“…Finite element software was used to simulate the deformation of the die assembly, and strength and stiffness functions were established to optimize the topology of the rib plate and the thickness of the die surface. The main optimization methods include fuzzy Taguchi method [27] and response surface method [28]. Lin and Kuo [29] used the fuzzy-based Taguchi method to optimize the internal structure of the drawing die, increase the deflection of the drawing die and reduce its weight.…”

The stamping process analysis and layout of automotive panels are extremely complex and time-consuming, which directly affects the quality and cycle of product development. Based on the CAGD theory of complex curves and surfaces, process design knowledge, and multidisciplinary optimization techniques, an intelligent automatic process analysis and layout system has been developed. The process feature analysis method based on discretization and merging idea has been proposed to accurately and automatically identify process features such as piercing, trimming, flanging and restricting. The process feature dispersion method based on curvature and normal variation of the forming surface is proposed to ensure the accuracy of feature dispersion. The combinatorial optimization algorithm is proposed to merge the discrete features according to the stamping direction and the geometric parameters of the features to reduce the number of process steps as much as possible. Moreover, a process constraint diagram with combined features is constructed, which is used as the initial solution and sequence constraint conditions for the process layout to effectively ensure the rationality of the process layout. Based on the die design rules, the simplified tools of the process features are created, and the rapid interference detection algorithm of the tools is proposed to realize the automatic layout and optimization of the stamping process. Finally, the aforementioned algorithms are seamlessly integrated into the NX software to develop an automatic analysis and layout system for the automotive panel stamping process. The feasibility, accuracy and efficiency of the system have been demonstrated through the example of the wing panel and the system has been successfully applied in enterprises.

The impacted buckling problems of the slender composite column have a particular essential engineering meaning for the civil engineering, mechanical engineering, and nuclear power engineering fields. Specifically, the contact duration time and buckling time are of importance to design nuclear reactor. This paper mainly concentrates on the dynamic buckling of a slender composite column subjected to a sudden axial load in a hygrothermal environment. In this study, the distribution of strain of the column is considered nonuniform. The humid and thermal factors are taken into account in the stress–strain relation. Employing the composite material's constitutive relation, the buckling governing equation of the composite column can be obtained. The Galerkin method and Laplace transform are applied to solve the buckling problem of the composite column. In this process, the contact duration time and the buckling time are two significant parameters that are typically considered in this research. In the numerical section, the present solutions are validated by comparing to the result in published research. The effects of the kinetic energy of the impactor, geometrical features of the column, and hygrothermal factors on the buckling solutions are studied as well.

“…However, in some cases, the pressure distribution of the die face is ignored by the designer. 1 This design thus leads to the increase in the size and weight of the stamping die which results in excessive costs as well as difficulties in transportation and installation. 2 On the other hand, design of a die with fewer structural ribs can save the cost of material and energy consumption in operation and transportation but may have the problem of die failure.…”

Today, die design standards are used to design the structure of die components. These standards are usually based on high safety factors. So, the die components are often heavier and larger than required. In this article, a software package is developed which can design an appropriate topology of body structure of stamping die components with a reduced weight. This is done by implementing the evolutionary structural optimization algorithm. The proposed structure can also be modified by the designer to accommodate for a simpler casting method. This software package is developed in Microsoft Visual C# programming environment with a link to Abaqus software to analyze the finite element simulation of the process. The operation of the software is demonstrated by an example where the die for a sheet metal part is studied. The die components are initially designed, analyzed and compared with the standard die (the die which is in general use today). The final results show a reduction of 37% of volume and 8% of maximum displacement, respectively.
