Abstract

The invention relates to a prestressed coated fabric membrane material bursting test device, which belongs to the technical field of membrane engineering and solves the problem that the membrane material test piece slips in the fixture in the prior art, and the cost of the bursting device is relatively high and most of them are not applicable Technical issues related to coated fabrics. The invention provides a prestressed coating fabric membrane burst test device, including a fixture, a prestressed unit, a computer system, a bracket, a control system, a lead screw, a sensor, a speed control system, a beam, a punch and Data collector; the bracket includes a column and a base, the base is set on the ground, the fixture is set on the base, the column is equipped with a beam and a servo motor, the side of the column is equipped with a screw and a speed control system, and a control system is installed above the beam. The controller is connected with the control system; the punch is fixed on the beam and connected with the controller. The bursting test device provided by the invention is used for testing and researching the mechanical properties of coated fabrics in membrane engineering applications, and provides a reference basis for the bursting damage design of membrane structures.

Description

technical field [0001] The invention relates to the technical field of membrane structure engineering, in particular to a bursting test device for coated fabric membrane material with added prestress. Background technique [0002] In practical engineering applications, the membrane structure is made of a variety of high-strength thin film materials and reinforcing components in a certain way to generate a certain pre-tensioned stress inside to form a certain spatial shape. The membrane structure is pre-stressed in advance and stretched at the boundary. Make the membrane surface in a certain prestressed state to ensure that it can withstand a certain external load. [0003] The membrane structure is exposed to the outside world for a long time, and it is inevitably subjected to various loads, which will cause certain deformation or defects in the membrane material. Partial damage or even overall damage. Therefore, it is necessary to simulate the use and damage process of th...
