stiff wing 中文意思是什麼
stiff wing
解釋
固定翼-
At present, the equivalent plate methodology based on global ritz solution technique has been used in the studies of aeroelasticity and aeroelastic optimization of composite wing structures, but it stiff exits space to develop
鑒於此，常常採用連續的等效板模型（ equivalentplatemodel ，簡稱epm ） 。目前，基於全局ritz求解技術的復合材料翼面結構等效板方法已用於氣動彈性的基本研究和優化設計，但還不夠成熟。 -
The rayleigh - ritz method is used to lead to analytical expressions for the stiffness and mass matrices and load vector as well as their sensitivities, which uses the simple polynomials to define assumed displacement functions, geometry and construction of wing structures. excluding some selected terms from the displacement functions or using stiff springs at the specified locations imposes boundary conditions. the accuracy of calculated results is improved by including transverse shear effects and using multiple sets of ritz functions in the analysis
它使用簡單多項式作為ritz基函數、定義翼面的幾何和結構參數，利用rayleigh - ritz方法導出翼面結構的剛度矩陣、質量矩陣和載荷向量及其靈敏度的解析表達式，通過排除位移函數中某些選定的項或在指定點使用約束彈簧施加各種邊界條件，考慮橫向剪切變形和使用多組ritz基函數改進分析的質量，使用等效蒙皮和等效夾芯技術提高計算效率。
