A verification method for authenticity of HIL simulation based on a vibro-impact model

In order to study the method to accurately and quantitatively evaluate the authenticity of results of a HIL (hardware-in-the-loop) simulation system for on-orbit docking, a verification model for the HIL simulation system was established with an undamped elastic vibro-impact model. The evaluation parameters describing the authenticity of the HIL simulation results were presented, and their calculation formulas were derived. Then, a verification mechanism for the HIL simulation experimental test was designed. The experimental verification method was presented in detail. The experimental test facility was established, and verification tests were done on horizontal and vertical degrees of freedom for the experimental system. The testing results and the system adjusting process showed that the verification ideas and method of the HIL simulation system for on-orbit docking dynamics is feasible and applicable.
