Abstract

The research presented in the current paper focuses on the analysis of the model uncertainty in the static part of hydraulic damper models. Recently established experimental and identification methodology provides non-parametric estimates of the overall static characteristics of velocity-sensitive hydraulic dampers. Previously identified non-parametric static characteristics of a helicopter hydraulic damper are investigated in this paper. A model uncertainty is presented in the form of two alternative pressure-flow models that are considered herein. The main goal of this paper is to assess the feasibility of a non-parametric static representation of the damper in its ability to indicate the actual fluid flow topology and the flow regimes established by the experimental conditions.
