Embodiment Construction

[0031] like figure 1 As shown, it is a schematic structural view of a multiaxial tensile testing machine 10 of a preferred embodiment of the present invention, figure 2 for figure 1 A side view of the multiaxial tensile testing machine 10 shown in .

[0032] The multi-axis tensile testing machine 10 includes: a mounting table 110, a support portion 120, a storage plate 130, several fixed pulleys 140, a laser extensometer 150, a lifting mechanism 200, a force sensor 160, several clamping parts 300 and several steel rods. Cable 170.

[0033] The support part 120 is fixed on the installation platform 110, and the storage board 130 is fixed on the support part 120. In the present embodiment, the support part 120 is a rod-shaped structure, and there are multiple support parts 120. In this way, the storage board 130 is fixed on multiple supports. On the part 120, prevent the storage board 130 from tilting due to excessive force on the storage board 130, so as to increase the sta...

Abstract

The invention relates to a muitlaxial tension test machine, which includes a mounting bench, a supporting part arranged thereon, an object board arranged on the supporting part, a plurality of fixed pulleys which are disposed uniformly and are arranged on the object board, a laser extensometer arranged on the mounting bench towards the object board, a connecting board fixedly connected to the mounting bench, a motor and a ball screw rod member arranged on the connecting board, a moving disk arranged on a force sensor, and a lifting mechanism which passes through the mounting bench and is fixedly connected to a screw rod in the ball screw rod member, a force sensor, a plurality of holding members arranged uniformly on the object board and steel ropes. The motor drives a nut in the ball screw rod member to rotate. The screw rod is fixedly connected to force sensor. The steel ropes are winded on the fixed pulleys and is connected to the moving disk and the holding members. The screw rod is driven by the motor to be reduced and applies a down-drawing force on the moving disk through the force sensor, so that the holding members are pulled correspondingly through the steel ropes, thereby achieving stable tension in multiple directions on a thin material. Because the moving disk applies tension on the holding members at the same time, force uniformity on thin material is ensured.

Description

technical field [0001] The invention relates to the field of tensile performance testing of thin materials, in particular to a multiaxial tensile testing machine. Background technique [0002] Tensile tests can measure important mechanical properties such as elasticity, strength, ductility, strain hardening and toughness of materials. In engineering applications, tensile properties are one of the main bases for the static strength design of material structures, which can reflect the fatigue resistance and fracture properties of materials. [0003] In the prior art, a tension meter is used to stretch the thin material in a single direction in the tensile performance test of the thin material, so that the test data cannot fully reflect the mechanical performance index of the thin material. In addition, due to the unstable pulling process, the thin material is not uniformly stressed and the direction of the force cannot be kept consistent, resulting in inaccurate test data. ...
