文摘
- •
Suppress periodic noise and perform real-system-resembled AVC simulation are demands.
- •
A stepped-up multiple-source multiple-harmonic AVC algorithm is proposed.
- •
An accelerated finite element model in-loop simulation (FEMILS) scheme is proposed.
- •
Numerical studies on a variable section cylindrical structure is conducted.
- •
Algorithm convergence is improved and FEMILS is verified to be valid and effective.
