COMPUTER IMPLEMENTED METHOD OF DETERMINING A TRANSFER FUNCTION OF A MODULE OR A COMPONENT AND GENERATING SUCH COMPONENT

The invention relates to a method of determining a transfer function (TRF) of a module (MDL). To improve accuracy of such methods the invention proposes the steps:a. measuring a first set-of-sensors-output (SO1) and a second set-of-sensors-output (S02) respectively using sensors (SS1, SS2) applied t...

More Information
Summary:The invention relates to a method of determining a transfer function (TRF) of a module (MDL). To improve accuracy of such methods the invention proposes the steps:a. measuring a first set-of-sensors-output (SO1) and a second set-of-sensors-output (S02) respectively using sensors (SS1, SS2) applied to said module (MDL),b. identifying parameters (ICH) relating to mass and/or inertia and/or damping and/or stiffness of said module (MDL) by rigid body estimation (RBE) from said measurements,c. fitting a first model (RB1) to identified inertia characteristics/parameters (ICH),d. generating a synthetic second set-of-sensors-output (ST2) of said second set-of-sensors (SS2) by said first model (RB1),e. comparing said synthetic second set-of-sensors-output (S02) with said measurements,f. estimating a Euler-angle correction (EAC) for said second set-of-sensors (SS2).
