| 摘 要： | 文章通过实验及其信号处理得到了各轮子的声力传递函数。根据这些测量与分析结论可以定量比较装甲车四种轮子受到同样大小的力激励时,其振动和声辐射通过各传递环节而对车内声场的综合贡献大小。以便在降低装甲车车内噪声时,确定哪种轮子是应该着重考虑采取降噪措施的对象,为装甲车降噪措施的合理化研究提供一定的科学依据。

| Abstract: | The effect of vibration and shock of wheels on the noise inside the hull of armored vehicles was studied.Sound-to-force transfer functions of each wheel were obtained by experiments and signal processing.By these results of measurement and analysis,comprehensive contribution of the vibration and sound radiation of four kinds wheels driven by a same force to the inside sound field through various transfer joints.Accordingly,ideas to reduce the noise inside armored vehicles are proposed. |

| Keywords: | armored vehicle vibration noise diagnosis sound-to-force transfer function coherence function |
