Example Embodiment

[0019] The present invention will be further described below in conjunction with the examples, but it should not be understood that the scope of the above subject matter of the present invention is limited to the following examples. Without departing from the above-mentioned technical ideas of the present invention, various replacements and changes made according to common technical knowledge and customary means in this field shall be included in the protection scope of the present invention.

[0020] See the attached picture: a composite material indentation experiment system with an indenter stabilizing device in the figure, including a workbench carrying the tested sample (usually a flat metal porous material, fiber-reinforced composite material, etc.), and load loading system. The load loading system is a load shaft located above the workbench, a driving device for controlling the movement of the load shaft, and a load sensor. This embodiment also includes a connecting se...

Abstract

The objective of the invention is to provide an experimental system to eliminate unfavorable influence of offset of an indenter in an apparatus used in a composite indentation experiment in the prior art, i.e., a composite indentation experimental system with an indenter securing device. The system comprises a workbench bearing a to-be-tested sample, a loaded shaft located above the workbench, an actuating device controlling movement of the loaded shaft, a load sensor and a connecting seat cooperatively used with an indenter. During an experiment, the height of the loaded shaft is adjusted at first so as to allow the connecting seat connected with the lower end of the loaded shaft to be a certain distance away from the to-be-tested sample, then the upper end of the indenter is snapped into a T-shaped groove of the connecting seat, so the indenter can be vertically pressed towards the upper end of the to-be-tested sample under the action of the loaded shaft, thereby avoiding offset and slide posing severe influence on the experiment and allowing accurate measurement data to be obtained. Moreover, with the system provided by the invention, manual operation is reduced, and damage of mechanical equipment to experimenters is avoided.

Description

technical field [0001] The invention belongs to the field of research on mechanical properties of materials, and in particular relates to a composite material indentation test device. Background technique [0002] At present, the indentation experiment of composite materials is still being explored, and there is no unified standard experimental device in this field. A common indentation test device includes a platform carrying a test sample (usually a flat metal porous material, a fiber-reinforced composite material, etc.), above which there is a loading shaft capable of exerting a downward force. There is an indenter between the loading shaft and the tested sample. According to the needs of the experiment, the indenter is usually made into various shapes, and its lower end is a conical head, a round head or a flat head, etc., and several indenters are often replaced in one experiment. The upper end of the pressure head is the contact surface with the loading shaft. Durin...
