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擠壓油膜阻尼器控制轉(zhuǎn)子振動(dòng)，利用形狀記憶合金在超彈性狀態(tài)下的應(yīng)力應(yīng)變曲線，建立了新的系統(tǒng)振動(dòng)方程，運(yùn)用非線性理論和運(yùn)動(dòng)穩(wěn)定性理論研究轉(zhuǎn)子在形狀記憶合金控制下的振動(dòng)狀態(tài)，討論了系統(tǒng)的穩(wěn)定性條件，獲得系統(tǒng)發(fā)生分岔時(shí)系統(tǒng)參數(shù)之間的關(guān)系；并提出了通過改變參數(shù)來(lái)提高系統(tǒng)穩(wěn)定性和抑制振幅的方法，最后通過仿真驗(yàn)證了改進(jìn)后的系統(tǒng)振動(dòng)抑制效果。
