Generating line of involute 漸開線發(fā)生線
The characteristics of dynamic response of points along generating line and circumferential line of the cylindrical shells are analyzed , and the effects of l / r ratio on the dynamic response of the cylindrical shells under line - loading are considered as well 分析了沿母線方向和環(huán)向各點(diǎn)應(yīng)力響應(yīng)的特點(diǎn)以及結(jié)構(gòu)長徑比對(duì)應(yīng)力響應(yīng)的影響,在此基礎(chǔ)上比較了沿環(huán)向呈單余弦分布和雙正弦分布載荷的應(yīng)力響應(yīng)。
By the support of national nature science foundation , some key problems of cvt were investigated , and some useful results were obtained as follows : ( 1 ) the relations between metal - belt misalignment in axial direction and transmission parameters were studied . by designing curved generating line pulley or adjusting the axial displacement of pulley , the degree of misalignment of the metal belt was decreaed 本文在國家自然科學(xué)基金重點(diǎn)項(xiàng)目(編號(hào): 59835160 ) ,國家教委重點(diǎn)項(xiàng)目(教技司( 98 ) 121號(hào)) ,重慶市科委攻關(guān)等項(xiàng)目的資助下,對(duì)cvt傳動(dòng)的若干關(guān)鍵問題進(jìn)行了研究,本文的工作為cvt傳動(dòng)的研究、應(yīng)用和開發(fā)奠定了基礎(chǔ)。
