The increasing use of simulation for both circuit and component analysis in the aircraft industry has come about due to the requirement for acceptable transient as well as steady state performance of aircraft systems. The computer simulation package, Bathfp, developed at the Fluid Power Centre, University of Bath, is suitable for investigations into both of these. Utilities are provided which allow a model of a complicated system or component to be built up from its elements, which can be introduced to the model library of components so that particular dedicated areas of interest such as flight control actuation systems and braking and landing gear may be examined in detail. Component models enable the internal details of valves, pumps, motors, actuators and other elements to be simulated to a high degree of accuracy.

    This paper describes the application of the simulation package to perform a detailed analysis of the bi-stable valve in the A340 landing gear shock absorber. In the original design, a malfunction of the valve during impact on landing was clearly identified by an experimental test. Parametric variations are made in the simulation to identify the possible cause of the malfunction.
