Abstract

The European Robotic Arm is a part of the European contribution to the International Space Station (ISS) and has been developed under ESA contract with Fokker Space as the prime contractor. The integration of the flight model has been completed. In the framework of its structural qualification a modal survey test and a boosted modal survey test wsa performed on the flight model at ESTEC premises using the DLR mobile vibration test facility. The purpose of the modal survey test is to determine the modal parameters of ERA in its launch configuration mounted on the actual fixation mechanism. The main goal of the boosted modal survey test is to qualify the strength of the interface between ERA and launcher. The idea of how to achieve the qualification loads is to use inertia forces stemming from excited eigenmodes using suitable excitation points. Small-banded swept-sine excitation in the neighbourhood of appropriate eigenmodes is used to reduce the number of cycles with high load levels to their requisite minimum.
