چکیده
Abstract In order to optimize the thermal deformation of satellite antenna, a new type negative expansion metamaterial with re-entrant honeycomb for sandwich structure was designed and optimized. Coefficient (CTE), Poisson’s ratio Young’s modulus were calculated by finite element method (FEM). After sensitivity analysis, five parameters optimized response surface (RSM) multi-island genetic algorithm (MIGA). It is found that antenna shows better mechanical properties its reduced effectively.

متن کاملProcess for design optimization of honeycomb core sandwich panels for blast load mitigation
A general process for optimization of a sandwich panel to minimize the effects of air blast loading is presented here. The panel geometry consists of two metal face plates with a crushable honeycomb or other type of core. Optimization is necessary as there is strong coupling between the several variables and the physics, which makes parametric studies relatively ineffective. Virtual testing is ...
