Random Vibration Analysis of Train Moving over Slab Track on Bridge under Track Irregularities and Earthquakes by Pseudoexcitation Method

Table 6

Evaluation standards for train operation stability.

Evaluation indices	Unit	Allowable limit
Carbody vertical acceleration	m/s^2	1.30
Carbody lateral acceleration	m/s^2	1.00
Lateral wheelset force for motor car	kN	53.83 (= 0.85 × (10 + /3)
Lateral wheelset force for trailer car	kN	49.87 (= 0.85 × (10 + /3)
Wheel load decrement ratio	—	0.65

denotes the static wheelset load, which is equal to 160.0 kN and 146.0 kN for motor car and trailer car in this paper, respectively.
