rolland.components.ContPad

class rolland.components.ContPad(*args, **kwargs)[source]

Bases: HasTraits

Cont Pad Class.

Contains the properties of a continuous pad.

Parameters:

  • args (t.Any)

  • kwargs (t.Any)

sp

Vertical/lateral pad stiffness (per meter) \([N/m^2]\). Lateral value can be set to zero when lateral rail deflections are omitted.

Type:

list of float

etap

Pad loss factor \([-]\).

Type:

float

fresp

Vertical/lateral pad resonance frequencies \([Hz]\). These frequencies are needed for calculating the viscous damping coefficients if they are not provided. Lateral value can be set to zero when lateral rail deflections are omitted.

Type:

list of float

dp

Vertical/lateral viscous damping coefficient (per meter) \([Ns/m^2]\). Lateral value can be set to zero when lateral rail deflections are omitted.
