Abstract

The invention relates to a bursting test device for a coated fabric membrane material added with prestressing force, and belongs to the technical field of membrane engineering. The technical problem that in the prior art, a membrane material test specimen slips in a jip, a bursting device has higher cost and is not suitable for coated fabric are solved. The bursting test device for the coated fabric membrane material added with the prestressing force comprises a jip, a prestressing force adding unit, a computer system, a bracket, a control system, a lead screw, a sensor, a speed regulating system, a beam, a punch and a data collector. The bracket includes a vertical column and a base. The base is arranged on the ground, and the jig is arranged on the base. The vertical column is provided with the beam and a servo motor, and the lead screw and the speed regulating system are arranged on the side of the vertical column. The controller is arranged above the beam, and the controller is connected with the control system. The punch is fixed to the beam and connected with the controller. The bursting test device is used for testing and studying the mechanical properties of coated fabric in the application of membrane engineering, and provides a reference basis for the bursting breaking design of a membrane structure.

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...
