Abstract

In response to the challenges of overpressure testing on the human torso within a semi-enclosed environment,a novel testing system was proposed.This system took into account the complex propagation characteristics of shock waves in semi-enclosed spaces and was designed with a new type of testing structure that employs an anthropomorphic torso test configuration and a multi-channel data acquisition device.A half finite element model was also established for numerical simulation.During the semi-enclosed environment experiment with 200g of TNT explosive,the overpressure at a distance of 2000mm from the epicenter was measured to range from 145.12kPa to 196.31kPa on the front side,followed by the side with a range of 58.83kPa to 82.55kPa,and the back side was the lowest,ranging from 24.69kPa to 27.31kPa.Comparing the experimental results with the simulation results and empirical formulas,the consistency between the simulation data and the experimental values was found to be good on the front and side.However,on the back side,due to the complexity of the flow field within the semi-enclosed environment,the influence of diffraction and reflection led to an increase in error.Additionally,the empirical formula results varied from the test results due to different experimental conditions during the derivation of the formula,but the consistency on the side was still good.

Key words： explosion shock wave overpressure; semi-closed environment; human torso; measurement; data analysis
