Abstract :
Based on the theory of twisted lever-arm effect, this paper provided a new model for the lever-arm effect caused by the shipboard weapons´ transfer-alignment, not considering the dynamic twist. Deflection angle of the second-order Markov process model was established and set up in simulink. Composed with the non-twisted lever-arm effect, the result showed that the acceleration error caused by dynamic twist was large and need compensated.
