The paper proposes an optimisation strategy for the design of structures made of three-dimensional woven composites. The knowledge of the weaving architecture is essential to properly optimise the design of the structural components subjected to specific load conditions. Owing to the hierarchy and periodicity of the textile composite materials, a multi-scale parameterisation modelling strategy combining the adoption of a representative volume element and periodic boundary conditions is employed to estimate the behaviour of stiffened panels. In order to minimise the expensive computational cost, response surface method techniques are used to generate the approximated structural responses in an efficient and applicable way. The approach here proposed consists of a multi-scale parameterization analysis strategy and an optimisation framework based on the response surface technique and genetic algorithms. The optimal design results are verified by finite element analysis proving that the response surface method integrated with genetic algorithms allows to easily investigate the influence of the fabrics constitutive parameters on the structural behaviour. © 2016, Deutsches Zentrum für Luft- und Raumfahrt e.V.

In this paper, space manipulator man machine cooperation system structure and operation mode of Mir Space Station and International Space Station are reviewed briefly. Based on this, system structure, control mode, operation mode of Chinese first space manipulator and dexterous hand man machine cooperation experiment are introduced. Mathematics models and ground tests methodology of man machine cooperation are given. Via on orbit experiment, flight scheme and ground validation of space manipulator and dexterous hand man machine cooperation are reasonable. Through Chinese first on orbit space manipulator and dexterous hand man machine cooperation technology experiments, not only the technology foundation of man machine cooperation is established, but also it is accumulated experience for Chinese space robot. © Springer International Publishing AG 2017.
