Abstract

A method is provided for estimating the components of the force torsor that are applied to a bearing, which method provides for the measurement of a vector (V.sub.m) of N deformations and for the use of a physical model linking a vector (Q) of at most N representative values of the components of the torsor with a deformation measurement vector, the method comprises the following iterative steps: introduction of a vector (Q) of representative values into the model in order to calculate a deformation measurement vector (V.sub.c); and carrying out a pertinence test (T) between the deformation measurement vector (V.sub.c) which is calculated and the measured vector (V.sub.m); if the test (T) is negative, establishing at least one new vector (Q) of representative values to be introduced into the model according to the result of the test; or if the test (T) is positive, storing the vector (Q) of introduced values; wherein the estimated components of the force torsor are established according to at least one stored vector (Q) of values.
