Abstract

The invention provides an impact testing apparatus, comprising a testing platform, a sample supporting seat, an elevating gear, a measuring device and a control device, wherein the sample supporting seat is arranged on the testing platform; an impact assembly comprises an impact hammerhead which is arranged to be opposite to the sample supporting seat; the elevating gear comprises an elevating rack, an adsorption unit and an elevation driving mechanism; the measuring device comprises a first force transducer, a second force transducer and a displacement sensor; the first force transducer is arranged on the upper end of the impact hammerhead; the second force transducer is arranged on the bottom end of the sample supporting seat; the displacement sensor is mounted on the testing platform; and the control device is electrically connected with the elevation driving mechanism, the first force transducer, the second force transducer and the displacement sensor, separately. The impact testing apparatus can carry out impact tests on metal cellular materials; and the impact testing apparatus is capable of accomplishing other drop-hammer type impact tests by only changing a support clamp and the impact hammerhead and can record related data in testing process.

Description

technical field [0001] The invention relates to the technical field of testing the strength characteristics of solid materials by using mechanical stress, in particular to an impact test equipment. Background technique [0002] Metal honeycomb material is a new lightweight multifunctional material with a large number of connected or disconnected pores inside the matrix. Due to the particularity and diversity of microporous structures, metal honeycomb materials have many excellent physical properties, such as high specific strength and specific stiffness, high damping and shock absorption performance, and can maintain low stress It absorbs a large amount of impact kinetic energy horizontally, and is widely used in aerospace, automotive, energy, chemical and construction industries, especially in various energy absorbing components. Metal honeycomb materials have broad application prospects in many fields such as national economic construction and national defense high techno...
