中文摘要 | 本文分析和實驗測試樑式振動角速儀,由漢米敦原理推導出旋轉尤拉樑之運動方程式,以格林函數求得解析解。利用Routh-HuWitz方法探討系統之穩定性,由而求得振動樑旋轉速度和科氏力作用產生之側向振動振幅的關係,並以金屬樑實驗驗證其在低旋轉速度和側向振動振幅成線性關係。 |
英文摘要 | The dynamics of a vibrating beam angular sensor is analyzed. The lateralvibration due to the Coriolis effect of a flexural vibrating Euler-beam under rotationis considered. The equations of motion of a flexurally vibrating beam are derived,and the analytical solution is obtained via Green's function. Stability criteria aredetermined by the Routh-Hurwitz method. Perturbation technique is used to solvethe forces vibration problem of the rotating beam. Linear relationship between theamplitude of the lateral vibration and low angular velocity is derived and verifiedqualitatively by experiments. The analytical solution shows that the beam gyroscopeis less sensitive to the cross coupling effect of rotations. |
