Abstract
The growth of the automobile industry leveraged the development of the toolmaking branch, although this sector had been producing tools for the most diverse purposes. From the inception of the tooling industry, the understanding of the structural response of the designed tools was very limited, so sizing of all the devices and machines ended up in a rather oversized configuration. Over the years it was noted that the competitiveness of the automotive segment can be evaluated by the performance and quality in the production chain, therefore, optimization techniques are used to increase these parameters and to provide tooling quality improvements for the automotive industry, resulting in cost and time reduction. In order to eliminate, or at least alleviate the oversizing problem, the Topological Optimization (TO) approach emerged, which is the result of improved parametric and shape optimization that performs internal and external boundary changes without violating the design conditions. The present work assesses topological optimization analysis of stamping dies for the automotive industry, aiming at cost reduction and improvements in the construction and production processes. The objective of this study is to perform static analyses of automotive stamping tools, for drawing operation, followed by topological optimization. For this purpose, the commercial software of topological optimization Virtual.Pyxis developed by VirtualCAE will be used, which has integration with the Siemens NX package as a solver to perform the modeling and to obtain the design responses. The process loads used as an input of the optimization simulations were obtained by the assembler that owns the tool, in this case the Fiat Chrysler Automobiles (FCA). The goal is to obtain a significant reduction of material due to an optimized design, simultaneously maintaining the quality in the operation process, considering that the removal of material can affect the stiffness of the part as a whole, making it more flexible, thus inducing problems of accuracy in the final formed product.
