Contact Force Decomposition Using Contact Pressure Distribution
IEEE Robotics and Automation Letters, 2017Many robotics applications involving contact with objects require the decomposition of an external force measured by a force sensor into its normal and shear components. In this paper, we present a general and effective contact force decomposition method based on the contact pressure distribution.

Electrostatic and contact forces in force microscopy
Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 1991We have been measuring the electrostatic and contact forces between a tip and a graphite surface in a force microscope, which uses a polarizing optical interferometer. For large distances where the electrostatic force predominates, the data are analyzed in terms of a model which introduces the elongated shape of an actual tip.

Dissipative Contact Force Models
2016In this chapter, some of most relevant dissipative contact force models utilized in multibody dynamics are presented. In particular, attention is given to the constitutive laws proposed by Kelvin and Voigt, Hunt and Crossley, Lankarani and Nikravesh, and Flores et al. Additionally, other nonlinear contact force models are briefly presented. The contact

Electromagnetic forces on contacts
2008 43rd International Universities Power Engineering Conference, 2008These instructions give you basic electromagnetic force on an arcing contact is one of the principal factors in designing large-capacity and small-sized high current contact systems of circuit breakers, disconnectors or isolated switches. Butt contacts, such as those in vacuum interrupters, tulip contacts structured from a rod contact and fingers are ...

This paper reviews contact modeling with an emphasis on the forces of contact and their relationship to the geometrical, material and mechanical properties of the contacting bodies. Single asperity contact models are treated first. These models include simple Hertz contacts for spheres, cylinders, and ellipsoids.

Nanotechnology, 2005
We propose a step-by-step experimental procedure for characterization of the nonlinear contact stiffness on surfaces using contact-mode atomic force microscopy. Our approach directly estimates the first-, second-, and third-order coefficients of the contact stiffness.

In the previous chapter, we looked in some detail at gravity, which is a force that acts at a distance. Except for gravity, however, most of the forces that we encounter in our daily lives arise from direct contact with other objects, either solids or fluids.

ROLLING CONTACT FORCE ENERGY RECONSTRUCTION
Journal of Sound and Vibration, 2000Abstract Knowledge of the forces at the wheel–rail contact is fundamental to estimate the consequences in terms of noise and vibration. The traditional use of strain gauges mounted on the wheel web and axle is not capable of determining the high-frequency content of the contact force.

Pantograph/Catenary Contact Force Control
Volume 6: 11th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2015In this paper, a new continuum-based pantograph/catenary model based on the absolute nodal coordinate formulation (ANCF) is proposed and used to develop an effective method to control the contact force which arises from the pantograph/catenary interaction.

Numerical Methods for the Force Reflection of Contact
Journal of Dynamic Systems, Measurement, and Control, 1997An important problem in the field of force-reflecting systems and telerobotics is poor rendering of contact, particularly of contact with stiff surfaces. There are numerous possible sources of poor performance, including poor contact models, sampling errors, and delays due to computation or data transmission.
