DRIVELINE DEVELOPMENT

P10221

Presented by,Jeffrey Ryan

Mission Statement

To develop testing and data collection capabilities for the RIT Baja team and to help them utilize all available resources to better their competitive edge

Development Timeline

Develop – SD and Baja

Race – Baja Team

Research – SD and Graduates

Time

Project Relevance

Provides Driveline Component Knowledge to the Team

Verifies Current Designs and assumptions Utilizes the Universities Resources that

are currently Stagnant Opens the opportunities to further testing

and Data Acquisition First Step in developing more efficient

Baja Technologies. Independent of Vehicle

Staffing Requirements

Discipline Purpose

ME Test Fixture/Mechanical Design

ME Test Fixture/Mechanical Design

ME (Jeff) Integration of Mech. Sys. To Elec. Sys, Controls Development

EE Sensor and Data Acquisition Development, Controls Development

Preliminary Work Breakdown Structure

Week 1 Specific Assignments Related to gaining

understanding of team and project Read Baja Rules Read Dyno. Capabilities/Usage Read Team Values and Norm Background Discussion Tour of Dyno. Lab with Prof. DeMinco

Week 2 Begin to Assign Long Term Responsibilities

Get physical Dyno. Measurements for modeling Get measurements from Baja Component Concept generation (Brainstorming)

Required Resources

Engine Dynamometer (Department) Vehicle components (Baja Team) Sensors Material for Test Stand (Department) Software (Department)

Risks Assessment

Engine Dyno. may not be finished by end of summer

Dyno. time may be limited Baja teams Data Aq. may not be

operational Dynamic vehicle operation needs more

understanding SD would implement their own system

Baja team may be unwilling to give certain resources at strategic points in the year

Outstanding Items

Revisit QFD with Baja Team and SD Team Finish Uploading to Edge Further Understanding of Dyno. usage

and capabilities Possibly find or create some documentation
