This book focuses on hydraulic components and machines, and illustrates how a machine's noise-radiating surfaces affect noise. It reviews the basics and terminology of sound, vibration, vibration isolation, fluid pulsations, Fourier analysis, cavitation, hydraulic shock, and enclosure design.

Hydraulic systems are used on marine vehicles for steering, vehicle control, and utility services. System components that generate and transmit noise are of concern. This SAE Information Report (a) addresses noise requirements which may apply to the hydraulic systems of ships and submersibles, and (b) identifies noise sources and techniques which may be used to reduce system noise. Noise of power sources (e.g., electric motors) and end items (e.g., steering linkages) is beyond the scope of this document.

A preliminary investigation of noise in hydraulic systems was undertaken in order to determine causes and methods for reduction of noise. A method for predicting the sound pressure level associated with fluid pumping was achieved. Predictions made by this method agreed with experimental measurements made on a representative hydraulic system developed for this research. It is recommended that the calculation method be extended to include all types of pumps and piping arrangements found in hydraulic systems and that the experimental apparatus be modified to further test predicted results.

This practical handbook examines in detail the measurement, isolation and treatment of noise and vibration problems. Based on practical industrial experience of leading consultants in the field the book features comprehensive coverage of legal, medical and scientific background, examines noise problems of a whole range of industrial plants, gives full details of the treatment of noise problems and the avoidance through design, planning and maintenance and is extensively illustrated with a full bibliography.

The excitement and the glitz of mechatronics has shifted the engineering community's attention away from fluid power systems in recent years. However, fluid power still remains advantageous in many applications compared to electrical or mechanical power transmission methods. Designers are left with few practical resources to help in the design and
