Control Strategy of the Brake Dynamics for Railway Vehicles Equipped with Anti-Slip-Device [PDF]

open access: yes, 2006
From the point of view of railway vehicle braking processes it is an important requirement to maintain the roll-ing-motion-state of the wheels, i.e. the macro-sliding-free rolling contact between the vehicle wheels and the rail-head, since in the course ...

A novel methodology to automatically include general track flexibility in railway vehicle dynamic analyses

open access: yes, 2020
The interaction between the rolling stock and the infrastructure plays a crucial role in railway vehicle dynamics. The standard approach consists of using a multibody formulation to model the railway vehicles running on simplified tracks. The track model

Communication of Business‐Nonprofit Collaborations and Environmental Legitimacy: Exploratory Insights From Italian Firms

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Collaborations with nonprofits can enhance firms' legitimacy, yet the relationship between their communication and corporate environmental legitimacy remains poorly understood. Furthermore, research lacks an analysis of the communication of business‐nonprofit collaborations through multiple actors' perspectives.

Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.
