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