.... 09 02 2012 17 12 2012 An earlier study introduced the concept of piezoelectric energy-harvesting skin (EHS) to harvest energy by attaching thin piezoelectric patches onto a vibrating skin. This paper presents a methodology for the optimum design of EHS with the use of an efficient...

...Stefano Zucca; Christian Maria Firrone; Marco Facchini In order to reduce the resonant vibration of thin walled gears used for aeronautical applications, friction ring dampers may be added to the gear. In order to design the damper geometry, engineers must be able to evaluate its effect...

... representatives of all gear teeth because errors may occur in assembly procedure and affect tooth contact condition. Frequently, tooth surface measuring data cannot show contact condition and used to predict gear vibration accurately. Field inspection method whose measured results relate directly to the meshing...

...Bokman Lim; Frank C. Park One means of designing reduced vibration mechanisms is to ensure that the mechanism’s natural frequency be sufficiently greater than the driving frequencies of the actuators. In this paper we consider the problem of determining a mechanism’s mass, inertial, and joint...

... to the rocker. Oscillating gears driven by the rocker can cause serious vibration of the mechanism and shock loading between the teeth. In the proposed solution, however, the gears driven by the coupler suffer no such sudden reversals so that this problem is almost eliminated and a favorable reduction in shock...
