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.},
