To implement the optimal matching of structure parameters, a new idea was proposed to improve the vibration environments of optical satellites. As the random response of a honeycomb panel was far beyond the normal range in a satellite vibration test, adding several enforced ribs on this panel was proposed to reduce the response. The function of the enforced rib in reducing the response of simply supported honeycomb panel was researched. The characteristics of honeycomb panel structure in the optical satellite were introduced, and the random excitation load of the optical satellite and dynamic response of the honeycomb panel under this load were also discussed. According to the entire satellite structure, a method to reduce the honeycomb response by adding H enforced ribs on the panel was proposed. In order to study the function of the enforced rib, the finite element method was used to verify the random vibration of the honeycomb panel model with a size of 1 000 mm1 000 mm30 mm. The analysis results show that the H enforced ribs reduce the response of the honeycomb panel obviously. Finally, the satellite finite element model was improved by the vibration test results and its dynamical analysis and optimization was performed. The analysis results show that the response has reduced to 40%, being an acceptable level, which verifies that the H enforced rib is a good choice to reduce the response of simply supported honeycomb panels on optical satellites. 2016, Science Press.
