Table 2
The parameters of the monolithic nonballasted track.
| Components of track | Parameters | Magnitude |
| Steel rail | Young’s modulus /(N⋅m−2) | 2.06 × 1011 | Area moment of inertia /(m4) | 3.22 × 10−5 | The mass in one meter /(kg⋅m−1) | 60.64 |
| Rail pad | The stiffness /(N⋅m−1) | Variation with amounts and the frequencies of loads | The damping /(N⋅S⋅m−1) | 7.5 × 104 |
