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.
