Aiming at the fracture fault of rocker arm of a marine fin stabilizer,the paper theoretically analyzed the possible causes leading to the fracture fault and the stress and fatigue of the rocker arm with SolidWorks Simulation. The simulation results show that the security coefficients of the arm are not welldistributed and that the overall reliability is lower. The fracture location got by the simulation is consistent to the actual fracture location. The design of the arm was improved according to the simulation results. The improved arm can meet strength requirements and the security coefficients are well-distributed. The longterm voyage test proved that the new rocker arm can work well.
