Optimum design of automobile components using lattice structures for additive manufacturing

Abstract

In today’s world, reducing fuel consumption is one of the most important goals for the automotive industry. For this reason, weight reduction is one of the main topics in this research and for various companies. In this research, topology optimization was conducted on a suspension arm as a means of ensuring balance in automobiles. Subsequently, the model, formed by topology optimization was filled with a lattice structure and re-optimized by size optimization to obtain optimum dimensions for the model. These operations are described as lattice structure optimization. Additive manufacturing (3D printer) is necessary to produce complex models (after topology and lattice structure optimization). A static analysis of the new models was conducted by using the finite element method, and the results were compared with those of the initial design of the model. As a result of the comparison, positive results were obtained, and it was shown that topology optimization and lattice structural optimization could be used in the design of vehicle elements. According to the results obtained from lattice structure optimization, design structure can be formed more reliably than via topology optimization. In addition, both configurations and layouts of the cellular structures have a special effect on the overall performance of the lattice structure.

Strength-based design of a fertilizer spreader chassis using computer aided engineering and experimental validation

“…Optimization is essential for today's industry to develop lightweight construction, improved reliability, and affordable, cost-competitive products. 6,7 Structural optimization has been significantly affected and developed by the development of numerical simulation techniques and optimization algorithms. 8 Structural optimization problems are generally divided into three categories: size, shape, and topology optimization.…”

Robust design of a robot gripper mechanism using new hybrid grasshopper optimization algorithm

“…The most important responsibility expected from industrial enterprises is to design new products that meet government regulations and to produce these products with the closest tolerances to the design targets. Many research efforts have been concluded on a wide range of optimization methods for the designing and manufacturing of products that minimize costs simultaneously while maximizing the quality of the products (Abderazek et al, 2020; Aslan & Yildiz, 2020; Baskar et al, 2004; Baskar et al, 2005; Baykasoglu, 2012; Boothroyd & Rusek, 1976; Champasak et al, 2020; Chen & Chen, 2003; Chen & Tsai, 1996; Demirci & Yildiz, 2019; Ermer, 1971; Eskandar et al, 2012; Ewees et al, 2018; Fan et al, 2018; Formato, 2007; Gandomi et al, 2013; Gopalakrishnan & Al‐Khayyal, 1991; Gu et al, 2001; Güler et al, 2018; Gupta et al, 2001; Hamza et al, 2018; Hati & Rao, 1976; Hellwig & Beyer, 2018; Huang et al, 2015; Iwata et al, 1977; Karaduman et al, 2019; Kaveh & Talatahari, 2010; Khalilpourazari & Khalilpourazary, 2017; Khalilpourazari & Khalilpourazary, 2018; Krishna, 2007; Krishna & Rao, 2006; Kurtuluş et al, 2020; Lambert & Walvekar, 1978; Lee et al, 2011; Lin & Li, 2008; Meng et al, 2020; Osyczka et al, 1999; Özkaya et al, 2020; Panagant et al, 2020; Pawar et al, 2010; Pawar & Rao, 2013; Petropoulos, 1973; Prajapati & Patel, 2019; Raja et al, 2018; Rajendran & Vijayarangan, 2001; Rao et al, 2011; Rao & Pawar, 2010; Saravanan et al, 2002; Savsani & Savsani, 2016…”

Additive manufacturing of biomorphic scaffolds for bone tissue engineering

“…In particular, processing of ceramics, polymers and metals constitutes a new branch of computer-aided BTE [10]. Complex geometries, such as lightweight lattice structures for biomedical applications [13] and even pieces for automotive [14] and aerospace [15,16], were addressed via AM through layer-by-layer fabrication. Although many AM techniques have been reported in the literature [17,18], powder-bed fusion using laser [4,19,20] or electron beam [21,22] is assumed to enable the manufacture of metal biocompatible scaffolds with suitable mechanical properties and accuracy for BTE and orthopaedic implants in general, as reviewed in the literature [23].…”
