摘要

为了提高轮缘驱动推进器(RDT)的抗压能力和扭矩密度,以应对复杂恶劣的深海环境,提出了一种磁通调制 RDT(FM-RDT)。该推进器采用磁通调制机(FMM)作为驱动机,利用调制环实现深海压力保护,并通过磁场调制效应实现大扭矩驱动。在气隙区和永磁区建立了子域模型,在铁磁区建立了磁导网络(PN)模型。通过将这两个模型与边界磁通相结合,建立了 FM-RDT 全局磁场的非线性混合分析模型(HAM)。HAM 的计算结果与有限元法(FEM)进行了比较,并分析了结构的扭矩和磁饱和性能。此外,还使用计算流体动力学(CFD)方法模拟和分析了 FM-RDT 的开放水域水动力性能。结果表明,FM-RDT 具有更宽的工作范围和调速范围,更适合作为低速重载深海水下航行器的推进器。

Global Magnetic Field Distribution and Open Water Hydrodynamic Performance of a Flux-Modulated Rim-Driven Thruster
In order to improve the compression resistance and torque density of rim-driven thruster (RDT) to cope with complex and harsh deep-sea conditi ons, a flux-modulated RDT (FM-RDT) is proposed. This RDT uses a flux-modulated machine (FMM) as the driving machine, which utilizes a modulation ring to realize pressure protection in the deep sea and realizes the high-torque drive through the magnetic field modulation effect. The subdomain model is established in the air-gap and permanent magnet regions, and the permeance network (PN) model is established in the ferromagnetic regions. The nonlinear hybrid analytical model (HAM) of global magnetic field of FM-RDT is developed by combining the two models with boundary magnetic flux. The calculation results of HAM are compared with the finite element method (FEM), and the torque and magnetic saturation performance of the structure are analyzed. In addition, the open water hydrodynamic performance of FM-RDT is simulated and analyzed by using the computational fluid dynamics (CFD) method. The results show that the FM-RDT has a wider operating range and speed regulation range, and it is more suitable as the thruster for low-speed and heavy-duty deep-sea underwater vehicles.
