Some predicted a final elastic vibration between negative displacement limits (implying a final displacement in the direction opposite to the load), while others predicted positive limits.
To this diagram, the following comments can be made: In the case of small initial displacements the beam material remains elastic and the beam carries out elastic vibrations around the equilibrium position w = 0; the curves (a) and (b) coincide.
The elastic vibration of car body is a serious problem as the increasingly speed and lightweight design of car body.
In addition to the inertia force caused by the rigid body motion of a flexible mechanism, the inertia force due to the elastic vibration of flexible links plays an important role in the dynamics of flexible mechanisms and so should be eliminated.
The Pusher Centrifuge SZ is quick and easy to install, being placed directly onto elastic vibration dampers which means that a vibration foundation is not required.
Elastic vibration has a greater impact on the accuracy and quality of the operation in the system [2, 3], for example, the elastic vibration of pick-and-place parallel manipulator in food packaging, directly affecting the quality of food [4]; the vibration of operating mechanism at the end of picking manipulator, leading to instability in grasping and damage to strawberry, tomatoes, and other soft appearance fruits [5, 6].
[DELTA][X.sub.P], and [DELTA][Y.sub.P], [epsilon] are translational and rotational declinations of the moving platform because of elastic vibration of the flexible links.
To analyze the active suppression of elastic vibrations with the development of destabilization processes in the case of astatic regulation in terms of CP (I) is difficult because of the many options for combining parameters and particular solutions.
Experimental setup was designed and made to investigate part alignment when elastic vibrations were applied to the peg (Fig.
The vibrators are attached to the plate and excited by the frequency, aiming to cause elastic vibrations of the plate.
One of the being assembled parts may be excited by the low frequency vibrations, causing the part to vibrate like a solid body, or elastic vibrations of the part may be forced.
Each part of the platform is excited by autonomous high frequency (piezoceramic) vibrators, causing elastic vibrations of the mentioned parts.
