The test parameters and the test results are shown in Table 4. Figure 45 and Figure 46 show the force curve and the velocity curve at 0.471Hz in X direction while Figure 47 and Figure 48 show the force curve and the velocity curve at 0.471Hz in Y direction the test parameters. Chang 2010 Fig. 43. Force curve Fig. 44. Velocity curve Fig. 45. Force curve 8. Conclusion The ideas on the simulation hardware interface are presented. The simulation hardware interface is a complex mechtronics system it connects the real-time simulation with the hard wares under test and sets up the HIL simulation system. 31 Hardware-In-the Loop Simulation System Construction for Spacecraft On-orbit Docking Dynamics Ideas Procedural and Validation The ideas of the simulation hardware interface simplified the HIL system design and system building. The design problem of the complex HIL simulation system is simplified as a comparatively simple design problem of simulation hardware interface. Through tuning the dynamic characteristics of the simulation hardware interface the dynamic characteristics of the whole HIL simulation system can be rebuilt. Time s Fig. 46. Velocity curve Time s Fig. 47. Force curve Time s Fig. 48. Velocity curve Based on the ideas on the simulation hardware interface the design procedural of the HIL simulation can be divided into following steps the segmentation of the simulated system the establishing of the mathematic model the design of the simulation hardware interface and the building of the whole system of HIL simulation. The research on the single DOF HIL simulation system for spacecraft on-orbit docking dynamics verified the correction and feasibility of the ideas and procedural of the .
