Approved March 2004 SCQF Points 15
Amended June 2017 ECTS Points 7.5

Aims of Module
To provide the student with the ability to understand, apply and discuss the modelling concepts and theories associated with free and forced vibration of 1-DOF systems and the concepts and theories associated with the dynamics of planar mechanisms, rotating machines, rigid-body and impulsive systems.

Learning Outcomes for Module
On completion of this module, students are expected to be able to:
1 Derive and solve problems involving free vibration of 1-DOF systems.
2 Evaluate forced vibration of 1-DOF systems including the concept of vibration isolation and transmissibility.
3 Apply the concept of dynamic equivalence to model vibrating systems.
4 Describe practical balancing tecchniques and analyse out-of-balance forces associated with rotating machines.
5 Analyse the dynamics of planar mechanisms.
6 Investigate experimentally the effects of spring-mass-damper on a 1-DOF vibration system.

Indicative Module Content
Kinematics of planar mechanisms with revolute (pin) and prismatic (sliding joint); forces and torques arising in planar mechanisms owing to inertia forces and moments associated with acceleration of links. Free vibration of undamped 1-DOF systems. Dynamic equivalence of engineering systems. Free and forced vibration of damped 1-DOF systems. Transient response to simple inputs. Steady-state sinusoidal response. Vibration isolation and forces transmitted to supports. Impulse force, impact and momentum. Kinetic and potential energy. Balancing of rigid rotors. Single plane and two-plane balancing.

Module Delivery
This module is lecture based with tutorials, directed self-study, laboratory work and private study.
