Description

technical field [0001] The invention relates to a test device, in particular to a tension-compression-torsion coupling loading test device for checking the structure of an inflatable tube. Background technique [0002] The inflatable tube structure is one of the most commonly used load-bearing structures in the inflatable deployment structure. The key to its application is that the inflatable tube structure must have a certain longitudinal tensile or compressive capacity, as well as a circumferential torsional capacity. The so-called longitudinal tensile / compression capacity refers to its ability to resist deformation when the inflatable tube is subjected to tensile / compressive loads; while the hoop torsional capacity refers to its ability to resist deformation when the inflatable tube is subjected to torsional loads. Ability to resist torsional deformation. The smaller the deformation of the inflatable tube, the stronger the bearing capacity of the inflatable tube. Inflat...
