解釋
截面厚度-
On the premise of a given set of material parameter, structural boundary shape and condition, design variables - thickness of plate and shell, is designed to minimize the structural weight subjected to the constraint conditions. 1. for the problem with size and stress constraints, full stress design method is used to solve the sectional optimization of plate and shell structures
在給定了板殼的材料常數、板殼結構的邊界形狀和邊界條件的前提下，確定表徵板殼厚度的設計變量，在滿足約束條件下實現結構重量最小： 1 .對于尺寸和應力約束的問題，使用滿應力方法求解。 -
Reasons : firstly, sectional dimension is so little that torsional stiffness of single - beam is n ' t enough. secondly, protective layer thickness is too thin to protect concrete reinforced bar and reduce durability. lastly, each main beam is joined by cross girder and the more rigid of cross girder the more entirety of bridge
橋梁局部損壞較嚴重，主要原因是主梁截面尺寸過小、肋板過于薄弱，造成單梁抗扭剛度不足；保護層厚度不夠導致鋼筋外露引起銹蝕，降低了橋梁的耐久性；各主梁採用橫隔梁連接成整體，橫隔梁的剛度越大，橋梁的整體性越好，但調查結果顯示，實際情況中並不能達到理想的整體剛度。 -

In static test, t - shaped and l - shaped specimens were respectively divided into four groups according to concrete strength grades, sectional height to thickness ratio, reinforcement ratio and ratio of axial compressive force to axial compressive ultimate capacity of section. how these factors affect the load - carrying and deformation of short - leg shear wall is known by analysis the result
在擬靜力試驗中對t形和l形短肢剪力墻分別進行了四組試驗，通過對試驗結果的分析，揭示了混凝土等級、截面配筋率、軸壓比和墻肢截面高厚比等因素對短肢剪力墻承載力和變形的影響。 -
Based on the ansys finite element method software, structure of the new type elliptical cam is researched, effect of the flexible - hinged structure ’ s cross - sectional thickness and the magnitude of pre - tightening force to the performance of elliptical cam is analyzed, using the analysis result, flexible - hinge structure of the elliptical cam is designed in reason
用ansys軟體對新型橢圓凸輪進行了結構有限元分析，分析了柔性鉸鏈最小截面厚度和預緊力的大小對橢圓凸輪性能的影響，根據有限元分析結果，合理設計了橢圓凸輪的柔性鉸鏈結構。 -
The work of this thesis lays a solid foundation for the integration of cad, capp and rp. the main work may be summ arized as follows : ( 1 ) after discussing all kinds of existing algorithms, this thesis presents a new kind of adaptive slicing algorithm that determines the slicing thickness by comprehensively considering the surface normal and the cross - sectional area. and for the same part, a comparison between the adaptive slicing and the equal - thickness slicing methods is performed
論文所做的主要工作如下： （ 1 ）在綜合考慮各種分層演算法的基礎上，提出了法線與面積綜合判定法來確定分層厚度的cad模型直接自適應分層演算法：並針對同一模型對自適應分層和等厚分層進行了比較，結果發現：自適應分層在精度方面雖然與等厚分層基本相當，但是其層數可以顯著減少，所以採用自適應分層可使成形效率顯著提高。
