Topology Optimization of Automotive sheet metal part using Altair Inspire
143-150Megtekintések száma:836In an optimization problem, different candidate solutions are compared with each other, and then the best or optimal solution is obtained which means that solution quality is fundamental. Topology optimization is used at the concept stage of design. It deals with the optimal distribution of material within the structure. Altair Inspire software is the industry's most powerful and easy-to-use Generative Design/Topology Optimization and rapid simulation solution for design engineers. In this paper Topology optimization is applied using Altair inspire to optimize the Sheet metal Angle bracket. Different results are conducted the better and final results are fulfilling the goal of the paper which is minimizing the mass of the sheet metal part by 65.9% part and Maximizing the stiffness with Better Results of Von- Miss Stress Analysis, Displacement, and comparison with different load cases. This can lead to reduced costs, development time, material consumption, and product less weight.

Solid-Lattice Stem Optimization Design for Hip Implants
39-46Megtekintések száma:428The goal of this study is analyzed and design a methodology to reduce stem mass, through topology and lattice optimization of a Ti-6Al-4V hip implant, meeting yield stress requirements. Four optimization cases were studied: Topology optimization (1), Lattice design 100% (2), Lattice design 50% (3), Lattice design 25% (4). Five load cases from a study were applied for each optimization cases: Combined (LC1), standing-up (LC2), standing (LC3), going up stairs (LC4), jogging (LC5). The optimized cases design reduced stem mass approximately by 30% (1), 5% (2) ,8% (3) and 2% (4), compared with the total stem hip Ti-6Al-4V implant.

Optimáló módszerek alkalmazhatósága járműipari gumitermékek tervezésében
358-363Megtekintések száma:154A gumitermékek tervezése során a velük szemben támasztott követelmények teljesítése céljából általánosan használt a méret, az alak vagy a topológia optimálási módszer. A vizsgált termék alakja a legtöbb esetben igen bonyolult, továbbá működése közben érintkezésbe lép egyéb alkatrészekkel is. Jellemzően nagy deformációnak van kitéve, melyre a gumi alapanyag erősen nemlineáris tulajdonságot mutat. Ezen feladat analitikus megoldására nincs lehetőség ezért azt numerikus úton kell keresni, melynek futtatása igen időigényes folyamat. Ebből adódik a kutatásom célja, mely a különböző optimálási eljárások hatékonyságának és számítási költségének összehasonlítása. Jelen dolgozat célja az elérhető optimáló algoritmusok alkalmazási lehetőségeinek felkutatása járműipari gumitermékek alakoptimálására. Ismertetésre kerül több helyettesítő modellen végzett optimum kereső eljárás továbbá számos direkt kereső módszer is.

Application of Topological Methods in the Development of Vehicle Components
67-75Megtekintések száma:106Many areas of the industry are characterized by continuous changes, which define new directions of development in product design. The development of computers and software, the spread of modern production tools and the development of material technology make it possible to expand traditional production technologies with modern processes. Integrated CAD systems have occupied their place in the product design and development process for decades, reforming classical design methods. Popular optimization procedures in integrated CAD systems, such as shape optimization, topological optimization and the new generative design process, provide effective solutions for design engineers in more and more industrial application areas. Experience shows that modern design methods can be used in many areas of industry. The appearance of metal powder printing and additive technology make it possible to test the designed prototypes or even to produce the final products. The following article aims to support the above with the help of a case study.

Generative Design of a Mechanical Pedal
48-58Megtekintések száma:846Nowadays, there are various tools that support the initial stages of design available to use for engineers, the traditional Computer-Aided Design (CAD) has been implemented in the engineering components design and replaced manual drafting. However, with the advances and the rapid technology development, new trends emerged to cope with this evolution, namely, Generative Design, Topology Optimization, and Generative Engineering Design. The method is based on numerical algorithms that generate a variety of design and modelling options based on the criteria and constraints set by the designer to allow further design exploration. Proposed in this paper is an implementation of the generative design of a mechanical pedal with further finite element analysis.

Topology Optimization of Acetabular Cup by Finite Element Simulation
22-34Megtekintések száma:438Hip replacements typically consist of a four-part piece. Our research will focus primarily on the acetabular component. Several different types of materials can be used when creating a hip replacement implant ranging from plastic to titanium. Different materials are used to accommodate for allergic reactions or circumventing potential health risks. Aside from the material, the size of the components plays a factor in terms of durability; a larger diameter head might avoid dislodgement though it could increase wear and tear on the stems through constant friction. A patient’s force applied to the hip replacement is usually measured through a number of physical assessments. Finite element analysis (FEA), a computer-based method of data observation, allows for us to accurately simulate hip forces and their impact on the hip replacements. Through this, it becomes easier to predict and calculate the performance of specific designs. Generative systems can also be used to support performance analysis and optimization through assessing a multitude of cases, many of which apply in real-world scenarios. By applying both systems, we designed and modeled an acetabular cup that when measured decreased the mass from 129 grams initially down to 52 grams, a 60% decrease in total mass. Furthermore, the design we created lessened the trauma on the piece through distributing force across the entirety of the piece rather than specific segments only. This shows an increased durability and life expectancy when compared to usual acetabular cups.
