Overview

In this unit, you will explore how and why mechanical and structural systems vibrate, and how vibration influences performance, safety, and reliability. You will analyse real and simulated vibration responses using analytical, computational, and experimental techniques, developing a deep understanding of how dynamic behaviour shapes modern engineering design.



Through authentic measurement, signal processing, and modelling activities, you will integrate theory with practice to evaluate and manage system performance under dynamic conditions. The unit emphasises precision, creativity, and problem-solving through hands-on experimentation and data-driven analysis, preparing you to design safer, more efficient, and resilient engineering systems.

Learning Outcomes

On successful completion of this unit, students will be able to:

  1. Apply and justify mechanical vibration principles in the design and evaluation of engineering systems;
  2. Measure and evaluate vibration characteristics in mechanical systems, assessing safety, performance, and sustainability implications;
  3. Construct and validate numerical models of vibratory systems to predict and enhance mechanical performance;
  4. Apply multi-channel frequency-domain methods to analyse and interpret vibration data from physical and digital systems; and
  5. Collaborate effectively to produce clear, evidence-based reports for diverse technical and non-technical audiences.

Exercise: This secure in-class assessment ensures authenticity by requiring students to analyse and interpret unseen vibration data under supervised conditions. Real-time problem-solving and unpredictable scenarios verify student understanding of system dynamics and signal behaviour.

Laboratory Work: Experimental investigation involving measurement, modelling, and evaluation of vibratory systems. Students collect and analyse vibration data, develop models, and interpret frequency-domain results within collaborative teams.

Test: This secure invigilated test ensures authenticity by requiring students to apply vibration theory, data interpretation, and computational analysis to unseen scenarios. Unpredictable problems confirm independent reasoning and professional competence.
