Abstract

The mathematical model for the dynamics of HERA must take into account structural flexibility in the slender manipulator links. For the HERA Simulation Facility Pilot, the model will contain one bending mode in each bending plane, and one torsion mode. The present document describes how this model can be simulated with rigid body simulation software through the introduction of fictitious joints. Limitations and extensions are indicated
