Abstract
A landing gear is a good example of a highly nonlinear multidisciplinary system. Using hybrid modelling, nonlinear behaviour can be abstracted to discontinuous behaviour. Bond graphs are an established and intuitive method for constructing mathematical models of multiphysics dynamic systems. The Hybrid Bond Graph is therefore used here to demonstrate the modelling of a landing gear drop test. A distinction is drawn between structural and parametric discontinuities, represented using controlled junctions and elements. Causally static and dynamic bond graphs are compared. A mixed Boolean mathematical model is obtained from the causally dynamic graph.
