The invention discloses a large-scale self-propelled ship model testing method based on force similarity, and relates to the field of ship model tests.According to the method, when a large-scale self-propelled ship model corresponding to a real ship is machined, a forcing force compensation device is installed at the stern of a ship model body, and the forcing force compensation device comprises a ducted fan; a ducted fan is arranged on the ship model body, an air outlet of the ducted fan faces the bow part of the ship model body, then a navigation test is carried out, and frictional resistance correction is carried out at different ship model navigational speeds by controlling the working process of the ducted fan, so that the requirement of resistance similarity between the large-scale self-propelled ship model and a real ship is met; the scale effect influence of the large-scale self-propelled ship model test is reduced, and the forecasting precision and reliability of the large-scale self-propelled ship model test are improved.

    本申请公开了一种基于力相似的大尺度自航船模测试方法,涉及船模试验领域,该方法加工实船对应的大尺度自航船模时在船模本体的艉部安装有强制力补偿装置,强制力补偿装置包括涵道风扇,且所述涵道风扇的出风口朝向所述船模本体的艏部,然后再开展航行试验,通过控制涵道风扇的工作过程以在不同的船模航速下进行摩擦阻力修正,从而使得大尺度自航船模与实船之间达成阻力相似的要求,减小了大尺度自航船模试验的尺度效应影响,提高大尺度自航船模测试的预报精度和可靠性。
