Innovative Solution of Acoustic Field Problems

本课题采用矩量法求解混合边界条件下的声场问题。目前，由于没有一种方法可以同时处理两种边界条件（有限域和无限域），这些问题的求解通常采用有限元法和边界元法相结合的方法。矩量法已被广泛应用于求解电磁场问题的微分和积分形式。该方法简单灵活，非常适合解决航空航天和汽车系统中遇到的复杂声场问题。* * * / /

In this project, the Method of Moments is used to solve the acoustic field problems with mixed boundary conditions. At present, these problems are solved using a combination of finite element method (FEM), and the boundary element method, since no single method can handle both types of boundary conditions (finite and infinite domains). The Method of Moments has been widely used so far for solving both differential and integral formulations of electromagnetic field problems. The simple and flexible nature of the method make it ideally suited for solution of complex acoustic field problems typically encountered in aerospace and automotive systems.*** //
