Embodiment 1

[0033] Put 2000 grams of PBX explosive simulant into the mixing vessel 1, the material of the mixing vessel 1 is stainless steel, the inner diameter is 110mm, and the height is 150mm. Using three stress sensors, respectively the first sensor 3, the third sensor 5 and the fourth sensor 6, the stress of the test is respectively the impact force of the mixed material on the bottom surface of the mixing container 1, the impact force of the mixed material on the top of the mixing container 1 (equivalent top ) impact force, inertial force inside the mixed material. Each stress is tested under the conditions of accelerations of 10g, 20g, 30g, 40g, 50g, 60g, 70g, and 80g, and the results are as follows figure 2 shown. From figure 2 It can be seen that the impact force of the mixed material on the bottom and top of the mixing container 1 is equal and increases with the acceleration; the inertial force inside the mixed material is consistent with the theoretical value calculated by ...

Embodiment 2

[0035] Put 2000 grams of PBX explosive simulant into the mixing vessel 1, the material of the mixing vessel 1 is stainless steel, the inner diameter is 110mm, and the height is 150mm. Install a thermocouple temperature sensor at the position of the second sensor 4, and test the temperature rise of the mixed material under the conditions of accelerations of 5g, 10g, 20g, 40g, 60g, and 30g, and the obtained data are as follows image 3 shown. From image 3 It can be seen that the temperature rise rate is not significantly affected by the acceleration, but is significantly affected by the mixing stage.

Embodiment 3

[0037] 1000 grams of sodium sulfate are packed into mixing container 1, and mixing container 1 material is plexiglass, and internal diameter is 110mm, and height is 150mm. Use the electrostatic isobaric surface 7 and the electrostatic voltage tester 8 to test the electrostatic voltage. Under the conditions of 10g, 20g, 30g, 50g, and 70g, the electrostatic voltage of the mixed material is tested, and the obtained data is as follows: Figure 4 shown. From Figure 4 It can be seen that the electrostatic voltage reaches a large value at the moment of mixing, and increases slightly as time increases. For the same material, the magnitude of the electrostatic voltage mainly depends on the magnitude of the acceleration, but is not greatly affected by the mixing time.

Abstract

The invention provides an explosive vibration mixing process stimulus testing system. The system comprises a CYLINDRICAL MIXING CONTAINER, a vertical column which is suspended in the mixing container;a first sensor installed on the bottom surface of the mixing container, a second sensor installed on the side surface of the mixing container, a third sensor installed on a vertical column and havinga test surface normal perpendicular to the horizontal plane, a fourth sensor installed on the vertical column and having a test surface normal parallel to the horizontal plane, an electrostatic isobaric surface and an electrostatic voltage tester. The system can provide a force, heat and static stimulation quantity testing system for the explosive vibration mixing process, and provides a basis for safety evaluation of the explosive vibration mixing process; measurement of the temperature, the internal impact force, the inertia force and the internal electrostatic voltage of the wall surface of the mixing container and the mixed material can be realized.

Description

technical field [0001] The invention belongs to the technical field of propellant and explosive parameter testing, and in particular relates to a propellant and explosive vibration mixing process stimulus test system. Background technique [0002] Vibration mixing is a new process of propellant and explosive mixing, but there is still a lack of data support and research on the process safety of its application in the field of propellant and explosive. Due to the natural property of explosives and explosion hazards, the vibration mixing process cannot be popularized and applied in the field of explosives without a breakthrough in safety research. [0003] It has been confirmed in previous studies that the forces (impact force, inertial force, friction force, static pressure, etc.), heat (temperature), and static electricity encountered during the processing of explosives are all risk factors that cause explosives to detonate. Therefore, the test of the force, heat and static...
