Institution National Aerospace Laboratory NLR Date 1989-08-22 Abstract For the simulation of rigid spacecraft manipulator dynamics there exists efficient recursive software. Extension of this software for the simulation of flexible spacecraft-manipulator dynamics would have important advantages. In this paper the method of Equivalent Flexibility Modelling (EFM) is outlined. Each flexible body is re-modelled as a concatenation of rigid bodies, acted upon by fictitious loads In addition to the real loads. To calculate the fictitious loads, some modifications of the software are required. A number of test cases has been analyzed. The errors detected in these test cases are within the realm of computational inaccuracy.
