7Aad0054 Automotive Dynamics And Safety Assessment Answer

Question:

This Assignment assesses the following module Learning Outcomes (Take these from the module DMD)

This assignment aims to enhance students’ knowledge on theoretical modelling or applied computer simulation or other practical methods to analyse vehicles dynamics and vibration.

The successful student will be able to:

➢ Apply analysis techniques to load the suspension model

➢ Use applicable method to model quarter car model with an aim to understand:

• A method of characterizing the Newton laws for modelling oscillating behaviour

• A theoretical approach to establish calculation of a 2 degree of freedom system

• The impact of the modelling choices to the accuracy of results under different loading conditions

• Understands subtle different approaches to model a vibrating system

• How these findings can be used to improve the actual suspension system

➢ The assignment will reinforce a student to:

• Analyse oscillating structural events such as amplitude, frequencies and shape modes.

• Practice the structural behaviour under different modal assumptions (boundary conditions, load combinations)

• Understand how loads can develop through an assembled suspension.

• Be able to compare theoretical outputs to possible computer models.

• Appreciate how the simulation approach can be used to predict the structural performance.

Assignment Brief:

For the purposes of this assignment you have been tasked with simulating a simplified model of a quarter car suspension. You are encouraged to consider the identified loading scenarios and complete the tasks of this assignment. You may develop your own assumptions under your identified loading/displacement scenarios and provide a clear evaluation on the oscillating system when experiencing road conditions. Your defined assumptions should be based on a clear loading and boundary condition you may use to assess these solutions. These should lead you to develop your own model and validate it against other methods if applicable.

Please provide a report with your assumptions, calculations, solutions and observations as follows:

• Your assumptions in terms of design, requirements and measurables

• State clearly your requirements and limitations

• Justify your model choices and calculate their influence on its performance

• Explain the findings and discuss about possible weaknesses / strengths of the method

• Highlight design recommendations which can improve the function of the design.

Important notes:

• All students must submit their individual report through Canvas/Studynet.

• The mark will be awarded to individual within the Canvas/Studynet. Submission Requirements:

• Students must follow the requested tasks and report findings.

• Your submission may contain theoretical calculation, computer simulation or educational video/animation

• Applicable theoretical calculation or computer simulation must be reported using provided template.

Please see blow document for detail information.

Marks awarded for:

• The assignment contains required tasks must be reported by all students.

• Report must be completed according the instruction provided on the template.

• The marking scheme has been specified on the template of the report.

Please see blow document for detail of the tasks.

1. For undergraduate modules, a score above 40% represent a pass performance at honours level.

2. For postgraduate modules, a score of 50% or above represents a pass mark.

3. Modules may have several components of assessment and may require a pass in all elements.
