Table 1 Equivalent spring stiffness of the components
Component | Structure model | Time-domain equation | Frequency-domain equation (L) | Equivalent spring stiffness |
|---|---|---|---|---|
Mass |
| \(f(t) = M\ddot{x}(t)\) | \(F(s) = Ms^{2} X(s)\) | \(Ms^{2}\) |
Spring |
| \(f(t) = kx(t)\) | \(F(s) = kX(s)\) | \(k\) |
Damping |
| \(f(t) = D\dot{x}(t)\) | \(F(s) = DsX(s)\) | \(Ds\) |
