Mechanical joints can have significant effects on the dynamics of assembled structures. The goal of our work is to develop physics based, reduced-order, finite element models that are capable of replicating the effects of joints on vibrating structures. Various studies have shown that micro- and ...

The performances of the ROMs are assessed by conducting nonlinear modal analysis and computing a posteriori error metrics. Introduction The study of mechanical joints, and interfacial mechanics more broadly, has been a topic at the forefront of advances in efficiency and design within the aero-...
In this paper we study the modeling and control of robot manipulators with elastic joints. We first derive a simple model to represent the dynamics of elastic joint manipulators. The model is derived under two assumptions regarding dynamic coupling between the actuators and the links, and is usefu...
Modeling the dynamics of such complex systems requires a deep understanding of mechanical principles, kinematics, and control theory. Additionally, the nonlinear and often unpredictable nature of robot dynamics further complicates the modeling process, as it mayrequire advanced mathematical techniques and ...
