Avoiding early failures in conjugate cam mechanism by means of different design strategies
(2016-01-01)
Article
Accés restringit per política de l'editorialTo 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, ... -

Dynamic analysis of impact in swing-through crutch gait using impulsive and continuous contact models
(2012-09-01)
Article
Accés restringit per política de l'editorialThe dynamics associated with the impact of the crutch with the ground is an important topic of research, since this is known to be the main cause of mechanical energy loss during swing-through gait. In this work, a ... -

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
Accés restringit per política de l'editorialDue 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 ... -
Integration of product conceptual design synthesis into a Computer-Aided Design system
(2014-09-14)
Article
Accés restringit per política de l'editorialCommercial 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 ... -
Minimizing residual vibrations for non-zero initial states: Application to an emergency stop of a crane
(Springer, 2013-11)
Article
Accés obertThis 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 ... -
Modified adaptive input shaping for maneuvering cranes using a feedback MEM gyroscope with null drift
(Springer, 2015-08-04)
Article
Accés obertThis 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 ... -

Radius of curvature and sliding velocity in constant-breadth cam mechanisms
(2014-11-01)
Article
Accés restringit per política de l'editorialIn 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 ... -
