A comparison study was performed on four gear dynamic analysis computer programs under NASAArmy sponsorship. These programs are GRDYNMULT a multimesh program applicable to a number of epicyclic systems, TELSGE a single mesh program, PGT a multimesh program applicable to a planetary system with three planets, and DANST a single mesh program. The capabilities and features, input and output options, and technical aspects of the programs were reviewed and compared. Results are presented in a concise tabular form. Parametric studies of the program models were performed to investigate the predicted results of the programs as input parameters such as speed, torque, and mesh damping were varied. In general, the program models predicted similar dynamic load and stress levels as operating conditions were varied.
