Most of existing methods for force identification assume the force locations to be known a
priori. In this paper, we propose a novel recursive algorithm, named sparse Kalman filter, to …

Locations and amplitudes of external forces are essential information for design, loading
assessment, and health monitoring of structures. In this paper, we propose an original time …

To ensure the accurate analysis and evaluation of structural integrity and vibration
responses, a novel technique is required for load identification with minimal error …

In this work, reconstruction and location in time domain of multiple forces acting on a linear
elastic structure are achieved through a Bayesian approach to solve an inverse problem …

In this paper, we propose a two-step iterative approach to both localize and reconstruct a
single point force acting on a structure. Since force reconstruction problems are typically ill …

An accurate input-output mathematical model is the basis of moving force identification
(MFI). However, an absolutely accurate mathematical model between moving forces and …

Traditional time domain force identification methods require prior knowledge about the force
profile to apply the appropriate regularization term. Generally speaking, ℓ 1 and ℓ 2 …

Many engineering applications require the knowledge of input forces to mechanical
systems. However, in practice, it is quite difficult to measure these forces directly. In order to …

The accuracy and effectiveness of force identification in time domain based on state space
can be influenced by the conditioning of the structural system Markov parameter matrix. Two …

Several engineering applications demand in-operation dynamic forces exerted on structural
components to be modeled, however there are cases in which both phenomenological and …
