Paper Abstract

This work is focused on the analysis of optomechanical mountings based on hexapodal kinematics architecture to obtain efficient supports and proper alignment of an optical device. It has been implemented a parametrized approach considering different conditions of load in terms of operative and survival conditions for the analysis. The project is organized in the following steps:

    Definition of the structure with all the geometrical parameters as input for the code. Any type of initial condition (dimension and shape) can be considered starting from the kinematic chain between each part.

    Definition of all the parameters required for the analysis. All the physical proprieties of the materials are defined in terms of mechanical and thermal behavior.

    Definition of the proper mesh, with the selection of proper elements type, boundary conditions and applied loads.

Thanks to these three steps is possible to obtain practically any layout. Realistic survival and operational requirements of both ground and space based application has driven the analyses done. A comparison between the numerical simulations and a real example has been done to validate the modelling technique. The final result is a validated code with user’s interface, and a parametric analysis of the behavior of the optomechanical mountings based on hexapodal kinematics architecture.
