Team 13 Design and Optimization of a Human-Powered Hydraulic Bike

This project is sponsored by:

A human powered vehicle is built every year by the Purdue Fluid Power Club to enter the National Fluid Power Association’s vehicle challenge. The team will focus on designing, building, and testing a pneumatic mechanism to engage and disengage a mechanical clutch necessary to activate the regenerative circuit of the human power vehicle. Additionally, the team will be responsible for developing a digital interface (HMI or similar) to control the functions of the vehicle and to read on-board diagnostics. The clutching system must be able to be mechanically controlled or if electrically controlled be designed to have redundancies to overcome an eventual power loss. Similarly, the electronics control needs to be robust (fault tolerant) such that loss of power or software issues does not disqualify or render the vehicle inoperable. The participating capstone team will be considered part of the fluid power club and may be eligible to participate in the race against other university teams in the spring semester. A full list of materials and components is required by December. Students will have a chance to travel at the end of the spring semester to represent Purdue and their team against other universities.

Project Details

Problem Statement

We worked in conjunction with Capstone Team 14 to design a bike that uses human power, assisted with hydraulics, for propulsion, along with pneumatic and electronic functions.
