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.
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.
