and the relationship between forming result and parameters is established by using regression analysis, based on which the forming parameter for the process can be determined rapidly and exactly by FEM.
Furthermore, this essay is to describe simulation and research on various material parameters of barrel type parts deep drawing and square deep drawingimpacted by numerical simulation technology, it shows that various material forming parameter will have a certain impact on deep drawing against the blind pursuit of high data of material forming feature parameters in practice.
Depending on the conventional experiences or stamping again and again to seek the best forming parameter and mould structure, on the one hand the product quality can not be ensured, on the other hand the prime cost can not be decreased, which will become the choke point when new car come into the market.
Marc,a nonlinear software of finite element method,and genetic algorithm of optimization,a program of optimization for the forming parameters of mechanical expanding process is developed in Python by means of the development of MSC.
Forming parameters such as mat thickness, and pressing parameters such as press closing rate, were accounted for in a combined viscoelastic model with creep.
Multi-objective optimization of forming parameters for tube hydroforming process based on the Taguchi method
The purpose of this study is to develop a method to analyze the effects of the forming parameters on the quality of part formability and determine the optimal combination of the forming parameters for the process.
The effects of the forming parameters on the tube hydroforming process are studied by finite element analysis and the Taguchi method.
In this work, a free bulging tube hydroforming process is employed to find the optimal forming parameters combination for the highest bulge ratio and the lowest thinning ratio.
Soot formation parameter and polyatomic carbon complexes
The second part is aimed at finding a soot formation parameter and considers the mechanism of forming polyatomic hydrocarbon complexes that determine the concentration and the sizes of soot particles in a natural gas flame.
The combined effect of fluoride and phenytoin on each serum and bone formation parameter appeared to be less than additive.
Also non-time separability in the utility function with habit formation parameter around 0.9 is strongly supported by the data.
For time non-separable preferences, the small-sample distributions are strongly influenced by the habit formation parameter.
This article gives a preliminary opproach to the technology parameter for pressing bend shaping of large cured waveguidest waveguides (overe10cm) analyses its results and there fore shows the main factors causing diffisulties inthe shaping so that correspording remedies can be taken to obtain ideal effects at the first test.
The mechanical properties and deep drawing parameters n and r were measuredfor the annealed 08 Al cold rolled sheet.The measurement results were analyzad by progressiveregression methyl.The anti-aging and anti-cold short properties of the sheet were conducted.Theexistence forms of the added rare earth elements in the steel were also analyzed.
