Traditionally, fluid power systems are designed by considering various factors such as function, performance, reliability, safety, product cost, etc. Due to increasing awareness of energy use in industrial processes and their effect on the environment, energy costs are becoming an important criterion in the design of such industrial products. Analytical methods that determine energy loss in hydraulic systems are currently complex and computationally inefficient.

Experimental methods can be used to model energy efficiency in systems and study the performance of individual components. This paper presents the instrumentation required for monitoring process parameters of a hydraulic system in a senior design project. Though the focus of the project is to design an energy efficient system, such instrumentation allows for the use of experimental analysis in the design process and allows students to complete the design according to the timeline of the project.

A prototype of the system is being developed in the laboratory, as is virtual instrumentation based on the National Instrument data acquisition system. Individual process sensors are used to acquire process data. A LabVIEW program processes the sensor signals and creates a data file. The data is imported in an external analysis tool (MatLab) for determining parameter sensitivity and the system’s overall energy efficiency. Optimization of the cost function determines the optimal process parameters in the design.

Implementation of the parameter values in the physical system will result in an improved design of the hydraulic system and establish the validity of both the instrumentation and experimental method used in the design process.
