Abstract
The utility model relates to an adjustable mass block for a cushioning material vibration transitivity test. The adjustable mass block with a non-box structure is designed according to the characteristic that during the work of the mass block, only the upper and lower faces of the mass block are in full-face contact with a cushioning material and the other four faces can not be in contact with the material and do not affect the test, and the adjustable mass block is used for solving the problems that a whole-block mass block adopted in a vibration transitivity test for the cushioning material for packaging is high in manufacture cost and inconvenient in use, and the fastening operation for a box-type adjustable mass block of ASTM (American Society for Testing and Materials) standards is inconvenient. The mass of the adjustable mass block disclosed by the utility model can be adjusted according to the difference of the materials and numbers of mounted mass adjusting blocks, the fastening operation for the mass adjusting blocks is convenient, and a sensor can be mounted at the center of the mass adjusting blocks. The adjustable mass block is applicable to cushion packaging material production enterprises, transport package design units and laboratories of related detection and teaching research institutions.
Description
Technical field
The utility model relates to the material properties test field, relates generally to the padded coaming performance test, specially refers to a kind of padded coaming vibration transitivity and tests adjustable mass.
Background technology
According to GB/T8169-2008 testing package during with the padded coaming vibration transmissibility needs use the mass of different quality, change the natural frequency of vibrational system, the response characteristic that encourages to external world with different vibrational systems under the evaluation effect of vibration.But the principle that has only provided in the standard mass requires: 1) the mass surface is smooth Nogata body structure, and quality can be regulated, and is made by hardwood or metal, is provided with the inner chamber that acceleration transducer is installed in its geometric center position; 2) mass should have the Rigidity and strength that guarantees normal test, should select as far as possible a monoblock, as adopts a plurality of masses then should it is fastening, to avoid between the mass without fixing and produce mutually collision.Padded coaming is carried out the test of vibration transmissibility under the different resonant frequencies, then must make the mass of a plurality of different qualities, if the mass cost of employing made of one piece is higher and the rear quality that completes is difficult to change, use inconvenient again.In ASTM D4168-1995 standard, provided a kind of box structure combination mass-adjustable piece (accompanying drawing 1), but this structure need to be carried out in mass box (1) when quality adjustment plate (4) is fastening with wing nut (3), because the less fastening operation inconvenience of the size of box.
Summary of the invention
High and the awkward deficiency of made of one piece mass cost of manufacture is adopted in test for the cushioning material for packing vibration transmissibility, and the inconvenience of the fastening operation of boxlike mass-adjustable piece in the ASTM standard, according to mass only upper and lower surfaces and padded coaming comprehensive engagement when working, other four faces can not contact with material does not have influential characteristics to test, has designed a kind of adjustable mass of non-box type structure.
The technical scheme that its technical matters that solves the utility model adopts is: padded coaming vibration transitivity is tested adjustable mass and is comprised of a lower quality board (5), four screw rods with holes (6), some quality adjustment pieces (7), four gland nuts (8), the plate of improving quality (9) and four sunk screws (10); Lower quality board (5) welds together with four screw rods with holes (6), then forms the basic framework of mass with the plate of improving quality (9) and sunk screw (10); When changing the quality of adjustable mass, unload sunk screw (10) and the plate of improving quality (9), then the some quality adjustment pieces (7) of packing into as required, with gland nut (8) that it is fastening, cover again the plate of improving quality (9) and fixing with sunk screw (10); Sensor (15) is installed on quality adjustment piece (7) or the lower quality board (5).
The beneficial effects of the utility model are: adjustable mass can be according to the quality of the different adjustment mass of the material of installation quality regulating block and quantity, and the fastening quality regulating block is easy to operate, and can be at quality adjustment piece center sensor installation.
