Rosetta Stone version 3 Using incremental mode sup

Using incremental mode superposition method with limit of nonlinear shock response Isolation System

Hit Response is also smaller. Unit l and raft the gap between the stopper and the rigidity of the system impulse response of the raft with the unit 2 and the gap between the stopper and the rigidity of the system impulse response similar. 4 Conclusion In a ship with a limiter device impulse response analysis of the impact should be considered when calculating the stiffness of the process of mutation, that is,[link widoczny dla zalogowanych], the system should be considered non-linear, and therefore can not directly use mode superposition method or the impact of spectrum analysis method response. This incremental mode superposition method will be applied to the ship with a stopper Isolation System Shock Response, the following conclusions: (1) whether there is an infinite-bit device, with the incremental mode superposition method are floating raft raft system and the acceleration unit impulse response, the measured acceleration with the basically the same impulse response. Acceleration response for the raft to calculate the maximum value slightly smaller than the experimental value, while the unit is slightly larger than the maximum acceleration response of the experimental values calculated, the maximum relative error is 14.04%. That the incremental mode superposition method to calculate the impact of floating raft isolation system response is feasible. (2) In the floating raft isolation system installed at different locations limiter, and the raft will be on the unit's maximum acceleration and maximum displacements have different impacts. Between the foundation and install the stopper raft after raft displacement are obvious limitations, while the maximum displacement of the corresponding response unit also declined, however, the raft units and the maximum acceleration response but had been increased, This conclusion is consistent with experimental findings obtained. Between the unit and install the stopper raft after the raft unit and the unit and the displacement between the restrictions have been effective, while the raft and the maximum acceleration response unit and the maximum displacement response of the raft are significantly increased. Between the base and the raft and the raft and the crew are installed between the stopper after the displacement of the unit the most obvious control of the raft and the raft and the displacement of the displacement between the various units have also been certain restrictions , while the largest units and the raft has a corresponding acceleration response has improved a lot. (3) and the raft for the crew between the limiter, reducing the gap and increase its stiffness can limit the displacement of the unit, but will lead to the largest unit and the raft of changes have a greater acceleration response, while raft little effect on the displacement response, the impact on other units of the response is also smaller.
