| 摘 要： | 旋臂水池是开展轴对称体水动力研究的常用试验设备之一，水池模型试验中的尺度效应和支撑方式一直是操纵性能试验研究的难点．在合理选取模型尺度、支杆与模型直径比、模型浸深以及模型速度的基础上，进行了轴对称体2种尺度模型和腹、尾支撑2种方式多工况下的旋转导数试验，并得出了线性和非线性旋转水动力导数．试验结果表明，在不考虑支杆干扰的情况下，模型试验中支撑方式对旋转导数的影响是可以忽略的，尺度效应要针对不同的试验对象分别考虑。

| Abstract: | A rotating arm basin is one of the experimental facilities for hydrodynamic research of an axisymmetric body. However,for maneuverability research,the scale effect and supporting way are difficult points to examine in a model test basin.After designing a scale model and determining the diameter ratio of its strut, water depth and velocity of tests on two different scales and supporting ways for an axisymmetric body were developed. The results show that the influence of the supporting way on dynamic derivatives can be neglected under the condition of neglecting interference effect of the strut. The scale effect has to be respectively considered on a different tested model. |
