Method for Predicting Barge Impact Force Based on Nonlinear Spring Stiffness

Table 3

The sample points for fitting.

Case
Key point	C-500-3	C-1000-3	C-1200-3	C-1000-2	C-1000-4.5
1	19.20	19.47	19.52	16.46	20.58
2	8.52	8.59	8.60	9.42	9.44
3	5.72	5.75	5.74	6.58	4.06
4	1.14	1.39	1.37	1.23	1.40

C-P1-P2: P1 is barge mass; P2 is impact speed. For example, C-500-3 is the case of barge impact rigid wall with barge mass 500 t and impact speed 3 m/s.
