利用偏航─横倾控制机构测量模型的m_x~β和m_X^(ω_X)系数

To Measure Coefficients m_x~β and m_X^(ω_X)of Model Using Yaw-Rolling Control Mechanism

迄今为止，由试验确定的水下航行体的mβx和mωxx系数离散性大、精度差。本文介绍一个利用偏航横倾控制机构测量这二个系数的新方法。文中给出了一个试验示例。结果表明，由该方法给出的试验值是合理的，具有工程精度。

To date, both scatter and uncertainty on coefficients,m and m of submerged bodies obtained in existed experiments are rather significant. A new method to measure tlie two coefficients using a yaw-rolling control mechanism is proposed in the paper and a experimental example is presented herein. The results show that the experimental data based on the method are reasonable,and available for engineering.
