Engine Mounting Characteristic for Vibration Isolation and Active Vibration Control Strategies
With the trend of lighter vehicle and more powerful engine (power plant) passengers are subjected to large vibration and harshness coming from the engine through the chassis. This paper discusses the application of active vibration control to reduce this vibration effect. Using a mass-spring-damper model which represents a passive engine mount, dynamic characteristic of the mount is obtained fo...
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 کاملA Study on Design of Controller Freedom Active Vibration Isolation System
INTRODUCTION Nano precision instruments with nanometer resolution are susceptible to disturbance transmitted mostly from ground vibration and mechanical vibration due to movements of the measuring instrument itself. These kinds of vibrations which are submicrometer level and low frequency distract both precision and accuracy of precision instruments. Six degree of freedom active vibration isola...
متن کاملActive vibration isolation through a Stewart platform with piezoelectric actuators
A Stewart platform with piezoelectric actuators is presented for micro-vibration isolation. The Jacobian matrix of the Stewart platform, which reveals the relationship between the position/pointing of the payload and the extensions of the struts, is derived by the kinematic analysis and modified according to measured FRFs(frequency response function). The dynamic model of the Stewart platform i...
متن کاملApplication of Compliant Mechanisms to Active Vibration Isolation Systems
Compliant mechanisms have been designed for various types of applications to transmit desired forces and motions. In this paper, we explore an application of compliant mechanisms for active vibration isolation systems. For this type of application, an actuator and a compliant mechanism are used to cancel undesired disturbance, resulting in attenuated output amplitude. An actuator provides exter...
