Dynamics characteristics of SINS damping system in shock environment were analyzed by finite element method, as the deformation of dampers may leads to the accuracy loss of SINS. In addition, the influence of absorber stiffness and damping coefficient on dynamics characteristics were studied. The results indicate that the decoupling of vibrations is significant for the accuracy of SINS. However, considering the almost impossible of completely decoupled vibrations, its necessary to carry out an optimal design of the absorber stiffness and damping coefficient to maintain the accuracy of SINS while meeting the requirement of vibration isolation.

State Of Art

In recent years there has been an increasing tendency to use shakers rather than shock devices, for shock testing. The advantage of using the same transducers and fixtures for both vibration and shock tests, is that not only does this reduce initial equipment costs; it also complements the sophisticated digital control systems currently available and significantly reduces set-up and breakdown time in the laboratory. This paper presents a review of the state of art on testing by simulating a shock environment with shakers.
