異型管孔型設(shè)計(jì)的CAD組裝法

CAD Assembly Method for Design of Shaped Tube Pass

摘要: 借鑒活動(dòng)板房設(shè)計(jì)、制造和組裝的工藝流程,借助Auto CAD平臺(tái),從“圓形→異形”孔型變形曲線參數(shù)的設(shè)計(jì)、獨(dú)立變形曲線的“制造”(畫(huà))和獨(dú)立變形曲線的“組裝”3個(gè)方面,介紹了異型管孔型的CAD組裝法。提出充分利用CAD原則、逆向思維變形孔型原則、公稱尺寸原則和流程化原則等。該方法省去了異型管孔型設(shè)計(jì)過(guò)程中的繁瑣計(jì)算,使異型管變形合理,提高了孔型設(shè)計(jì)效率。

Abstract: Borrowing the process flow of design, fabrication and assembly of the prefab house, and using the Auto CAD platform, the CAD assembly method for shaped tube pass is elaborated, focusing on the three main aspects, i.e., design of deformation curve parameters of the“ round-shaped” pass, “fabrication” (drawing) of the independent deformation curve and“assembly”thereof. It is proposed to take full advantage of the CAD principle, the adverse thinking deformation pass principle, the nominal dimension principle and the streamlining principle. Thanks to the said CAD assembly method, the miscellaneous calculation steps normally asked for design of shaped tube pass is left out so as to obtain reasonable deformation of the shaped tube, and also get the design efficiency enhanced.
