摘　　要：结合气垫船模围裙振动试验平台项目,用L abV IEW语言开发了该试验平台的测试系统,并测得某中型气垫船相应船模的升沉、纵摇与横摇的频率响应。利用传递矩阵的形式推导了耐波性计算公式,对该船模相应实船进行理论计算,验证了气垫内空气可压缩性对该类大中型气垫船升沉运动响应的重要性。同时分析了实船计算结果与振动平台试验值之间存在差别的原因。With the development of vibration testing platform project for hovercraft model skirt, the testing system has been developed by using the LabVIEW language, which was used to measure the response frequencies of heave, pitch and roll of a medium sized hovercraft. The seakeeping ability calculation formula has been deduced with transfer matrix. Through theoretical calculation of the fullscale ship corresponding to the model, the importance of the compressability of the air inside air cushion to the heave response of such large and medium size hovercraft. The reason of the difference between fullscale ship calculation result and readout of vibration platform test has also been analyzed.
