This article presents a mathematical model aimed at predicting wheel–rail contact vibration force arising from wheel profile irregularities. Prediction of vibrations caused by a passing train is a basic factor in environmental ...

Los mecanismos de levas conjugadas requieren de un ajuste con apriete para compensar las tolerancias de fabricación y montaje y al mismo tiempo evitar la separación de las superficies de las levas y los ...

El monitoreo de las condiciones de vibración es comúnmente utilizado para incrementar la disponibilidad de las maquinas en general, reduciendo consecuentemente los daños o fallas en las mismas, incrementar su vida útil, ...

In the higher pairs of a mechanism, like the one existing between a cam and roller follower, it is common to localize the maximum deformations, the maximum contact pressures and that appears the surface fatigue failure due ...

Due to dynamic effects, clearances, manufacturing and assembly errors in form-closed cam mechanisms, the follower jump can also occur. For conjugate cam mechanisms a technique to avoid the follower jump without the use of ...

En los mecanismos que incluyen barras y levas, en general el palpador de la leva es de rotación o de translación y posiciona algún elemento, a menudo una articulación, del mecanismo de barras. En el mecanismo que se estudia, ...

This paper presents an adaptive algorithm to reduce residual vibrations when the feedback sensor used has null drift along the time. The adaptive approaches are useful to deal with large variations of the system parameters ...

This work analyses the incidence of the parameter selection of B-spline curves, used in the design of displacement and motion functions, on its degree of freedom and shape. A complete design process based on the use of ...
