| 摘 要： | 为满足军用飞机近场噪声的控制和防护需求,对飞机噪声的传播和分布特性进行研究. 建立了某型军用飞机的ANSYS边界元模型,用声学有限元-边界元仿真软件SYSNOISE进行了噪声仿真,获得了飞机噪声在地面附近的辐射结果. 设计了一种可用于机场无人监测的专用无线噪声测试系统. 试验结果表明,该系统可以有效获得飞机的噪声数据,测试结果与仿真结果比较吻合.

| Abstract: | Based on the demand for noise control and protection,a study on the noise diffuse and intensity of military aircraft is carried out.A boundary element model is established,making use of the ANSYS.In the noise simulation SYSNOISE is applied to get estimable simulation results of aircraft noise close to ground.A minitype wireless noise measure system is designed to act as an automonitor,which has been proved to be a practical device. |
