摘要
基于大空间运动下中厚截锥壳的非线性动力方程 ,建立了单轴转动截锥中厚壳的非线性振动方程。利用增量型谐波平衡法 (IHBM法 )对单轴转动截锥中厚壳的横向主谐共振、超谐共振及壳体横向挠度的非线性动力响应进行了分析 ,并分转动角速度Ω1为 0和 1的情况进行了比较。
Based on the nonlinear dynamic equation of medium truncated conical shells in large overall motions, the nonlinear vibration equation of medium truncated conical shells with single axle rotation is set up. By using IHBM method, the resonance of transverse principal harmonic and ultraharmonic and the nonlinear dynamic response of shell's transverse deflection are analyzed. The computed results are compared when the angular velocity Ω 1 equals to 0 and 1 respectively.
