        摘 要:由于工作環(huán)境的特殊性,船用斷路器不可避免地會(huì)受到艦船螺旋槳周期旋轉(zhuǎn)等引起的振動(dòng)載荷。采用有限元法建立了整個(gè)斷路器系統(tǒng)在振動(dòng)作用下的有限元?jiǎng)恿W(xué)模型,并通過加載真實(shí)的振動(dòng)載荷,對(duì)斷路器進(jìn)行動(dòng)力響應(yīng)分析。根據(jù)分析結(jié)果,對(duì)斷路器整體結(jié)構(gòu)強(qiáng)度和是否發(fā)生誤動(dòng)作出評(píng)價(jià),找出斷路器結(jié)構(gòu)敏感薄弱位置及變化規(guī)律,并對(duì)此進(jìn)行了結(jié)構(gòu)優(yōu)化設(shè)計(jì)。

        Abstract: It is inevitable that the marine circuit breaker will be affected by vibration load caused by ship propeller periodic rotation because of its special working environment. The finite element method is applied to build a finite element dynamic model when the whole circuit breaker system is under vibration, and dynamic response of the circuit breaker is analyzed by loading real vibration load. The authors,according to the analyzed results, evaluate the overall structural strength of the circuit breaker and the occurrence of misoperation, find out the sensitive weak position of the circuit breaker structure and their variation laws, and optimize structural design of marine circuit breakers.
        Key words: marine circuit breaker; vibration; finite element dynamics; structural optimization
