Application of Abductive Network and FEM to Predict the Optimal Blank Contour of Elliptic Cylindrical Cup in Deep Drawing
In this paper, the finite element method is employed in conjunction with the abductive network to predict the optimum blank contour of elliptic cylindrical cup with ear-less in deep drawing. The earring behavior of the formed cup is caused primarily by planar anisotropy in the sheet. Different cup heights combined with various aspect ratios of the elliptic cylindrical cup are taken into account...
متن کاملfinite element simulation of process and springback of friction aided deep drawing using tapered blank holder divided into eight segments
in this paper, a novel technique on friction aided deep drawing using tapered blank holder divided into eight segments is proposed to overcome defect of friction aided deep drawing using four segments tapered blank holder technique. a taper blank holder is designed to be of two parts: stationary part with 5 degree taper angle and moving parts divided into eight tapered segments. the main functi...
متن کاملAnalysis of Fukui’s Conical Cup Test
Fukui’s conical cup test is the one of the formability characteristics evaluation for various sheet metals. The formability characteristics such as diametrical ratio, maximum drawing load, depth of cup up to fracture are to be evaluated. This test is related to drawing test. This test can be performed by using parameters such as friction, process parameters and without blank holder. In fukui’s ...
متن کاملA fuzzy logic model to determine the effects of die/blank holder angle and punch radius on drawing ratio in angular deep drawing dies
Deep drawing process is one of the widely used methods in sheet-metal forming. With the deep drawing method, products of various geometrical shapes such as saucepans, tubes, perfume and soft drink cans can be obtained easily. Therefore, the optimization of the deep drawing process is very important for the industry. In conventional deep drawing method, no angle is given to the surfaces of die a...
متن کاملThe Study of Deep Drawing of Brass-steel Laminated Sheet Composite Using Taguchi Method
Deep drawing process is one of the most applicable methods in producing industrial parts. In this process, the initial blank deforms to final product using a rigid punch and die. In this investigation, the effect of deep drawing process parameters of brass/steel laminated sheet composites on required forming force has been investigated. The process simulated using finite element method (FEM) an...
