With the instruction of the computational multi-body dynamics theory, taking optical measurement application in high-speed camera under underwater explosion tests as the background,the anti-shock and vibration isolation system of the high-speed camera was designed,then the multi-body dynamic model for the system was constructed.The reliability of the modeling process based on the scale model test data was improved.Based on the model,the dynamic characteristics of the system were analyzed under the underwater explosion test condition with the shock factor of 0.4.The results showed that the designed system has a good buffering effect and the system meets the anti-shock requirements of the high-speed camera; the design correctness of the system is validated with tests; the design,modeling and analysis method here can be widely applied in other electronic equipments.
