In this study, deployment analysis is performed on the articulated hinge and the tape spring hinge, which are devices for deploying the deployable structure in space. The results of the analysis and test results using a deployment test equipment are compared and verified. The spring stiffness of the articulated hinge is optimized by using the response surface method(RSM) to meet the deployment design requirements.
Tape spring hinge, a representative model of flexible hinges, deploy deployable structures using the strain energy generated when they are folded. The tape spring hinge maintains the unfolded state when deployed without a separate stopper and latching mechanism. The torque according to the angle is measured because it maintains the deployed state by using the nonlinearity of the torque according to the angle. In order to verify the deployment analysis results, the analysis model is set up with the equations of motion and the angle and torque values are obtained with time.
To verify the analysis results of the articulated hinge and the tape spring hinge, a development test device is constructed. The articulated hinge is selected as the deployment device and three dummy panels are deployed. Making a zero gravity condition like a space orbit is the most important in the deployment test. For this reason, air bearings and wires are connected to the panels to compensate for gravity and test data is recorded using a motion capture camera. The test data results are compared with the analytical data and verified.
