MECH4240 Spring 2012 Professor Beale 3418C Wiggins 334 844 3336 bealedg auburn edu Office Hours MWF 11 12 and by Appointment Teaching Assistant David Branscomb ABET Objectives The Program Outcomes for the Mechanical Engineering Undergraduate degree are as follows Graduates will have a an ability to apply knowledge of mathematics science and engineering b an ability to design and conduct experiments as well as to analyze and interpret data c an ability to design a system component or process to meet desired needs within realistic constraints such as economic environmental social political ethical health and safety manufacturability and sustainability d an ability to function on multidisciplinary teams e an ability to identify formulate and solve engineering problems f an understanding of professional and ethical responsibility g an ability to communicate effectively h the broad education necessary to understand the impact of engineering solutions in a global economic environmental and societal context i a recognition of the need for and an ability to engage in life long learning j a knowledge of contemporary issues k an ability to use the techniques skills and modern engineering tools necessary for engineering practice p1 an ability to apply principles of engineering basic science and mathematics including multivariate calculus and differential equations to model analyze design and realize physical systems components or processes p2 an ability to work professionally in both thermal and mechanical systems areas A Structured Design Approach The Design Space Pathway The Vee Chart There are two kinds of designs in this course An architectural design or architecture and An architecture reveals the subsystems and their interfaces and engineering specifications for each with requirements that are fed to subsystem engineering design teams It is a big picture design detailed design which includes fully dimensioned CAD drawings created by subsystem engineering teams

Examples of Architectures Architectural Design of a Lunar Base LUNOX Outpost Like NASA s First Lunar Outpost study LUNOX would only employ expendable spacecraft and rockets although the lunar surface infrastructure is reused The first mission would deliver enough consumables for a 2 crew 14 day mission to accomplish setup repair or maintenance of the surface infrastructure Future 4 crew missions of up to 45 days would also be feasible although the required supplies crew consumables experiments liquid hydrogen for the LUNOX system and fuel cells must be delivered by a separate unmanned cargo flight Figure 12 Product hierarchy through tier 3 orbiter avionics system only also from Phase A CubeSat Architecture The Key Contributors Who Impact the Process Sponsor The primary stakeholder Technical Advisor Assists the team Monitors progress Overlord Assures that accreditation objectives are being met Usually a contributor is a single person Sometimes the same person can serve as more than one contributor Sometimes two people can work together and serve as a single contributor Expect all three contributors to be present at your midterm and final presentations in MECH4240 Sponsor Involvement The Sponsor is the Primary Stakeholder i e the person who has the most interest in the success of the project Duties of the Industrial Sponsor Evaluates i e grades the technical content and product at midterm and final presentations The grade is conveyed to the technical advisor to give to the team Sometimes the Sponsor will effect the design direction if the project does not appear to be meeting their objectives Establishes the need which begins the design process Pays for the project Often the Sponsor is a very experienced engineer who KNOWS what is needed from your design and product Technical Advisor Involvement Monitors your progress and meets with the group biweekly or as needed or requested by the team Grades design notebook Manages and may contribute to peer reviews Serves like a senior engineer i e someone who has had previous design experience can answer some technical questions or else guide the student team toward resources to get their questions answered In some situations the technical advisor may assign task s so that the student s answer their own question Breaks down walls impediments to progress when a team or student is stuck The Technical Advisor does not lead the team s design effort or make assignments that is the duty of the team manager May offer design suggestions but should not be the source of design innovation The technical advisor allows students to explore their own creative ideas and to perhaps fail should those ideas not pan out i e a successful failure However if the student team is not proceeding with a workable solution or is off on a tangent the technical advisor may intercede and redirect the effort Overlord Involvement The Overlord makes sure that the ABET Accreditation Board for Engineering and Technology objectives are being met This is primarily achieved by midterm and final reports that follow a specified format and is a well written technical document The Overlord will grade your midterm and final reports and also individual student presentations Other People Vicki Nelms is the administrative assistant who is responsible for billing and Purchase Orders see technical advisor when ready to order
