Agenda Background Open Items from Last Review Problem Statement Customer Requirements Engineering Requirements Systems Design Concept Development Engineering Analysis Risk Assessment

Open Items From Last Review Refine Risk Assessment Develop modules on experimental and analytical levels

Problem Statement & Deliverables Current State Students in the Mechanical Engineering department currently take a sequence of experimental courses, one of which is MECE – 301 Engineering Applications Lab. Desired State Three to four modules used to provide a set of advanced investigative scenarios that will be simulated by theoretical and/or computational methods. Project Goals Create modules to instruct engineering students Expose students to unfamiliar engineering ideas Constraints Stay within budget

Customers & Stakeholders Professor John Wellin Contact: Professor Ed Hanzlik Contact: Engineering Professors and Faculty Engineering Students MSD Team

Customer Requirements Requests 3 modules at minimum; 4 or 5 are preferred Modules may be of different technical challenge and complexity All modules must emphasize practical engineering experiences Each module should be interesting to the students Modules should bridge applications areas, such as electromechanical or electrochemical All modules should use commercially-off-the-shelf equipment to enable maintenance and sustainability of module use over many semesters of student enjoyment All module should have analysis challenges that are at or beyond student learning from core coursework

Customer Requirements Continued All modules should be able to: Fully configured, utilized, and returned by student engineers Stand alone; contain everything they need without borrowing from other sources Have a high level of flexibility and expansion allowing for many engineering opportunities Be robust and safe

MSD team interest CN8 3 Can be run by 1 student but can be up to 3- 4 students -Determine number of tasks and complexity required for each module -Personal experience from MSDI Team will be considered CN9 1 Modules can use commercially-off-the-shelf equipment to enable maintenance and sustainability of module use over many semesters of student enjoyment. Research and define what can be built by the MSDI Team verses what can be bought out of the total number of parts required for the module CN10 3 All modules should be stand alone; they should contain everything they need without borrowing from other sources. Test modules in lab setting CN11 3 All modules must be robust and safe.Conduct testing on equipment and modules CN12 3 All modules should able to be fully configured, utilized, and returned by student engineers. Conduct testing on equipment and modules CN13 3 Design and build an experimental apparatus equipped with appropriate measurement tools Define measurement tools required for each module- (1) hardware (ie- controller boards, motors...) (2) Software (labview, matlab, transducer specific programs)
