  1. Fist ly, use mass equivalent method to predigest the original rotor system. secondly, use transfer matrix arithmetic to have finished the relative program to calculate the critical speed of flexible multi - tray rotor bearing system by matlab language. thirdly. finish program the unbalance response using riccati - transfer matrix arithmetic and finity buck arithmetic. fourthly, answer to the high vibration of uncontroled system when cross the critical speed, come out to adopt changing clearance damper bearing to control the viberation

    本文對多柔盤轉子-支承系統的振動現象做了以下初步探索:用質量離散化方法把原轉子系統簡化;採用matlab語言編制了對傳遞矩陣法計算多柔盤轉子-支承系統的臨界轉速;用matlab語言對riccati傳遞矩陣法和有限元法編制了程序計算系統的不平衡響應;並針對其過臨界轉速時振動較大的現象,提出採用變間隙控制油膜剛度和阻尼,從而使原系統的在特定轉速(臨界轉速)的一段范圍內不平衡響應減小;並從被動控制與主動控制兩方面進行數值模擬,取的了較好的控制效果。
  2. The principal conclusions include : ( a ) the composite system is composed of both active - bearing structural members and inactive - bearing ones, being of a character of combination of rigid retaining structures with flexible ones, so its working mechanism will be behaved as sharing loadings, waterproof and impermeability, loading transfer, local reinforcement and pre - reinforcement ; ( b ) the experimental results show that much more subsoil will participate in retaining action, soil stresses of internal slope will be shared uniformly and deflections caused by excavation will be reduced notably because of cooperation of nails and cement - soil mixing pile wall ; and ( c ) the internal forces of facing in vertical model will be a control factor of design and the cross section tensile strength of cement - soil wall will govern strength of the

    主要研究結論有: ( 1 )復合土釘支護的作用機理主要為臨時加固土體以保證局部穩定、有機聯系以共同承擔荷載、改善土體性質起到止水抗滲作用。 ( 2 )試驗結果表明:復合土釘支護能夠充分調動周圍土體共同作用,有效地控制基坑變形;復合土釘支護中止水帷幕的插入深度和強度對控制邊坡變形與失穩有較大作用;復合土釘支護效果明顯優於一般的土釘支護。 ( 3 )面層與邊坡土體共同變形,設計時可按外力作用下的彈性地基梁進行計算。
  3. The dynamics behaviors of the flexible jeffcott rotor system supported by unsteady short dynamic bearing are investigated. based on nonlinear unsteady - state dynamic n - oil film force model described by three functions the local stability of the periodic solutions with the controlling parameters, rotational speed ratio, imbalance amount, damping ratio and viscidity, are predicted by using the floquet multiplier. it is found that the period doubling bifurcation is caused by a certain imbalance amount and the hopf bifurcation is created by the lost stability of the oil - film

    研究了非穩態動載短軸承支撐的jeffcott柔性轉子系統的動力特性,基於可用三個函數表示動態油膜的非穩態非線性油膜力模型,將轉速比、不平衡量、阻尼比、粘度作為控制參數,利用floquet乘子預測周期解的局部穩定性,發現倍周期分叉是由一定量的不平衡引起的,而hopf分叉是由油膜失穩造成的。
  4. The characteristics of the intrinsic frequency distribution of the framed steam turbine - generator set foundation are summarized ; it can been seen that the base plate of the framed foundation does not have much effect on the dynamic response of the foundation, and that the " amplitude method " is better than the " resonance method " among dynamic analysis methods. when designing a framed foundation, as long as the load - bearing capacity and stability is ensured, a flexible pillar is better, the amplitude of vibration can be controlled through adjusting the particle quality in foundation design

    論文最後總結了框架式汽輪發電機組基礎固有頻率的分佈特點;指出框架式基礎底板本身對基礎的動力響應影響不大,認為動力分析方法中振幅法優于共振法;並指出框架式基礎設計時,在滿足承載力和穩定性的前提下,柱子應以柔為佳;設計中可以通過調整質點的質量來達到控制基礎振幅的目的。
  5. Geometric, kinetic, and lifetime analysis of anti - rotation mechanism with thrust ball - bearing is conducted, which is commonly employed in the scroll compressor of automotive air - conditioning system, and its wear during later stage ' s operation is also analysed quantitatively. it is pointed out that, in the case of having radial flexible mechanism, the wear between anti - rotation mechanism and scroll wrap exhibits synchronism and self - compensation. otherwise slight rotation would take place with that mechanism and orbiting scroll, resulting in asymmetric pressure within compression chamber pair and radial leakage

    針對汽車空調渦旋壓縮機中最常見的防自轉機構滾珠防自轉止推軸承,進行了幾何、受力及壽命分析,並對其後期磨損加以定性的理論分析.指出在具有徑向柔性機構的情況下,該防自轉機構和渦旋盤齒的磨損具有同步性和自動補償性.在無徑向柔性機構的情況下,防自轉機構和渦旋盤會產生微自轉,可導致壓縮腔對壓力不對稱和產生徑向泄漏
