Device and method for evaluating thermal stimulation response intensity under structural constraint of solid propellant

The invention discloses a device for evaluating thermal stimulation response intensity under structural constraint of a solid propellant, and belongs to the technical field of aerospace power. The invention establishes a set of device and method for evaluating the thermal stimulation response intensity of the solid propellant under the structural constraint according to three indexes of shock wave speed, shock wave pressure and aluminum witness plate dent volume. The device structurally comprises an upper clamp, a lower clamp, a heater shell, a heating rod, a thermocouple, an explosion-proof box, a propellant sample, a constraint shell, an aluminum witness plate, a pressure sensor, heating control equipment, an LED point light source, a parabolic mirror group and a CCD high-speed camera. According to the device, the structural constraint strength of the sample can be changed by using different constraint shells, a thermal response rule is obtained, a clear shock wave structure can be shot, and the device is s
