The paper shows the results of a research aimed to re-design a space component and to assess its structural integrity under the operating mechanical loading. To achieve multi-functional requirements, lattice structures were used in some regions of the component. An assessment procedure for static and random fatigue loads was developed. The procedure is applicable to components which have both bulk and lattice sections, and constitutes an important element for a successful diffusion of lattices.

Abstract

The paper shows the results of a research aimed to re-design a space component and to assess its structural integrity under the operating mechanical loading. To achieve multi-functional requirements, lattice structures were used in some regions of the component. An assessment procedure for static and random fatigue loads was developed. The procedure is applicable to components which have both bulk and lattice sections, and constitutes an important element for a successful diffusion of lattices. Experiments were performed on lattice samples and on breadboard samples, to validate the assumption of the assessment procedure. Good correlation was found between predictions and experiments.
