Specification

Aims

The course aims to cover fundamental backgrounds and technical skills about mechanics of machines, design of machines, and related core knowledge of engineering design and product development. Students will learn about kinematics and kinetics of particles and rigid bodies, as well as topics of engineering dynamics, including the effects of forces on the motion of particles, rigid bodies and vibrating systems. Students will also study and investigate about working principles, design and manufacturing aspects of the machine elements, engineering systems and products. For example; students will learn how to optimally select, design and manufacture the gears and bearings for friction reduction and energy transmission applications, and how to analyse and evaluate the kinematics, kinetics and dynamics in design and development of machines and engineering systems so that they meet well technical requirements and function effectively. State of the art topics about engineering design and product development are introduced and discussed, together with the problem-based learning case studies and group projects. Lab sections include the topics such as Drop test, Impact test, Vibration test, Analysis of machines and engineering systems, CAD, RE, RP&M, and CNC machining which are fundamental and important for students to enhance technical backgrounds and skills in engineering mechanics, design and product development.

Teaching and learning activity

The lectures are supported with comprehensive videos, demonstrations, lecture notes and presentations. Additional guides and tutorials are available for students at the end of the main contents of a course. State of the art industrial applications and case studies are used to support presentations, tutorials and in-class activities, with an online access to web-based materials, discussion forums, and training videos of software and tools. The problem-based learning group projects and lab sections are designed for students to apply the theories into the practice, as well as to develop both practical and transferable skills.
