Abstract

This paper presents an investigation into the mathematical modelling of the dynamics of a generic candidate inceptor mechanism when system linkage flexibilities are represented. The lumped parameter approach for modelling the flexibility is proposed and applied within the multi-body dynamic modelling framework formulated by Udwadia-Kalaba to explore system resonances. A low-order multi-body mathematical model of an inceptor system is derived and frequency response characteristics numerically obtained. Through a parametric design study, results show how resonance frequencies can be tuned to meet specified levels by identifying and recommending modifications in system design configurations at early design stages. The work presented in this paper provides a framework to identify acceptable design configurations of a system and offers parametric design insights within a multi-body dynamic environment.
