The vibration is caused by the excitation force in the piston chamber. The excitation force acting on the cylinder blocks with the set of pistons has the great impulse on the dynamic response. In the local coordinate system OC-XCYCZC, the force and moment acting on the rotor assembly can ...
Van der Waals force is an attractive force between two atoms or nonpolar molecules, which arises because a fluctuating dipole moment in one molecule induces a dipole moment in the other, and the two dipole moments interact [31]. From: Materials Science in Semiconductor Processing, 2022 About thi...

In contrast, we take an alternative approach to pHRI that induces the person receiving aid to engage sensorimotor processes to alter their own gait. Our approach is inspired by examples of low-force physical human–human interaction (pHHI) at the hands during walking. We define “low” magnitud...
Jean Cousteix, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 II.B Forces on the Body Now, let us consider the surface of a solid in contact with a fluid (Fig. 3). In an inviscid flow, along a surface element dσ the fluid exerts a pressure force on the ...
the friction pair: the components and their relevant properties of mechanical, physical, chemical aspects and geometry; ■ the interface: the formation and breakaway of contact junctions in multiple scales; ■ the operational variables: load (pressure) and speed and time; ■ the environmental variabl...
Since it was invented by Binnig et al in 1986, atomic force microscopy (AFM) has played a crucial role in nano-scale science and technology. AFM is a micro... Y Seo,W Jhe - 《Reports on Progress in Physics》 被引量: 93发表: 2008年 Spectroscopy of the anharmonic cantilever oscillations...
During the PEMFC operation process, the internal operating conditions in fuel cells involve multiple physical fields, such as the force field, thermal field, and humidity field, which are coupled with each other. The distribution of temperature, humidity, component deformations, and contact pressure ...
