Modeling of Elastic Robot Joints with Nonlinear Damping and Hysteresis
Elastic robot joints gain in importance since the nowadays robotics tends to the lightweight structures. The lightweight metals and composite materials deployed not only in the links but also in the joint assemblies affect the overall stiffness of robotic system. The elastic joints provide the loaded robot motion with additional compliance and can lead to significant control errors and vibratio...
متن کاملModeling and frequency domain analysis of nonlinear compliant joints for a passive dynamic swimmer
In this paper we present the study of the mathematical model of a real life joint used in an underwater robotic fish. Fluid-structure interaction is utterly simplified and the motion of the joint is approximated by Düffing’s equation. We compare the quality of analytical harmonic solutions previously reported, with the input-output relation obtained via truncated Volterra series expansion. Comp...
متن کاملModeling Rocky Scenery Taking into Account Joints
Research on methods for representing natural objects and phenomena by computer graphics (CG) has been steadily broadening the scope of represented objects in recent years. Among such research, visual simulation of rocky scenery is an important issue that has a wide range of applications related to visual contents, such as in landscape simulation. In the early days of research on terrain scenery...
متن کاملNonlinear Dynamics and Control of Crank-Slider Mechanism with Multiple Clearance Joints
In the current study, behavior of crank-slider mechanism with single and multiple clearance joints are analyzed. Using Lankarani-Nikravesh theory for estimating discontinuous contact forces in clearance joints, relevant systems have been mathematically modeled. Through numerical simulations, perturbations in response of mechanisms with clearance joints have been analyzed. Effects of increasing ...
