FPN - Noise in Hydraulic Systems (formerly Module FP3)
This module builds upon the work of the FP1 and FP2 modules by concentrating on various aspects that influence the design and analysis of hydraulic systems. These include the design of valve actuator and motor systems, characteristics of proportional valves, the effect of duty cycles and load on circuit design, power economy, airborne and structure borne noise, methods for evaluating failure modes, and requirements on cleanliness and condition monitoring systems.
Who should attend
The course is suitable for professional engineers, graduates and design and development engineers. It is essential that the engineer has taken the FP2 course or has suitable knowledge of hydraulic systems and components before taking the course. A reasonable mathematical knowledge is needed.
