Impact Force Evaluation of the Derailment Containment Wall for High-Speed Train through a Collision Simulation

Table 5

Summary for the effects of the containment wall.

Parameter	Case	Impact force (kN)	Remark
Effect of D	Case 1	160–1,500	Reducing distance effect
	Case 2 and 3	600–4,000	Uncertain distance
	Case 4	Reduced value	Guided effect by running rail
Effect of hR	Case 5	3,200–4,100	Increasing height/uncertain distance
	Case 6	1,168	Increasing height/reducing distance
	Case 7	500–850	Reducing height and distance
Alternative method	Case 8	100–250	Within track gauge
