Adaptive hybrid optimization of hydrodynamic deep drawing with radial pressure process by combination of parametric design and simulated annealing techniques

An adaptive hybrid simulated annealing technique with ANSYS parametric design language is developed to optimize hydrodynamic deep drawing assisted by radial pressure process. This work aims to determine an optimal pressure path by redefinition of simulated annealing parameters and creating an adaptive finite element code using ANSYS parametric design language for any cylindrical, conical, and conical–cylindrical cups. The simulated annealing algorithm is developed adaptively with respect to hydrodynamic deep drawing with radial pressure process to link with ANSYS parametric design language code using a script in MATLAB. Parametric definition of process parameters enables the optimization algorithm to change the finite element model configuration in each iteration. Defective product is detected by definition of two failure criteria based on thinning and wrinkling occurrence during the optimization process. The proposed optimization method is employed in fractional factorial design of experiment to investigate the effective parameters on final product quality. Also, a regression model is derived to predict the final product quality based on the maximum thinning percentage under the optimal pressure path. Reliability of the optimization procedure and regression model is validated by experiments.

Reasonable design of hob tip fillet and calculation of modification coefficients were researched to avoid undercutting in this paper. The undercut gears were generated in the virtual environment based on Pro / E software. Meanwhile, parametric finite element models of undercut gear, ordinary modified gear generated by standard hob and modified gear generated by hob with tip fillet radius increased,were founded by APDL (ANSYS Parametric Design Language).The results show that the minimum modification coefficients chosen to avoid undercutting by traditional modification method may not meet the requirements of contact ratio or addendum thickness.While through reasonable design of hob tip fillet, modification coefficients calculated not only avoid undercutting to improve the tooth bending strength but also meet the requirements of contact ratio ε>1.2 and addendum thickness δ>0.25m (module) .

The traditional ballasted track with wooden sleepers covers today most railway lines constructions, including the tracks of tram and metro or the industrial railway branching. In this work, we present an experimental methodology to validate a numerical model based on finite element method, the model was previously well defined using the ANSYS Parametric Design Language (APDL) and adapted to represent a classical ballasted track. The obtained result of the analysis is expressed as a frequency response of the track and it is compared to the experimental result from measurements made on the metropolitan classical railway track of Barcelona.

Hexagonal grid cylindrical latticed shell structure is proposed, due to honeycomb structure (although the hexagon structure) is the most effective structure on save the building materials. As a result of the shell structure always with numerous bars, the distribution of internal force and the design of bars often rely on many parameters, likes the span of the structure, the rise-span ratio of the structure, the size of mesh etc., the large scaled finite element software ANSYS parametric design language ANSYS Parametric Design Language (APDL) be used to establish the model of hexagonal grid single-layer cylindrical reticulated shell. The optimization design also was done to found whether the model was a feasibility one. The analysis process shows that the parametric design method provides great convenience for the design of the structure.

Rupture Pressure

Forming of flat sheets into shell conical parts is a complex manufacturing process. Hydrodynamic deep drawing process assisted by radial pressure is a new hydroforming technology in which fluid pressure is applied to the peripheral edge of the sheet in addition to the sheet surface. This technique results in higher drawing ratio and dimensional accuracy, better surface quality, and ability of forming more complex geometries. In this research, a new theoretical model is developed to predict the critical rupture pressure in production of cone cups. In this analysis, Barlat–Lian yield criterion is utilized and tensile instability is considered based on the maximum load applied on the sheet. The proposed model is then validated by a series of experiments. The theoretical predictions are in good agreement with the experimental results. The effects of geometrical parameters and material properties on critical rupture pressure are also studied. The critical pressure is increased with increase in the height ratio, strain hardening exponent, and anisotropy. Higher punch nose radius expands the safe zone. It is shown that the critical pressure decreases for drawing ratios higher than 4.
