  • State of the Art of Generative Design and Topology Optimization and Potential Research Needs
    NordDesign 2018 August 14 – 17, 2018 Linköping, Sweden State of the art of generative design and topology optimization and potential research needs Evangelos Tyflopoulos1, David Tollnes Flem2, Martin Steinert 3, Anna Olsen 4 1 Department of Mechanical and Industrial Engineering, NTNU [email protected] 2 Department of Mechanical and Industrial Engineering, NTNU [email protected] 3 Department of Mechanical and Industrial Engineering, NTNU [email protected] 4 Department of Mechanical and Industrial Engineering, NTNU [email protected] Abstract Additive manufacturing allows us to build almost anything; traditional CAD however restricts us to known geometries and encourages the re-usage of previously designed objects, resulting in robust but nowhere near optimum designs. Generative design and topology optimization promise to close this chasm by introducing evolutionary algorithms and optimization on various target dimensions. The design is optimized using either 'gradient-based' programming techniques, for example the optimality criteria algorithm and the method of moving asymptotes, or 'non gradient- based' such as genetic algorithms SIMP and BESO. Topology optimization contributes in solving the basic engineering problem by finding the limited used material. The common bottlenecks of this technology, address different aspects of the structural design problem. This paper gives an overview over the current principles and approaches of topology optimization. We argue that the identification of the evolutionary probing of the design boundaries is the key missing element of current technologies. Additionally, we discuss the key limitation, i.e. its sensitivity to the spatial placement of the involved components and the configuration of their supporting structure. A case study of a ski binding, is presented in order to support the theory and tie the academic text to a realistic application of topology optimization.

  • The Role of Multidisciplinary Design Optimization (Mdo) in the Development Process of Complex Engineering Products
    21ST INTERNATIONAL CONFERENCE ON ENGINEERING DESIGN, ICED17 21-25 AUGUST 2017, THE UNIVERSITY OF BRITISH COLUMBIA, VANCOUVER, CANADA THE ROLE OF MULTIDISCIPLINARY DESIGN OPTIMIZATION (MDO) IN THE DEVELOPMENT PROCESS OF COMPLEX ENGINEERING PRODUCTS Papageorgiou, Athanasios; Ölvander, Johan Linköping University, Sweden Abstract The work presented in this paper explores several concepts related to the design of complex engineering products and emphasizes on the effects of considering Multidisciplinary Design Optimization (MDO) in the development process. This paper is by no means a comprehensive literature review, but instead, the aim is to discuss some key points through theory and references to common MDO applications. In this respect, the central topics which are addressed herein are the enhancement of the generic product development process, the road towards a better integration of the organization’s functions, the methods to manage complex system architectures, and finally, the shortcomings of the MDO field. As a link to more tangible industrial applications, Unmanned Aerial Vehicles (UAVs) are chosen as an illustrative example due to their technical complexity as well as the demanding requirements of the corresponding market. Overall, the paper shows that despite the current state-of-the-art limitations, MDO can be a valuable tool within the “traditional” design process that has the potential to enable products of better quality while simultaneously reducing the total development time and effort.

  • Numerical Experience with Two-Point Adaptive Nonlinearity Approximation for Design Optimization
    INTERNATIONAL DESIGN CONFERENCE - DESIGN 2004 Dubrovnik, May 18 - 21, 2004. NUMERICAL EXPERIENCE WITH TWO-POINT ADAPTIVE NONLINEARITY APPROXIMATION FOR DESIGN OPTIMIZATION G. Magazinović Keywords: design optimization, function approximation, TANA-3 1. Introduction During the last decade numerous approximation techniques have taken place for application in optimization. Therefore, function approximation techniques emerge as one of the most important fields of interest. A thorough survey on this topic can be found in [Barthelemy and Haftka 1993]. The main objective of various approximation techniques in design and structural optimization is the reduction of repetitive evaluation of cost and constraint functions. In general, more precise function approximation provides faster convergence and more efficient achievement of optimum design. Consequently, the quality of function approximations emerge as one of the most important issues in the field of design and structural optimization. The main purpose of this paper is to investigate and quantify the accuracy of the Two-Point Adaptive Nonlinearity Approximation, TANA-3 [Xu and Grandhi 1998]. The result could be a valuable tool in comparison with other approximation schemes such as the Generalized Convex Approximation, GCA [Chickermane and Gea 1996], numerically evaluated in [Magazinović 2000]. The outline of the paper is as follows: In Section 2, a brief overview of the Two-Point Adaptive Nonlinearity Approximation algorithm is presented. In Section 3, a description of performed numerical tests is given and finally, in Section 4, numerical results are presented. 2. Two-Point Adaptive Nonlinearity Approximation 2.1 TANA-3 Basics The Two-Point Adaptive Nonlinearity Approximation, TANA-3, is the last and probably the best approximation scheme in a well known series of four function approximations: TANA [Wang and Grandhi 1994], TANA-1 and TANA-2 [Wang and Grandhi 1995], and finally TANA-3 [Xu and Grandhi 1998].

  • Generative Design by Reinforcement Learning: Enhancing the Diversity of Topology Optimization Designs
    Generative Design by Reinforcement Learning: Enhancing the Diversity of Topology Optimization Designs Seowoo Jang Department of Electrical and Computer Engineering Seoul National University [email protected] Soyoung Yoo Department of Mechanical Systems Engineering Sookmyung Women’s University [email protected] Namwoo Kang* Department of Mechanical Systems Engineering Sookmyung Women’s University [email protected] *Corresponding author Abstract Generative design refers to computational design methods that can automatically conduct design exploration under constraints defined by designers. Among many approaches, topology optimization-based generative designs aim to explore diverse topology designs, which cannot be represented by conventional parametric design approaches. Recently, data-driven topology optimization research has started to exploit artificial intelligence, such as deep learning or machine learning, to improve the capability of design exploration. This study proposes a reinforcement learning (RL) based generative design process, with reward functions maximizing the diversity of topology designs. We formulate generative design as a sequential problem of finding optimal design parameter combinations in accordance with a given reference design. Proximal Policy Optimization is used as the learning framework, which is demonstrated in the case study of an automotive wheel design problem. To reduce the heavy computational burden of the wheel topology optimization process required by our RL formulation, we approximate the optimization process with neural networks. With efficient data preprocessing/augmentation and neural architecture, the neural networks achieve a generalized performance and symmetricity-reserving characteristics. We show that RL-based generative design produces a large number of diverse designs within a short inference time by exploiting GPU in a fully automated manner.

  • SIMULATION BASED OPTIMISATION for SYSTEM DESIGN Abstract 1 Modelling and Simulation
    INTERNATIONAL CONFERENCE ON ENGINEERING DESIGN ICED 03 STOCKHOLM, AUGUST 19-21, 2003 SIMULATION BASED OPTIMISATION FOR SYSTEM DESIGN Petter Krus Department of Mechanical Engineering Linköping University, SE-58183 Linköping, Sweden Email: [email protected] Abstract Modelling and simulation is of crucial importance for system design and optimisation. It has now coming to a point where whole systems can be handled. In aeronautics, simulation has been strong in the area of flight dynamics and control. Modelling and simulation of basic aircraft systems such as hydraulic systems also has a long tradition. The rapid increase in computational power has now come to a point where complete modelling and simulation of all the sub systems in an aircraft is possible. There are several levels of design from requirement analysis and system architecture down to detail design. There is a clear danger that systems engineering activities are performed only at the top level of a design. In order to have an impact on the product development process it must permeate all levels of the design in such a way that a holistic view is maintained through all stages of the design. This can be achieved if common system model is used where the interaction with other sub- system and the whole aircraft can be studied, and where the system can be optimised from top level requirements. In this paper it is demonstrated how the actuation system control surfaces can be simulated and optimised, using a flight dynamics model of the aircraft coupled to a model of the actuation system. In this way the system can be optimised for certain flight condition by "test flying” the system.
