Abstract : in order to solve the double parameters enveloped in the geartooth flank generating, the complicated double parameter envelope is simplified to the generating process between work - piece and imaginary crown generating gear by means of mathematical transformation. the equation of the imaginary crown generating surface and the partial derivatives are deduced, so the differential geometric parameters of the generating surface can be obtained. by analyzing the generating motion between the imaginary crown generating gear and the work - piece, all the first to third order geometric parameters of the generated tooth flank at any given point can be calculated
文摘:為了解決直接求解展成法加工中存在的復雜雙參數包絡問題時的困難，提出通過數學變換，將此包絡問題轉化為假想平面產形輪與工件之間的展成問題來進行研究.推導了假想產形面的方程和各階偏導矢，於是可獲得產形面的微分幾何參數.通過分析假想平面產形輪與工件之間的展成運動，即可得到被展成齒面上任意指定點的全部一至三階微分幾何參數 -

In this paper, using large - scale current finite element software, analysising nanbu jialingjiang bridge as engineering example, considering the united action of arcade and of arch with the structure on crown, the author build several 3d finite element models including original bridge, dangerous bridge, all phases of strengthening bridges and strengthened bridge. in order to decide the most unfavorable load case accurately and quickly, using static analysis method this paper draws out the influence surface of bend moment for main section ; base on built models the paper analyzes the internal forces on entirely strengthening process and knows the damaged degree of dangerous bridge and does feasibility studying on its strengthening method ; finally, the paper simply analyzes the unite action of arcade and of arch with the structure on crown
本文利用大型通用有限元軟體，結合南部嘉陵江大橋這一具體的工程實例，考慮連拱及拱與拱上建築的聯合作用，建立了包括原橋、危橋、加固各階段和加固后各狀態在內的空間計算模型；為了準確、快捷的確定最不利荷載工況，利用靜力法繪制了舊橋主拱圈各控制截面的彎矩影響面；對其加固改造全過程進行了靜力分析計算，明確了危橋的病害程度並對其加固方法進行了可行性研究；最後，簡單分析了考慮連拱及拱上建築與否對該橋主拱圈內力的影響。
