Improved Multibody Dynamics for Investigating Energy Dissipation in Train Collisions Based on Scaling Laws

Table 5

Velocities of bodies at stable time.

	Stable time (s)	Velocity (m/s)
		Moving car	Car 1	Car 2	Car 3	Car 4	Car 5
Experiment	0.143	3.065	3.086	3.087	3.075	3.080	3.085
IMM	0.164	2.902	2.887	2.881	2.881	2.895	2.904
TMM	0.176	2.978	2.980	2.975	2.982	2.984	2.986

Stable time: the time when moving car’s speed is equal to cars and after that moment moving car’s speed is smaller than cars and honeycombs.
