Inverse Monitoring of Loading State with Output Measurements
Original language description
In many industrial cases it is difficult or very often even impossible to measure directly loading forces acting on the structure. In this kind of situations one possibility is to apply inverse monitoring principle. This means computation methods for determining forces from the output that the forces generate. This paper presents an application of the use of inverse computation method applied for determining the magnitude and location of loading forces on a structure. For the inverse computation presented method utilizes an influence coefficient approach. In this principle an influence coefficient matrix (ICM) that describes the relation between external loading forces and measured strains in the structure is used (Doyle). The elements of the matrix are in this case obtained from finite element (FE) model of the structure. One problem in the use of the inverse method is that it is very often ill-posed. In practice this means that small errors in strain measurement results can cause lar
