The invention discloses a berth launching method based on load hysteresis optimization, and the method comprises the steps: carrying out the statistics and analysis of an actual launching dangerous position of a ship through employing the stress monitoring data of the ship launching at the same berth, comparing the ship launching dangerous position calculated through employing a statics theory, analyzing the hysteresis of the load transmission of the ship launching, and obtaining the ship launching lag distance. And correcting a theoretical calculation dangerous position of novel ship launching on the same slipway by using the measured actual lagging distance of ship launching on the same slipway, and designing a ship launching reinforcing support arrangement according to the corrected most dangerous position. According to the method, the influence of ship movement on ship launching is considered, the hysteresis of ship launching load transmission is analyzed, the inconsistency between the most dangerous position calculated through ship launching analysis and the actual ship launching most dangerous position is measured, the error between the ship launching reinforcing support arrangement position and the actual ship launching most dangerous position is reduced, and the ship launching safety is improved. And the launching strength of the ship is relatively safe.

    一种基于载荷滞后性优化的船台下水方法,利用船舶在同一船台下水的应力监测数据,统计、分析船舶实际下水危险位置,对比应用静力学理论计算的船舶下水危险位置,分析船舶下水的载荷传递的滞后性,获得船舶下水滞后距离。应用测量的船台下水的实际滞后距离修正在同一船台新型船舶下水的理论计算危险位置,根据修正后的最危险位置设计船舶下水加强支撑布置。本发明考虑了船舶运动对船舶下水的影响,分析了船舶下水的载荷传递的滞后性,测量了船舶下水分析计算出的最危险位置与实际船舶下水最危险位置的不一致性,缩小了船舶下水加强支撑布置位置与实际船舶下水最危险位置的误差,使得船舶下水强度偏于安全。
