60 °.
As preferably, described control system utilizes PC to realize.
As preferably, described control system is connected with the signal of data acquisition system (DAS) and is realized by transmission of wireless signals.
When connection with wrapping of piece contacts with base cemented platform, there is percussive action behavior, and obtain crash characteristics by impact endurance test shock data acquisition system (DAS); In this process of the test, can realize determining angle repeatedly revision test by the angle-differentiated latch mechanism on crossbeam, ensure that the repeated consistance of connection with wrapping of piece fall-down test simulated conditions.
This test unit is compared with existing shock table, this test unit structure is simple, have determine angle-differentiated latch mechanism can realize connection with wrapping of piece determine angle dropping shock test, for the scientific experimentation research of connection with wrapping of piece dropping impact property and mechanical characteristic quantitative analysis provide condition.
Accompanying drawing explanation
Fig. 1 is the front view that the utility model determines the structural representation of angle multi-mode falling test stand
Fig. 2 is the side view that the utility model determines the structural representation of angle multi-mode falling test stand
Embodiment
See front view and the side view of distinguishing the structural representation of the utility model test unit as depicted in figs. 1 and 2.
The utility model provides one and determines angle dropping shock test unit, is applicable to repeatedly to determine angle and falls revision test device, can ensure the consistance of repeatedly fall-down test condition.Concrete operations flow process is as follows:
On the bracket 5 fixing by connection with wrapping of piece, packing case is fixed (determining angle along horizontal Y-axis) on crossbeam 3 by determining angle latch mechanism 8; Then by determining angle latch mechanism 4, crossbeam is fixed along X-axis rotation specified angle; The adjustment that packing case falls angle is completed through above-mentioned twice fixing operation.Crossbeam 3 is moved up along vertical slide rail 2 and to contact with top magnechuck 6 (shock drop test height is by magnechuck suspension cable length adjustment), the release of magnechuck is controlled by not shown control system, by packing case test specimen along the downward freely falling body of vertical slide rail, complete impact with base cemented platform 1; Through not shown dropping shock test data collection system acquisition crash characteristics, and transmit it to control system by repeatedly revision test, complete the research of packing case Experimental Study on Seismic Behavior.
