Shock tunnel model suspension test device and method

The invention relates to the technical field of wind tunnel tests, in particular to a shock tunnel model suspension test device and method. A plurality of suspension points are arranged in a model, a line breaking mechanism is arranged at each suspension point, a plurality of suspension lines are connected with the corresponding suspension points respectively according to preset posture requirements, a model system is suspended at the axis position of a spray pipe in a preset posture before a test, and after a shock tunnel breaks a membrane, generated shock waves are spread to the downstream of a low-pressure section of the wind tunnel; a pressure sensor near a membrane cavity is scanned, a release signal is triggered, a receiver installed in the model receives the release signal, and a resistance wire is instantaneously heated to a red hot state through a large current generated by instantaneous discharge of a capacitor, so that a suspension wire is fused, and model release is realized. When airflow enters a
