Abstract

Human powered energy efficient vehicle designRecent awareness in energy consumption and environment has generated interest in ecofriendlytransportation system in both developed and developing regions of the world. Government andprivate sectors are encouraging innovative development and use of energy efficient vehicles fortransportation of people and goods. Design and development of such systems is a popular designissue in both academia and industry. In this paper, an industry sponsored student project fordesign and development of a human powered transportation system is presented. It allows asingle rider to move in all types of terrain by transferring power to the drive train through the useof a biodegradable hydraulic fluid. Besides the design criteria specified by the project sponsor,functionality, safety and reliability, manufacturability, and cost effectiveness are focus of thisdesign process. Overall design objective is to minimize the weight and maximize energyefficiency of the low power hydraulic drive train. Among the innovative human poweredtransportation ideas, a system utilizing a three wheeled recumbent style tubular aluminum frameis adapted. It optimizes rider comfort, weight and provides support of all hydraulic componentsand drive train. The pedal power of the rider runs a modified bent axis fixed displacementindustrial pump and transfers pressurized fluid to a hydraulic motor of similar classification. Apressure sensing hydraulic circuit allows storage of the pressurized fluid in a hydraulicaccumulator and releases the fluid on demand such as during the uphill motion. A light weightmechanical drive train provides appropriate torque to drive the pump and driving wheel under alldriving conditions. In the spring of 2012 the system will participate in a national designcompetition among twelve engineering schools. The designs will be evaluated based onestablished design objectives and performance of the system in a 100 m sprint race and 12 mileendurance race.
