The invention discloses an inflatable expansion test platform for a protective lifesaving air bag, which is used for measuring the inflation pressure, flow and surface stress of the air bag, shooting the form change of the air bag and the like. The test bench is mainly composed of an inflation system, a control system, a data acquisition system, a test system and a safety device. Wherein the inflation system is an independent air source device, and the control system and the inflatable expansion test platform of the protective lifesaving airbag can realize the inflation and deflation processes of the airbag under different inlet pressures and flows, and can measure and store related test data in the inflation and deflation processes of the airbag in real time; the parameters include air bag air inlet pressure, air bag air inlet flow, air bag air inlet temperature, air bag internal pressure, air bag internal temperature, air bag inflation time, appearance change and the like. Through test measurement and result analysis, the mechanical characteristics of airbags of different configurations and different materials in the inflation and unfolding process can be deeply researched, and meanwhile, test support is provided for establishing a real and effective airbag inflation mathematical model.
