摘要
船(或浮标)上的风杯风速传感器测量风速时，由于船体（或浮标体)的结构问题或风浪的作用，风杯转轴有时倾斜或随浪摆动起伏。由此而能引起多大的测风误差，应进行探讨。因为这关系到对海上测风数据的正确分析和对船(或浮标)上测风仪器工作质量的正确估价。
According to the tunnel test of the cup wind-speed sensor, it is found that the errors of measuring wind are small and negligible when the tilt angle of rotation axis on the sensor is equal to or smaller than 15° and when the axis sways within 15°.On the other hand, it can be observed that the errors will increase with the increase of wind wave when the sensor moves with wind wave in wave tank; the errors become larger then the demand.
