    本文以雙橫臂獨立懸架的轉向傳動機構作為研究對象，選擇對斷開點和節臂球銷的位置進行優化設計，在此基礎上建立了基於多體系統動力學的導向機構和轉向傳動機構的數學模型，運用該學科的運動學分析方法研究機構的運動規律，編制了通用優化設計軟體。由於考慮了更多的空間因素，取消許多影響準確性的假設，因此建立的數學模型與傳統的方法相比更能反映實際運動規律，得到的優化結果也更加精確實用。此外，本文還針對導向機構進行受力分析，在建立該機構的空間動力學模型后，運用多體動力學中的動力學分析方法研究各個桿件的受力，計算出上下球鉸的約束反力，並開發出了相應的通用計算程序。

  4. There are many plants that have the character of time - varying, large delay, large inertia in the process of production of modern power station such as the superheated steam temperature, the reheated steam temperature, the water treatment of boiler and the load regulation. some of them have the strong character of nonlinear and some of them are multivariable coupling systems it is very difficult to obtain good effect of control by conventional pid control. it is necessary to set up the mathematics models of controlled plants if applying control means of modern control theory such as self - adaptive control, optimal control decoupling control and predictive control. and these control systems have large calculation and bad character of real time in general. these disadvantages make them be not able to meet the need of real production process and limit the application of them in modern power station. now the generator units are developing towards large capacity and high parameters. many new kinds of generating electricity means are coming into being. the characers of production units of power station become more and more complex but the demand to quality of control becomes more and more strict. the new control means are in bad need to control them effectively

    現代電站的生產過程中存在過熱汽溫、再熱汽溫、鍋爐水處理、負荷調節等許多大遲延、大滯后、特性時變的對象，它們中有些還是具有強非線性特性的對象或多變量耦合系統，採用常規的pid控制手段很難取得良好的控制效果。若應用現代控制理論中的自適應控制、最優控制、解耦控制、預測控制等控制手段，則需要建立被控對象的數學模型，而且往往控制系統的計算量大、實時性差。這些缺點使其很難滿足實際生產過程的需要從而極大地限制了其在現代電站中的應用。
