物理参数可控的冲击声的高效、准确合成对于声源识别至关重要。本研究提出了一种基于离散状态空间（DSS）方法和模态扩展方法（MEM）的气缸撞击声合成模型。该模型由物理相互作用的三个过程组成，即赫兹接触过程、瞬态结构响应过程和声辐射过程。首先，构造接触系统的模态扩展DSS方程，得到圆柱体的瞬态结构响应。然后利用改进的离散罗利积分获取气缸的冲击声。最后，通过与现有模型的比较来验证所提出的模型。结果表明，所提出的撞击声合成模型比现有方法更加准确和高效，并且易于推广到其他结构的撞击声合成。
The efficient and accurate synthesis of physical parameter-controllable impact sounds is essential for sound source identification. In this study, an impact sound synthesis model of a cylinder is proposed based on discrete state space (DSS) method and modal extension method (MEM). This model is comprised of the whole three processes of the physical interaction, i.e., the Hertz contact process, the transient structural response process, and the sound radiation process. Firstly, the modal expanded DSS equations of the contact system are constructed and the transient structural response of the cylinder is obtained. Then the impact sound of the cylinder is acquired using improved discrete Raleigh integral. Finally, the proposed model is verified by comparing with existing models. The results show that the proposed impact sound synthesis model is more accurate and efficient than the existing methods and easy to be extended to the impact sound synthesis of other structures.
