Module: Mechanical Engineering System Simulation

Module Specifications.

Current Academic Year 2024 - 2025

All Module information is indicative, and this portal is an interim interface pending the full upgrade of Coursebuilder and subsequent integration to the new DCU Student Information System (DCU Key).

As such, this is a point in time view of data which will be refreshed periodically. Some fields/data may not yet be available pending the completion of the full Coursebuilder upgrade and integration project. We will post status updates as they become available. Thank you for your patience and understanding.

Description

Analysis and modelling of two degree-of-freedom vibrating systems. Matrix representations of multi-dof systems. Free and Forced response calculation. Vibration of continuous systems - calculation of modal frequencies and shapes dependent on boundary conditions and wave equation. Forced vibration of continuous systems. Introduction to computer based simulation of mechanical engineering systems and use of commercial & development packages for simulation. Simulation of mechanical systems and components including machine elements, electrical and electro-mechanical systems, thermal systems, and hydraulic systems. State-variable modelling and techniques for validation of models.

Learning Outcomes

1. Analyse 2 DoF vibrating systems for modal frequencies and shapes and response to harmonic excitation
2. Determine the wave equation for 2nd & 4th order systems and apply boundary conditions to define mode shapes. Perform modal and forced-vibration analyses of simple continuous systems.
3. Develop modelling strategies for multiple DoF simulation
4. Formulate a State variable model of mechanical and other systems
5. Build dynamic models in Xcos and apply parameters through Scilab. Analyse and present output results.

Reassessment Requirement Type
Resit arrangements are explained by the following categories: Resit category 1: A resit is available for both* components of the module. Resit category 2: No resit is available for a 100% continuous assessment module. Resit category 3: No resit is available for the continuous assessment component where there is a continuous assessment and examination element.
* ‘Both’ is used in the context of the module having a Continuous Assessment/Examination split; where the module is 100% continuous assessment, there will also be a resit of the assessment
This module is category 1
