Evaluation of a lattice structure for a motor holder

Abstract

PurposeThe aim of this research paper is to design a motor holder in order to minimize the weight of the motor and to reduce its vibrations causing noise pollution.Design/methodology/approachTo meet the requirements of the purpose the use of cellular lattice structures is ideal. Lattice structures ensure both low mass and high strength. Moreover, their absorption properties are relatively interesting concerning the attenuation of vibrations.FindingsThe result of this paper shows that lattice structure can answer to the need of different fields such as aeronautics in the design of lightweight structures which are strong with a low mass. Indeed, the weight of the final structure of the holder is 0.92 g and its safety factor is 5.1 which met the requirements.Research limitations/implicationsThe limitations of the research paper were the RAM capacity of the computer.Social implicationsTo minimize the weight of the holder in a patroller or a plane is to reduce the consumption of fuel. Moreover one of the reasons of optimizing the vibrations is to reduce noise pollution.Originality/valueThis paper is directed to students, designers who want to know more about the use of lattice structure and more precisely honeycomb sandwich structure.
