Research on Experimental Validation Procedure of Dynamics Hardware-in-the-Loop Simulation System

In order to accurately and quantitatively evaluate the authenticity of the simulation results of the HIL (Hardware-In-the-Loop) simulation system for on-orbit docking, a validation model for the HIL simulation system for on-orbit docking dynamics was set forth. It is a no-damping vibro-impact model. Base on it, a validation mechanism and an experimental validation procedure were elaborated. The evaluation parameters describing the authenticity of the HIL simulation results were presented, and their calculation formulas were derived. The experimental test facility was established, and verification test was done on the horizontal and vertical motion freedom of the experimental system. The test results and the system tuning process show that the experimental validation procedure of the HIL simulation system for on-orbit docking dynamic is feasible and practical.
