Research On Meta Synthesis Mast's Vibration Character And Connection Structure Intensity

Because of meta synthesis mast's characteristic and higher structure strength, meta synthesis mast is more and more adopted in the domestic and international warship. Composite material is adopted in meta synthesis mast. There are not rules about composite materials, so we can't find rules to design.Taking the boundary condition according to the criterion .We may obtain nearly accurate vibration modal, but the establishment of model need too much time. Simplifying the actual boundary to the rigid constraint, the error of the result is big, therefore the author uses elastic constraint to describe the boundary condition, this article produces the method to confirm stiffness coefficients, and carries on the modal analyze, the results could satisfy the project actual request, the time of analysis can be reduced.The meta synthesis mast's bottom structure takes bolt connection with the use of simple, fatigue resistance, connecting the integrity and good stiffness advantages. Bolt connecting structure of the widespread adoption of a connection, but of composite materials and steel connection is in a special connectivity, it is necessary to carry out their specific analysis of the study. A single bolt is simulated by using finite element software in the rally under the stress of the situation.This article design the bottom connecting structure of meta synthesis mast application of finite element software in accordance with a single bolt of numerical simulation of the single row at the bottom of connecting bolts and more complex structure of numerical calculation, and the results are checking. The bottom connection structure of composite material tube mast can meet the needs of project.
