...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...

... of vibrations. This considerably minimizes the noise, wear and fatigue characteristics of machines, and improves their performance. Many high-speed machines contain planar mechanisms and the problem of their mass balancing is of continuing interest to machine designers. Different approaches and solutions have...
