摘　　要：基于物理模型的膜乐器声音仿真技术是运用声学和力学理论,通过二维振动偏微分方程(2D-PDE)来精确描述乐器的发声,该方法已逐步成为目前乐器仿真、声音合成技术领域内的研究热点。文章分析和证明了一个著名二维振动方程的局限性,利用弹性力学理论提出了新的物理模型,并证明了新模型的合理性。Sound synthesis technique by physical modeling has recently become an important domain of science on digital simulation of acoustics. The physical model for membrane musical instruments is derived by the main vibrating structure of instruments in form of a two-dimensional vibration equation. The limitation of a famous traditional model was discussed by theories and experimentations. As a result, a new physical modeling is supposed and implemented for purposes of sound synthesis.
