Vibration Characteristic Research of a Small Waterplane Area Twin Hull

ZHANG Xu （China Ship Development and Design Center，Wuhan 43o064，China）

Abstract： The special structure characteristic and overall vibration speciality of small waterplane area twinhull ship（SWATH）aredescribed in the paper. With finite element method，overallvibration modecalculation was carried out，the overallvibrationcharacteristicofSWATHwas studied，alsothe vibrationperformanceofcriticalarea was studied，some meaningful results of SWATH overall vibration calculation andoverallvibration characteristic wereobtained asreferencesforsimilarcalculations.

Keywords：SWATH;overall vibration; finite element analysis

船舶振動性能主要取決于船舶的固有總振動頻率是否與激振力頻率有足夠的錯開率及船舶重點區(qū)域在激勵下的振動響應，振動性能對于船舶安全、船上人員工作及設備運行環(huán)境均有重要影響，是船舶的重要性能之一。（剩余4892字）
