Numerical Modelling of Rubber Vibration Isolators
An important cause for interior noise in vehicles is structure-borne sound from the engine. The vibrations of the source (engine) are transmitted to the receiver structure (the vehicle) causing interior noise in the vehicle. For this reason the engine is supported by rubber isolators for passive isolation in especially the high-frequency region. To make a good judgment of the characteristics of...
متن کاملDevelopment of New Control Techniques for Vibration Isolation of Structures using Smart Materials
In this paper, the effects of the restoring force device on the response of a space frame structure resting on sliding type of bearing with a restoring force device is studied. The NS component of the El Centro earthquake and harmonic ground acceleration is considered for earthquake excitation. The structure is modeled by considering six-degrees of freedom (three translations and three rotation...
متن کاملDecentralized control for multichannel active vibration isolation
This paper describes a theoretical and experimental investigation into an active four-mount vibration isolation system, in which electromagnetic actuators are installed in parallel with each of the four passive mounts placed between a three-dimensional piece of equipment and a vibrating base structure. Decentralized velocity feedback control is applied, where each actuator is operated independe...
متن کاملVibration Isolation of Precision Objects
The need for vibration isolation of precision and vibrationsensitive objects is increasing continuously. Vibration isolation systems must comply with contradictory specifications, such as requiring reduced stiffness of isolators for better isolation, but higher stiffness for better performance of the object. Recently, expensive active isolation systems have been used to resolve these contradict...
متن کاملNUMERICAL MODELLING OF RUBBER VIBRATION ISOLATORS: identification of material parameters
Rubber vibration isolators are used for vibration isolation of engines at high frequencies. To make a good prediction regarding the characteristics of a vibration isolator in the design process, numerical models can be used. However, for a reliable prediction of the dynamic behavior of the isolator, the rubber material parameters have to be known. In practice the material parameters have to be ...
