Title: Numerical Simulation Research of the Combination of Ice Blasting Based on Shaped Charge Technology
Abstract: Using the blasting scheme based on shaped charge technology,the combination of ice blasting model is set up by ANSYS/LS-DYNA software.Through the numerical analysis,the functional relationship between the peak pressure of shock waves and time is obtained and the peak pressure is almost in line with the theoretical calculation result.The stress distribution of ice under the combination of underwater explosion loads is analyzed,and the process of the underwater explosion is investigated.The results show that the target ice is completely broken and the broken ice is smaller in diameter,which is almost consistent with the experimental results.It would provide a reference for the research and application of underwater ice blasting technology in Yellow River and Heilongjiang River,etc.
