Analysis of Impact Resistance of Floating Raft Vibration Isolation System
To reduce the impact on the ship's equipment and enhance the impact resistance of the floating raft vibration isolation system,a finite element model is established based on the ship's floating raft vibration isolation system,and a simulation analysis is conducted.The structural parameters of the system,impact input,and response are obtained by experimental measurements to verify the accuracy of the established finite element model.Standard impact loads are derived according to the BV043/85 specifications,and a time-domain simulation method is used to perform finite element analysis on the system,investigating the effects of design parameters on the impact resistance characteristics of the floating raft system.The study shows that the thickness and mass of the plates have a significant effect on the maximum stress experienced by the floating raft,but a relatively small effect on the damping of the system's impact response.The damping of the isolators is found to be sensitive to impact damping.In addition,the stiffness of the isolators is found to be negatively correlated with the damping performance of the system.The simulation and experimental results on the impact resistance characteristics of the floating raft provide guidance for its impact resistant design and engineering applications.
