Notes to all students wishing to take this class but couldn’t do so, please write an email to me explaining why you would not get a degree without taking this course (with proof of your academic record according to your major requirement), and then file your application with SUSTech to add a seat for your self. We will decide later, based on your case, whether you will be added to the class or not.

Student Groups

Due to the sudden increase in students, we have to split the class into two groups for the lab session, where the students in each group will take turns to do the lab experiments and group discussions.

Instructor Team

Course Objectives

  • This course is intended for students beginning the professional study of mechanical engineering. The focus is on combining fundamental concept development with a practical specification of mechanical components. Subjects covered by this course include engineering basics, failure prevention, gear components, joint components, flexible components, and various other mechanical components. Special topics will be covered regarding the pathway from mechanical engineering fundamentals towards future directions of the design engineer in research and industry towards advanced machinery, automation, and robotics.
    • To teach students how to formulate the design and manufacturing problem for mechanical systems.
    • To teach students how to apply the general mechanical engineering sciences in analyses specific to the design of mechanical components.
    • To teach students in a laboratory setting how to generate concepts, conduct analyses to size components, construct, assemble, and program a prototype of a system and test its function to meet the specifications of a design and manufacturing problem.
    • To reinforce students’ team skills through a team project, including problem formulation, problem solutions and written reporting of results.
    • To reinforce students’ visualization and hands­-on skills through project virtual prototyping and/or physical construction exercises.

Learning Outcomes

  • As a core course for a mechanical engineering major, this course lays the foundation for students to conduct machine design, manufacturing, and related research and development. The following learning outcomes are expected for students taking this course:
    • Given functional and manufacturing requirements, utilize concept generation methods within a team setting to achieve a consensus for a product concept.
    • Weigh trade-offs in concept and detail design from the perspectives of function, manufacture, design effort and available resources.
    • Apply the basics of conservation and constitutive laws from the mechanical engineering sciences to understand the basic nature of a posed problem.
    • Compile reference (e.g. catalog, handbook, and textbook) resources to formulate an analysis for specific mechanical and mechatronic components addressed within those resources.
    • Make decisions regarding buying or building for individual components of a design.
    • Test, in a team, setting or independently, the system performance and all failure modes that may be present per the analyses conducted during the design stage.
    • Communicate engineering decisions, the justification for those decisions, designs, manufacturing plans, and test results in multi-media presentation and report writing.

Design Engineering Project

  • 4 teams of students will be formed to work on a Design Engineering Project.
  • The goal of this project is to design and fabricate a manual linear line engraving device to mark a straight line of randomly selected length on an aluminum block with the highest precision and quality within 200 RMB budget.
  • The device must be fabricated from a block of raw material according to the engineering design provided by each team.
    • All designs must be provided with a full set of engineering drawings and approved by me before proceeding to actual fabrication.
    • The students can fabricate this device by themselves using any available tools and machines from the department and must register with the TA before doing so.
    • The students can also send their drawings to a professional service provider, but the cost will be included in their final budget as well and must register with the TA before doing so.
    • The students can not use any commercial linear parts to build their devices.
    • Any mechanism is welcome, as long as they can engrave a high quality and precision line on an aluminum block.
  • The final assessment of their results will be scientifically tested by a professional measurement device from a professor’s lab, which will be unveiled in the final class.

Final Week Presentation

  • We will host a mini competition in the final week’s class and there will be prizes.
    • Before class starts, you will need to submit your final report electronically at this link (to be provided later).
    • Each team will prepare a poster to showcase your design and fine-tune your prototype.
    • Then, we will have a competition to see which team’s design can produce the most accurate measurement.
    • Selected teams will be invited to give a 5-min Video Presentation of their design, followed by a quick Q&A.
    • Your markings for this session will be based on your competition results~
  • Here are the things you will need before coming the final week’s class
    • A Prototype fully designed and built by you, preferably a working one
    • A Poster describing the key features of your design and device
    • A 5-min Video describing the technical details of your design
    • A 5-page Report describing the technical details of your design
    • And all your team members.

How to Video Record Your Presentation using PowerPoint

There is a simple solution in Microsoft PowerPoint, as a recording function is built-in the software.

  • The content of the video should revolve your presentation, but you are welcome to be creative about how to present it.
  • This is a Team assignment, and the question about who to present makes no sense at all.
  • You need to prepare and submit a PDF version of the slides.

Late Homework Policy

  • Each student is granted four unpenalized late days for the semester. Homework can be handed in no more than four days late and will receive a 25% penalty for each day late (excluding unpenalized late days used). Homework is due at 3 PM on the due date, and each late day extends the deadline by exactly 24 hours. All homework must be done to pass the course.

Course Materials

  • Required: Shigley’s Mechanical Engineering Design (McGraw-Hill Series in Mechanical Engineering) 10th Edition by Richard G Budynas (Author), Keith J Nisbett (Author)
    • Limited reprinted copies can be borrowed from the TA.
  • Optional: Machine Design (5th Edition) by Robert L. Norton (Author)

Academic Integrity

  • This course follows the SUSTech Code of Academic Integrity. Each student in this course is expected to abide by the SUSTech Code of Academic Integrity. Any work submitted by a student in this course for academic credit will be the student’s own work. Violations of the rules (e.g., cheating, copying, non-approved collaborations) will not be tolerated.
