Abstract

Abstract

In the complex battlefield environment, soldiers will not only face the impact damage of bullets and fragments, but also be subjected to the combined effect of shock wave and bullets caused by explosion. In order to enhance the performance of existing protective gears and better protect the safety of soldiers, a human chest composite protective structure composed of polyurea, Kevlar and foam was designed. Based on the LS-DYNA software platform, a finite element model of the chest composite protective structure is established, and the validity of the model is verified by experimental data drawn from open literature. On this basis, air domain, improvised explosive device and transmissive pressure test platform models are established, and the formation of blast shock wave and fragments and their interaction with the protective structure are simulated by the arbitrary Lagrange-Euler method. The transmittance pressures of different protective structures are compared, while the effects of the arrangement types of protective structures and the thickness on the chest protection are analyzed. The results show that under the action of blast shock wave alone, all three protective structures can effectively reduce the overpressure of blast shock wave; different arrangement types of protective structures have less influence on the anti-blast effect, among which polyurea-Kevlar-foam arrangement structure has better anti-blast effect, and Kevlar-polyurea-foam structure has poor anti-blast effect, and the difference between the two pressure peaks is 2.42%. Under the combined action of blast shock wave and fragments, the peak transmissive pressure of all three protective structures is larger than that of the blast alone; the polyurea-Kevlar-foam arrangement structure has a better protective effect, and the peak transmissive pressure is reduced by 18.49% compared with that of the polyurea-Kevlar-polyurea-foam structure, which has the largest peak transmissive pressure. Appropriate increase in structure thickness can reduce the damage to human chest caused by the combined action of blast shock waves and fragments, but continued increase in thickness has limited gain in protection performance.
