In this work, three algorithms combined with two frequency response<br/> function (FRF) estimation methods are proposed for the purpose of regeneration of field <br/> data for six degrees of freedom vehicle motion simulators. Then the algorithms are <br/> tested and the rates of convergence are investigated through simulations with mathematical<br/> nonlinear models and laboratory experiments. The performances of each algorithm are <br/> evaluated based on the variance calculated from the error between the given field data and <br/> the regenerated data in the frequency domain. Extensive simulation and experimental works <br/> suggest that the algorithm, which uses the inverse FRF estimation method and takes into <br/> account the inherent system nonlinearity. reveals the best and satisfactory performance in <br/> the regeneration of field data for the laboratory vehicle motion simulator.<br/>
