摘要
In this paper, we investigate the influence of explosive parameters on the results of Sobol variance-based sensitivity analysis in the context of underwater explosion simulations. While there is an extensive body of literature related to this field, none of the existing studies has specifically examined the effect of explosive parameters on the results and conducted Sobol variance-based sensitivity analyses. Our findings demonstrate that the "K" and "k" explosive parameters are the most impactful, and both explosive parameters and mesh structures considerably affect the simulation outcomes. These insights can be employed to enhance the accuracy of numerical simulations of explosive-target interactions. We begin by introducing the acoustic-solid coupling (ASC) numerical method and the Sobol variance-based sensitivity analysis technique. We then delve into the explosive parameters and mesh structures utilized in our study. Finally, we present the outcomes of our sensitivity analysis and discuss the implications of our findings in light of the existing literature. The insights derived from our study can contribute to improving the accuracy of numerical simulations of explosive-target interactions. By comprehending the effects of explosive parameters and mesh structures, we can refine our simulations and reduce the uncertainty associated with the results, ultimately advancing the field of underwater explosion analysis and filling the identified gap in the literature.
