| Abstract: |
| Objective To investigate the dynamic response of shear model box in Compound Dynamical Environment. Methods Based on the structure characteristics of multidirectional laminar shear model box, the dynamic model was established considering the slippage of different layers. According to the dynamic simulation on the working status of whole centrifuge model, the spectrum of excited force was obtained. Then the dynamic response of shear model box was investigated combined with the effect of centrifugal and vibration compound. Results The excited force spectrum of shear model box was obtained, as well as the natural characteristics of shear model box in different overload and vibration environments. Conclusion The natural frequencies of shear model box decreased as a result of centrifugal effect, and the centrifugal load was the major influencing factor for the strength design of shear model box. |
