The amount of leakage is the only direct indicator of the sealing performance of a proton
exchange membrane fuel cell (PEMFC). In this work, a predictive model is developed to …

Under accident conditions, the sustained high temperature and high pressure (HTHP)
environment within the containment structure poses a threat to the penetration seals. This …

Nowadays, underground equipments are widely applied to explore oil resource in deep
earth. Static seal rings are important components keeping underground equipment working …

In service, thermal–mechanical coupling conditions can exacerbate stress relaxation of O-
rings and lead to their thermal expansion, further complicating the sealing problem. A finite …

Purpose This paper presents an experimental and numerical study to evaluate the impact
energy dissipation, proposing a dry friction damper using spherical elements as a …

We studied the properties of cubic nonlinear systems with dry friction damping on the
prospect of 'non-resonance'. An approximate method was used to get the frequency …

En este trabajo se analiza experimentalmente el funcionamiento de un dispositivo tope de
impacto como atenuador de vibraciones de un sistema sometido a vibración forzada. Para …

Esta investigación está centrada en el estudio numérico mediante el método de elemento
finito de un disipador pasivo de pared delgada con esferas como elementos de fricción seca …
