Abstract   (7 Mark)

A concise and factual abstract is required. The Abstract should be informative and completely self-explanatory, briefly present the topic, state the scope of the modelling, indicate significant data, and point out major findings and conclusions. Abstract may present separately from the article, so it must be able to stand alone. For this reason, standard nomenclature should be used, and abbreviations and references should be avoided. Font size 11 or 12 Arial or Calibri and 1.15 line spacing is suggested. The word limit is 100 (+/- 20%) words. Wordcount must be inserted separately for all section.

Wordcount: 95

 

Problem description   (8 Mark)

In this section you should provide a detailed description of the problem under investigation. Subsequently, this should include a schematic of the model, plus a description and justification of the boundary conditions used. Only those material with direct link to the problem should be inserted here. Please AVOID presenting general materials or copy/past from assignment brief or other sources. You are encouraged to describe the problem using your own words. Please make sure to cite respectfully those materials collected from others. References should be in Harvard or APA formats (see the Guidance on Studynet). Word limit is 100 words (+/- 20%). Please note that if work exceeds the +10% tolerance on wordcount, marking will be stop at that point.

Wordcount: 119

 

Methods on proposed solution  (total 60 Marks)

In this section, you should provide details on following tasks as appreciated. You need to produce enough evidence confirming the convergence of any theoretical calculation with computer simulation. Word limit for this section is maximum 300 (+/- 70%) words. Please don’t forget to answer any TWO tasks out of THREE following tasks.

 

Task 1: Theoretical modelling (30 Marks)

a)   Perform free body diagram (FBD) of the system in full detail 

b)   Deliver equation of motions (EOM) contain all components of system in parametric form

c)   Find natural frequencies of the system when individual data applied

d)   Find the responses of the system, general form must be derived using individual data

 

Task 2: MATLAB simulation (30 Marks)

a)   Create a MATLAB program  

b)   Find natural frequencies of the system and compare those with Task 1

c)   Simulate the system on specified road profile

d)   Redesign the suspicion system and create new parameters

 

Task 3: Educational video (30 Marks)

a)  Create a video to show the stages of Task 1 solution  

b)   The video must address all criteria specified in the Assignment Brief

 

Total wordcount: 163 (excluding MATLAB code and equations)

 

Discussion on result, recommendations, conclusion  (20 Marks)

In this section, you should discuss on results obtained from modelling and simulation. Comparison of the result and discussion on differences is expected in detail if applicable. You may need to produce enough evidence to confirm the validation of the theoretical model and computer simulation. You may need to provide recommendations the design and suggestion on justification of input data. You may suggest how the design can be improved to obtain a higher performance and quality for the suspension. Finally, A conclusion must summarize of the main findings of the presented work. The concluding remarks of the study must be clearly presented. Word limit for this section is maximum 200 (+/- 50%) words. The concluding remark must wrap up the entire purpose of the report in a single paragraph.
