Abstract
In order to evaluate the impact of different warhead shapes on the damage efficiency of semi armour piercing warhead effectively, four common semi armour piercing warhead models are established based on Solidworks, and the deck model is established with reference to the deck data of an aircraft carrier. And then the material setting and grid division are carried out based on Ansys so as to construct the explicit dynamic simulation model. The credibility of the model is verified based on the residual velocity theory after the model being established. Finally, based on the established model, the simulation research on the influence of warhead shape on vertical armour piercing ability is carried out. The results show that under the same velocity, the armour piercing ability of sharp oval and conical warheads are better and their residual velocity are higher.
Highlights
Semi armour piercing warhead is a kind of warhead with certain armour piercing ability and certain explosive power
Countries all over the world have invested a lot of research on the damage effectiveness of semi armour piercing warheads, but most of the researches are focus on the impact to deck damage effect of semi armour piercing warheads considering the materials or the kinetic energy characteristics
In order to effectively evaluate the impact of different warhead shapes on the damage effectiveness of semi armour piercing warhead, this paper carries out the numerical calculation and Simulation of armour piercing effectiveness of four warhead shapes based on ANSYS software
Summary
Semi armour piercing warhead is a kind of warhead with certain armour piercing ability and certain explosive power. It is an important means to attack military targets such as ships and armoured protective bunkers. Countries all over the world have invested a lot of research on the damage effectiveness of semi armour piercing warheads, but most of the researches are focus on the impact to deck damage effect of semi armour piercing warheads considering the materials or the kinetic energy characteristics. There are few studies considering the impact of warhead shape on armour piercing effectiveness. In order to effectively evaluate the impact of different warhead shapes on the damage effectiveness of semi armour piercing warhead, this paper carries out the numerical calculation and Simulation of armour piercing effectiveness of four warhead shapes based on ANSYS software
