摘　　要：基于光纤Bragg光栅技术,对船舶下水时横梁受力进行测试,并将测试结果同理论计算进行对比分析。结果表明,4 250 TEU集装箱船采用现有船台、双滑道纵向下水工艺是安全的,将光纤Bragg光栅技术应用于船舶下水横梁的受力测试是可行和有效的。Based on the technology of fiber Bragg grating sensor （FBG） , dynamic load on the balance beam for vessel launching are measured and compared with that obtained from theoretical calculation. The results show that it is safe for 4 250 TEU containership to use the existing shipbuilding berth and adopt longitudinal launching process with two slideways. FBG technology is a feasible ＆ effective method for dynamic forces testing.
