Customer ServiceNumerical model and parameters A typical deployable solar array system composed of a rigid main-body and two flexible panels is modeled based on the NCF-ANCF to study the effects of multiple imperfect revolute joints and flexible components on its dynamic response. The simulation parameters of the system are listed in Table 1.
The solar panels are deployed by the energy provided by preloaded torsion springs mounted at the interpanel hinges. The yoke and the panels are similarly connected with different spring parameters and deployment angles. As the angle between two panels reaches the deployed state the hinge is locked by a locking mechanism.
So far, various researchers have simulated solar panel deployment and locking operations using various methods. Wallrapp and Wiedemann (2002) simulated three-dimensionally the deployment of a solar array using the multibody program SIMPACK.
At the end of deployment it undergoes locking at the joints at an intended position in order to perform its mission as the power source of a satellite. This locking operation may lead to impulsive forces and moments on the system. This incurs a large vibration in the lightweight flexible solar panels.
Low- and medium-income households have low deployment densities despite solar systems being profitable for high-radiation rates, indicating that the lack of financial capability of covering the upfront cost is likely a major burden of solar deployment.
Figure 17 shows the impact of tracking on the deployment of the solar arrays. The tracking systems that majorly impact vibration on the other parts are mainly clearance on bearings when it is relatively too loose and bearing friction when it is relatively too tight. The servomotor has a speed of 100 rpm (about 10.47 rad/s).
