Static Structural Analysis of a Reconfigurable Rigid Platform Supported by Elastic Legs

Published

Author(s)

F Rudder

Abstract

This report describes a static structural analysis of a rigid planar platform supported by elastic legs. The platform deformations are computed relative to a specified platform position and orientation. The analysis considers deformation due to static platform loads, non-uniform temperatures of the legs, and manufacturing errors of each leg length. The model was developed as a tool to assist in the interpretation of metrology data and the development of an error budget for the NIST Octahedral Hexapod Milling Machine.
