Abstract

The invention discloses a test system and a method for simulating dynamic behaviors of glass under thermoacoustic coupling, and relates to the technical field of building fire protection, and the testsystem is a multi-system synchronization test system consisting of a thermo-acoustic coupling loading system, a dynamic information monitoring system, a smoke exhausting dust removal system, a gas curtain spraying system, a data storage and transmission system and a wireless control system. The dynamic behaviors of the glass in fire can be simulated by combination of the partial and the whole forreal-time monitoring of data changes of acoustic emission, temperature, stress, deformation and cracks of the glass in the fire, and plasticity deformation and fracture of a temperature field, a stress field, a strain field and a crack tip region of the whole glass in the fire site can be macroscopically and microscopically comprehensive analyzed. The test system is safe in operation, high in efficiency and low in cost, and dynamic information of the glass in a fire scene can be comprehensively efficiently obtained.

Description

technical field [0001] The invention relates to the technical field of building fire protection, in particular to a test system and method for simulating the dynamic behavior of glass under the action of thermoacoustic coupling. Background technique [0002] In modern architecture, glass is widely used. As one of the important components commonly used in architecture, it is applied to doors, windows, ceilings, walls and other parts of buildings. Its own good lighting, practicality and artistry make it the "darling" of architects and owners. [0003] Compared with the wall, glass is also non-combustible, but glass is a brittle material, especially in the fire field, it is very easy to deform, crack or even fall off under the action of thermal load, thus forming new vents and new flame spreading channels. The phenomenon of crashing and flashback is formed, which accelerates the rapid spread of smoke and fire. It causes difficulties in personnel evacuation and firefighters' o...
