[Abstract]:The explosive shock wave test technology is an important research content of warhead power evaluation, and is also an important basis for target damage evaluation. When evaluating warhead damage effect, shock wave pressure must be tested effectively. Based on the parasitic effect of explosion field on measuring the parasitic output of shock wave by piezoelectric pressure sensor, the suppression method of parasitic effect of shock wave pressure sensor is studied in this paper. On the basis of analyzing the mechanism of mechanical shock and vibration in explosion field, the vibration dynamic model of shock wave pressure sensor is established. Based on the effect of shock and vibration on shock wave pressure measurement in different environments, the installation assembly of ground reflection pressure sensor and wall reflection pressure measurement sensor are designed, respectively. Through theoretical modeling and numerical simulation, the suppression effect of the assembly is analyzed. By using ANSYS Workbench platform simulation, the restraining effect of installation components under impact load and vibration load is discussed, the type selection of vibration isolation material is completed, the simulation experiment of force hammer beating is carried out, and the performance of mechanical shock suppression of installation components is analyzed. Based on the analysis of the mechanism of thermal shock in the explosion field, a method of coating silicon grease on the sensitive surface of the sensor is proposed. The thickness of the thermal insulation layer with the best inhibition effect is determined by theoretical calculation and thermodynamic simulation. Through hot water impact simulation experiment, the inhibition performance of applying silicone grease was analyzed. Finally, based on the parasitic effect suppression measures adopted, the shock wave pressure test of explosion field is carried out, and the rationality of the suppression measures is discussed through the data processing and analysis of the measured signals. The experimental results show that the sensor assembly designed in this paper, which can suppress shock and vibration, and the heat insulation method used in this paper are effective and have practical application value. It provides an effective method to improve the reliability of shock wave pressure test results of warhead.
