Based on the ANSYS software platforms, the structural vibration and noise of the special vehicle cab structures have been systematically simulated and studied with test modal technology, the finite element and the boundary element methods in this paper.

• 本文通过ANSYS软件平台，建立了某特种车辆驾驶室结构的三维有限元模型和驾驶室内部振动噪声耦合声场模型，综合运用试验模态技术、有限元法和边界元法，对其内部噪声进行了较为系统的分析研究。
