The invention discloses a ship performance analysis method, which is characterized by comprising the following steps of: obtaining data according to static forward floating sailing of a ship; checking the initial stability of the ship, and checking the stability of a large dip angle and the initial stability; the method comprises the following steps of: firstly, calculating the stability of a large dip angle of a ship, drawing an oblique line on a musk cross section after the ship is subjected to external force and the left and right dip angles of a ship body exceed the stability, calculating the stability of the large dip angle of a water outlet edge and a water inlet edge of each section of the musk cross section, and drawing a stability cross section curve; analyzing the floating state, the initial stability, the water inlet angle, the dynamic stability and the like of the ship under the action of various loads; the stability balance number of the ship is calculated, and a hydrostatic curve graph is drawn; and drawing a hydrostatic curve graph by combining hydrostatic curve calculation, initial stability checking, large-dip-angle stability calculation and stability balance number to obtain a performance analysis result of the ship.

    本发明公开了一种船舶性能分析方法,其特征在于,所述方法如下:根据船舶静态正浮航行所得的数据;对船舶的初稳性进行校核,对大倾角稳性的检查和初稳性的检查;对船舶的大倾角稳型进行计算,在船舶受到外力作用后,船体左右的倾角超过时的稳性时,在乞氏横剖面上画一条斜线,并对其各段的出水、进水边进行大倾角稳定的计算,并绘出稳性横截曲线,其次,对船舶在各种载荷作用下的浮态及初稳性、进水角和动态稳性等进行分析;计算船舶的稳性衡准数并绘制静水力曲线图;结合静水力曲线计算、初稳性校核、大倾角稳型计算、稳性衡准数、绘制静水力曲线图得出船舶的性能分析结果。
