Minimizing residual vibrations for non-zero initial states: Application to an emergency stop of a crane
(Springer, 2013-11)
Article
Open AccessThis paper presents an approach to design command inputs for the reduction of residual vibrations in mechanical systems for nonzero initial states. The technique starts with the development of a standard input shaper in a ... -
A mathematical model to study railway track dynamics for the prediction of vibration levels generated by rail vehicles
(2012-01)
Article
Open AccessThis 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 ... -
Evaluation of the influence of a planned interference fit on the expected fatigue life of a conjugate cam mechanism- A case study
(2013-08-01)
Article
Restricted access - publisher's policyDue 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 ... -
Modified adaptive input shaping for maneuvering cranes using a feedback MEM gyroscope with null drift
(Springer, 2015-08-04)
Article
Open AccessThis 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 ... -
The use of hybrid CO2+MQL in machining operations
(2015-12-28)
Article
Open AccessNowadays, the environmental concern in machining industry is a fact. Because of that, in this article a new cooling-lubrication system which combines CO2 cryogenic and MQL technologies is presented. The aim of this new ... -
Use of single board computers as smart sensors in the manufacturing industry
(2015-12-28)
Article
Open AccessThe continuously growing presence of cyber-physical systems in the industry, especially in the field of processes automation and control, represents the paradigm of the so called fourth industrial revolution, in which the ... -
Avoiding early failures in conjugate cam mechanism by means of different design strategies
(2016-01-01)
Article
Restricted access - publisher's policyTo solve the indetermination of forces existing in a form-closed cam mechanism formed by conjugate cams, where the contact between the cams and the follower rollers is constantly ensured by only the geometry of the elements, ... -
Integration of product conceptual design synthesis into a Computer-Aided Design system
(2014-09-14)
Article
Restricted access - publisher's policyCommercial Computer-Aided Design systems have mainly focused to support the process of capturing and representing geometric shapes and incorporating technological information. In contrast, few utilities in these systems ... -
Radius of curvature and sliding velocity in constant-breadth cam mechanisms
(2014-11-01)
Article
Restricted access - publisher's policyIn constant-breadth cam mechanisms closure of the higher kinematic pairs formed by the bilateral cam-follower contact is guaranteed by the geometry of both cam and follower. A study of the cam profile by means of its radius ... -

Synthesis of displacement functions by Bézier curves in constant-breadth cams with parallel flat-faced translating and oscillating followers
(2013-04)
Article
Restricted access - publisher's policyThe constant-breadth cam mechanisms, which drive a parallel flat-faced double follower, are desmodromic, and guarantee global bilaterality. In the said mechanisms, the law of displacement of the follower can only be freely ... -
