摘　　要：以STX-MAN 6S35ME-B9船用低速柴油机排气管尾部加装的SCR设备的反应器为研究对象,对该型SCR反应器进行多种工况的有限元强度计算,着重分析船舶在横摇22.5°时SCR反应器的最大等效应力以及安全系数。计算表明,各种工况下该反应器的设计满足强度要求,该结果对于SCR反应器在实船上的安装方案提供了依据。The SCR reactor is researched which is mounted on the tear of the exhaust pipe of one STX-MAN 6S35ME-B9 marine low speed diesel engine. The finite element strength of the SCR reactor under various operating conditions is calculated. The maximum equivalent stress and safety factor of the SCR reactor under rolling 22.5 degrees of the ship are analyzed. The calculation results show that the reactor＇s design meets the requirements of strength under various conditions. The results can provide instruction for the installation of SCR reactor in the real ship.
