Abstract
Space payloads which installed on spacecraft such as satellites and airships are
usually experienced random vibrations and low-frequency sinusoidal vibrations
during launching. In this paper, a space payload cabinet is introduced, and the
damping design is carried out by applying constrained viscoelastic damping layer
to the surfaces of the cabinet to ensure that the space payloads can withstand the
above-mentioned mechanical environmental conditions. A reliable connection
between the space payload cabinet and the shaking table is achieved through the
vibration test fixture. The basic requirements for the function and design of the
vibration test fixture are presented. A method for detecting the dynamic
characteristics of the fixture is proposed. The vibration characteristic of the space
payload cabinet is simulated with the finite element software MSC.Nastran. Then
the vibration test of the cabinet is conducted and the vibration response data is
acquired by using the B&K test system. The test results show that the damping
effect of the space payload cabinet is obvious after applying the viscoelastic
constrained damping layer.
