解釋
加鋪厚度設計-
Another topic of this article is to try to find a proper overlay design method. by using elastic layer system ( els ), finite element method ( fem ), genetic arithmetic ( ga ) back calculation and efficacious thickness method, the paper puts forward four design methods. the results say that the position where the max stress appears is not the only one but varies with the thickness of overlay
根據陜西省高速公路瀝青路面病害以及使用性能的實際情況，提出了代表彎沉值的計算方法以及下臥層模量的反演方法，在此基礎上利用彈性層狀體系理論、有限單元理論、遺傳演算法以及有效厚度法等理論對加鋪層厚度設計方法進行了研究。 -
According to the special shape and operate requirements of the torpedo, the structure and moulding process of the torpedo shell are established, in which the body and overlay block with grooves are moulded by fiber winding, and close moulding respectively with the adhesive by limited stop compression. in the light of the selection of raw material system, composite system with outstanding performance are defined, based on which the mechanical properties are tested., with the overall consideration of structural characters and design demands, the main factors which may have effects on the strength and stability ( including stiffness section dimension, stiffeners space, skin thickness and skin lay angle ) is optimized one by one for the structure design parameters on the base of the fem model of skin, stiffness and layover block by fem. as a result, the prototype with 1 : 1 proportion and its structure and lay optimization design are completed. the moulding technology for polyurethane foam moulding the stiffened shell is obtai ned in terms of the design, manufacture moulding, experimental mould and tooling
