Recent Advances in Shock Vibration Isolation: An Overview and Future Possibilities
(2019-01-01)
Mechanical shock is a common problem that is present in many situations, such as ground motion, blast, explosions, crash, and impact. The development of passive, active, or adaptive control and isolation strategies for ...
Some diverse examples of exploiting the beneficial effects of geometric stiffness nonlinearity
(2019-06-15)
The effects of nonlinearity, particularly stiffness nonlinearity, has been of concern to structural engineers for many years. The main reason for this is because this type of nonlinearity can cause unpredictable dynamics, ...
Optimization of Axial Vibration Attenuation of Periodic Structure with Nonlinear Stiffness without Addition of Mass
(2020-12-01)
We explore the vibration attenuation of a periodic structure when one absorber with nonlinear cubic stiffness is included without increasing the total mass. Metastructures, and specifically periodic structures, present ...
ON ACTIVE SYNCHROPHASING CONTROL OF VIBRATION FOR A FLOATING RAFT VIBRATION ISOLATION SYSTEM
(Int Inst Acoustics & Vibration, 2015-01-01)
A floating raft vibration isolation system installed on a flexible hull-like structure is described in this paper. Four vibration exciters, in which two counter rotating shafts with the same balanced masses are driven by ...
On synchrophasing control of vibration and sound radiation for a floating raft vibration isolation system
(2014-01-01)
For the purpose of solving the problems of vibration transmission and sound radiations in ships, synchrophasing control technology was presented. The phases of multiple rotating or reciprocating machines installed on a ...
An Alternative Approach to Substructuring in Vibratory Systems Containing Soft Rubber Isolators
(Asme, 2019-12-01)
Built-up structures, such as airplanes, ships, and even refrigeration systems, which have many components, can be substructured to speed up and facilitate the process of calculating the vibratory response of the complete ...
Stiffness nonlinearity in structural dynamics: Our friend or enemy?
(2017-04-25)
The effects of nonlinearity, particularly stiffness nonlinearity, has been of concern to structural engineers for many years. Primarily this has been because this type of nonlinearity can cause unpredictable dynamics, and ...
Active vibration isolation of a diesel generator in a small marine vessel: An experimental study
(2020-05-01)
An active vibration isolation system is retrofitted to a diesel generator set in a tugboat to determine the effectiveness of such a system in a realistic practical environment. The system consists of six bespoke inertial ...
Fundamental analysis on the intentional use of nonlinear stiffness in some dynamical systems
(2019-01-01)
Although nonlinearity in dynamical systems have been of concern for many years due to its unpredictable effects, researchers and engineers have recently begun to incorporate it into mechanical and mechatronic devices to ...
