Abstract

For the spherical hinge’s connection of a 1D deployable truss, the stiffness of the spherical hinge was investigated based on dynamic model updating.The deployable structure was simplified to be in locked condition, considering the stiffness of the spherical hinge only.First, we established the elaborate FEM of a locked truss unit and calculated the initial stiffness values by carrying out the contact analysis.Then we substituted the initial value with the parameterized model with six-directional stiffness spring elements linearizing the spherical hinges’ connection.Afterward, we carried out the modal tests for this locked truss unit, using these modal parameters to identify the spherical hinge’s stiffness.Finally, we utilized the identified stiffness for the finite element modeling of the deployable structure and verified the identified results by using the multi-layer’s modal parameters.The results show that the stiffness identification method of the spherical hinge based on dynamic model updating presented by this paper is effective.
