Über dieses Buch

This book discusses efforts to control the low-frequency vibration transmission of typical power equipment and pipeline systems of ships, exploring the use of active and passive hybrid vibration isolation and adjustable dynamic vibration absorption technologies. It also proposes an adaptive feed-forward control strategy and studies a distributed feed-forward control hardware system. In addition, the book presents a three-way dynamic vibration absorption theory used to design a pipeline-system adjustable dynamic vibration absorber, which offers a number of advantages, such as compact structure, easy assembly and disassembly, low power consumption, excellent vibration control effect and wide frequency band adjustable ability, etc. This book is a valuable resource for researchers and engineers in the fields of noise and vibration control, active control systems, active vibration isolation and adaptive dynamic vibration absorption.

Chapter 2. Active and Passive Hybrid Vibration Isolation
Abstract
In this chapter, based on the Halbach magnetic array, the active and passive hybrid vibration isolation technology for WD618 diesel engine is studied. Firstly, the active and passive hybrid vibration isolators based on Halbach magnetic array is designed. The content includes design requirements, scheme design, and design method; design suitable power amplifier for isolators and verify whether the performance index requirements are met and test the resistance, inductance, stiffness, and static thrust of isolators; the vibration isolation effect of the vibration isolator was tested through a single-degree-of-freedom vibration isolation experiment.

Chapter 3. Active and Passive Hybrid Vibration Isolator Performance Test
Abstract
In this chapter, the following objectives are tested for the performance of the designed active–passive hybrid vibration isolator:
  • Test spring stiffness, electromagnetic force to verify compliance with design requirements;
  • Test whether insulation resistance meets the need for safe operation;
  • Test resistance and inductance to design suitable power amplification equipment.
Furthermore, the active and passive vibration isolation performance of active-passive vibration isolator for single-frequency excitation will be tested.

Chapter 4. Adaptive Feed-Forward Control System
Abstract
This chapter designs and implements the active and passive hybrid vibration isolation control system. The complete active control system includes software and hardware. The software mainly refers to the control strategy and control algorithm implemented in code form. The hardware includes sensors, actuators, power amplifiers, and controllers. This chapter is based on the vibration characteristics and vibration transmission control characteristics of the WD618 marine diesel engine. The hardware design of the active control system includes a controller and a digital power amplifier that satisfies the power requirements of the active and passive hybrid isolator.

Chapter 5. Comprehensive Experimental Verification for AVI
Abstract
This chapter studies the application technology of active and passive hybrid vibration isolation. The active and passive hybrid vibration isolator designed in Chap. 2 and the active control system designed in Chap. 3 are applied to the control of diesel low frequency vibration transmission. Firstly, the vibration characteristics of diesel engine under typical installation environment and the influence of diesel engine noise on base vibration are analyzed. Based on passive vibration isolation performance test, active control is started to test the effect of active and passive combined control of low frequency vibration transmission under typical operating conditions.
