چکیده
In this article, a mathematical model has been developed for calculating the energy-power parameters of drawing process in monolithic dies on straight-line machines, and its adequacy validated experimental wire laboratory automated machine. The program allows us to calculate stress, force, tensile strength yield alloy after drawing, safety factor, power. differs that it evaluate uniformity deformation over section, depending technological zone, namely, semi-angular die, coefficient friction degree deformation. To select which ensure uniform cross-section, nomogram was compiled. equations hardening during nickel NP2 are obtained. calculation (Ni 99.6) ∅1.8 mm from ∅4.94 rod is given. Experimental studies have carried out determine machine with an installed ring strain gauge force. A change by 0.02 when leads increase stress force 20%. improve accuracy model, shown future, would be necessary conduct effect values entered into as constant real values, such coefficient, die half-angle, speed, back tension.

Straight-Line Drawing of Quadrangulations
This article introduces a straight-line drawing algorithm for quadrangulations, in the family of the face-counting algorithms. It outputs in linear time a drawing on a regular W×H grid such that W+H = n − 1 −∆, where n is the number of vertices and ∆ is an explicit combinatorial parameter of the quadrangulation.
متن کاملOn Extending a Partial Straight-Line Drawing
In this paper we investigate the computational complexity of the following problem. Given a planar graph in which some vertices have already been placed in the plane (i.e., a partial embedding), place the remaining vertices to form a planar straight-line drawing of the graph. We show that the above extensibility problem, mentioned in the 2003 paper “Selected Open Problems in Graph Drawing” [1],...
متن کاملTransversal Structures on Triangulations, with Application to Straight-Line Drawing
We define and investigate so-called transversal structures related to triangulations without separating triangles, which are equivalent to the regular edge labelings discovered by Kant and He. We study other properties of transversal structures and show that they give rise to a new straight-line drawing algorithm for triangulations without separating triangles, and more generally for 4-connecte...
