Generic Bushing Model
The following describes a generic representation of a bushing model.
Let:
- t be the independent variable time
- p be a set of model coefficients or parameters used in the bushing definition
- x(t) be a set of internal states used in the bushing model
- u(t) be a set of known inputs provided to the bushing
- y(t) be the forces generated by the bushing (the outputs)
Then the general form of the equations representing a bushing is:
The functions F(…) and
G(…) depend on the bushing model that is
used. The above equations can be combined into one single expression having the
form:
