  1. In addition, it was the sign of the initial amplitude growth rate, not the manner of the interface motion that determined whether the amplitude could increase. at weakly nonlinear stage, mode - coupling equations were derived in cylindrical and spherical geometries. it showed that the nonlinear terms were inversely proportional to the position of the interface in cylindrical and spherical geometries

    在弱線性階段,推導了柱和球幾何中模耦合方程,結果表明:線性作用項反比于界面的位置,界面的位置越小,線性作用越強,反之越弱;同時柱幾何中模耦合方程的解表明,在收縮幾何中,擾動在界面兩側的發展是不對稱的,在弱線性階段,不性向內發展的部分受到慣性力的,而向外發展的部分受到慣性力的拉伸。
  2. The paper studied controlling rotor vibration with the super - elasticity of sma and sfd, set up the new equation of sys tern vibration according to the stress - strain curve of sma in super - elasticity state, used the nonlinear theory and the dynamic stability theory to study the vibration of rotor controlled by sma, discussed the stability condition of the system, obtained the relationship of system parameters when bifurcation was appeared, supposed a method that improves the stability of rotor system and restrains vibration amplitude though changing parameters, and finally validated the effect of restraining vibration of the improved system through emulation

    摘要研究利用形狀記憶合金的超彈性和油膜阻尼器控制轉子振動,利用形狀記憶合金在超彈性狀態下的應力應變曲線,建立了新的系統振動方程,運用線性理論和運動性理論研究轉子在形狀記憶合金控制下的振動狀態,討論了系統的性條件,獲得系統發生分岔時系統參數之間的關系;並提出了通過改變參數來提高系統性和抑制振幅的方法,最後通過模擬驗證了改進后的系統振動抑制效果。
