High and low temperature multi-axis in-situ tensile testing machine

Abstract

The invention provides a high and low temperature multi-axis in-situ tensile testing machine. The multi-axis in-situ tensile testing machine comprises: a first housing; a first ball screw assembly comprising a first ball screw that is rotatably disposed, and a first nut and a second nut that are non-rotatably disposed; a first clamp assembly comprising a first clamp fixedly coupled to the first nut and a second clamp fixedly coupled to the second nut; a second ball screw assembly comprising a second ball screw that is rotatably disposed, and a third nut and a fourth nut that are non-rotatablydisposed; a second clamp assembly comprising a third clamp fixedly coupled to the third nut and a fourth clamp fixedly coupled to the fourth nut; a heating device mounted in the interior of the firsthousing for heating the space in the first housing; and a cooling device mounted to the first housing for cooling the space in the first housing. According to the high and low temperature multi-axis in-situ tensile testing machine, experimental tests in various temperature environments can be realized.

Description

technical field [0001] The invention relates to a tensile device, in particular to a high-low temperature multi-axis in-situ tensile testing machine. Background technique [0002] In recent years, three-dimensional (3D) microstructures with scales ranging from tens of nanometers to hundreds of micrometers have attracted more and more attention from researchers. The reason is that by forming a three-dimensional microstructure with a specific geometric topology in advanced materials, macroscopic materials can exhibit new properties in terms of sound, light, heat, force, and electricity. This kind of material with extraordinary physical properties that does not exist in natural materials is also called "metamaterial". Due to the huge application prospects of metamaterials in various microsystem technologies, the design and preparation methods of three-dimensional microstructures are becoming increasingly popular in China. other research hotspots. At present, in addition to mo...

Problems solved by technology

[0005] The structure of the hydraulic biaxial tensile testing machine is relatively complex, and its use is limited. However, some of the existing mechanical biaxial tensile testing machines do not have equi-biaxial in-situ tensile properties and the characteristics of high and low temperature loading. Simultaneous loading Low efficiency, thus limiting the application of mechanical biaxial tensile testing machines in the field of 3D assembly
