Abstract: A method of calibrating stiffness of support structures of an assembly including a main structure and support structures includes modeling the assembly using finite elements, with a theoretical stiffness of the support structures, in moderate support load conditions, calculating calculated reaction forces for each support structure and measuring corresponding measured reaction forces. The stiffness of each support structure is calibrated by determining a calculated stiffness of each support structure based on comparison between the calculated reaction forces and the measured reaction forces. The modeling and simple measurements during an operational phase, in which the support loads are moderate, thus enable the calibration of the stiffness of the support structures. An associated method of modeling the assembly and a corresponding computer program are also disclosed.
