The Development of a Hydraulic Hybrid Vehicle Laboratory: Integrating Education and Research


This paper presents the development of a new hydraulic hybrid vehicle based laboratory course for the Mechanical, Industrial, and Manufacturing Engineering Department at the University of Toledo. The objective of this new laboratory course is to serve as both an educative tool for undergraduate students as well as a tool in advancing the research of hydraulic hybrid vehicle technology. The educative module is based on a problem-solving learning approach that will aid students in gaining a richer understanding of elements from courses of the Mechanical Engineering curriculum such as Fluid Dynamics and Hydraulics, Energy Systems, Vibrations, Mechatronics and Controls. Additionally, the modules developed for the hydraulic hybrid system will become available on the internet for other universities to utilize. The laboratory will also serve as a research tool for the advancement of hydraulic hybrid vehicle technology. To this end, both graduate and undergraduate students will be performing experiments and simulations that will enhance understanding of hydraulic hybrid systems. The knowledge obtained will be utilized to aid in optimizing the design of hydraulic hybrid vehicle technologies.


Hydraulic hybrid vehicle technology is an interesting and expanding focus area for researchers concerned with alternative fuels and greener solutions to emissions problems. The hydraulic hybrid concept employs many aspects of engineering fundamentals and therefore, can provide for a convenient means of integrating engineering fundamentals into an application based learning experience. Application of hydraulic hybrid vehicle technology specifically requires knowledge of thermodynamics, fluid dynamics, kinematics, controls and vibrations and acoustics. These subjects however, oftentimes can be very arduous for a student. This is because it is difficult to provide a solid mass of the subject, i.e. something to actually look at and study. The aim of the laboratory herein is to integrate fundamental engineering curriculum in such a way as to provide a hands on application to study the principles at work. The hydraulic hybrid vehicle technology is such an application that can be utilized to study engineering principles.

Additionally, the course shall be offered as both an undergraduate and graduate course. The course will incorporate not only a hands-on problem-solving learning approach, but will also utilize and encourage basic research tools. The course is designed such that the students will perform a research review and assemble a paper that provides a basic survey of current research areas in the field of hydraulic hybrid vehicle technology. This way, the course provides an opportunity for undergraduate students to gain experience in basic research tools and expose them to the kind of work a graduate student is expected to perform. Also, beginning and advanced graduate students can refine and expand their experience performing research-based work. Finally, students will have the opportunity to expand and improve upon basic and advanced communication skills via laboratory interaction and written and oral presentations of work. It is expected that each student can produce a conference publication from their work.
