SUBMISSION DATE AND TIME: 14th April 2024 – 23:59 or any time before. INSTRUCTIONS 1. The assignment should be your own original work and should be properly type-written in your own words. It will be checked for plagiarism using Turnitin. Any plagiarism or copying from others will be dealt through the university’s plagiarism procedures. Similarity (plagiarism) level higher than 10% is highly suspicious. 2. The whole report should be 1500 words plus any relevant material. Any references to materials should be given in standard Harvard or Vancouver form. 3. Your assignment must be submitted electronically via blackboard by the submission time or before. The report should be contained in a Word document or pdf document. No other means of submission will be accepted. 4. Drawings can be done by hand or electronically. They can either be scanned / copied into your Word or pdf document. 5. Any assignment submitted late, but within 5 working days of the deadline, will be given a maximum mark of 50%. Assignments submitted more than 5 working days after the deadline will not be marked, and a mark of 0% will be recorded. 6. Students with special needs will be addressed on individual basis. (Candidates that may require any special requirement will be dealt with on a one-on-one basis which must be discussed with the module tutor/lead before the due date). Learning Outcome to be assessed: This assignment is structured that students show evidence for partial fulfilment of the following module learning outcomes 1. Analyse and predict the statistical behaviour of machine failures. 2. Discuss the typical causes of failures in machines, analyse failed systems and identify the causes of failure. 3. Develop equations of liquid film lubrication, and apply them to typical industrial bearings. 4. Synthesise designs of dry and lubricated bearings using an understanding of the fundamental operating principles, and aided by computerised design guides. 5. Describe the most common condition-monitoring systems, and evaluate their reliability for specific situations.

Page 6 of 9 ASSIGNMENT ROHM Semiconductor Automotive Solutions Limited is planning to introduce a new model to address urban transportation challenge by investing in the emerging mobility service with the generation of cleaner vehicles and sustainable urban logistics. You have been asked to design and analyse the reliability of this new electric car system. https://www.youtube.com/watch?v=0jXnHeH9GNg https://www.youtube.com/watch?v=K4JhruinbWc This is an open assignment, the result and data of the car component is not known. ASSIGNMENT OBJECTIVES: To understand the history of automobiles and the methodologies to analyse the automobile systems. To construct a reliability block diagram (RBD) analysis for the simplified new electric car system model. To perform failure mode effects analysis (FMEA) for the same electric car system model. To do a fault tree analysis (FTA) on the same electric car system model. To propose measures to prevent the system/ sub-systems failure, and compare the difference among the RBD, FMEA and FTA. Page 7 of 9 ASSIGNMENT BRIEF: As an engineer in the ‘ROHM Semiconductor Automotive Solutions Limited’, you have been asked to perform reliability analysis on the electric car system. To be specific, by using reliability block diagram (RBD), failure mode effects analysis (FMEA) and fault tree analysis (FTA) to analysis the model. Additionally, you should propose measures to prevent the system/ sub-systems failure, and compare the differences among the three methodologies. Provide a detailed, professional report that contains the following items mentioned below: 1. Illustrate the history of automobiles and the methodologies to analyse the automobile systems. Hint1: You should use the online resources (papers, reports, books) to illustrate this in the introduction part. Do not forget to use references. 2. Look through different online resources to find the failure data for various components of the electric car system model. Construct a reliability block diagram (RBD) analysis for the simplified model. List out all the assumptions you have made in the construction of the RBD (e.g. failure criteria, failure/repair interval, maintenance strategy, etc.) Hint2: Websites mentioned below could be useful however you should also search for more specific data and put your findings in a table with references cited. http://reliabilityanalyticstoolkit.appspot.com/mechanical_reliability_data 3. Perform the Failure Mode Effects Analysis (FMEA) on the electric car system model. Hint3: Review the FMEA method and perform the FMEA analysis on the bearing. FMEA data can be got through questionnaire or based on your own reasonable assumptions. You should use the FMEA worksheet to explain your work. 4. Construct your own fault tree and do a Fault Tree Analysis (FTA) on the electric car system model. Hint4: You should consider the events that will cause the electric car failure, and construct the fault tree by using AND/OR logic gates. Make your own assumption for the events failure rate, and calculate the failure rate of Top event (electric car failure). Page 8 of 9 5. Discuss and propose measures to prevent the system/ sub-systems failure, compare the differences among RBD, FMEA and FTA. Hint5: In the discussion part, you should specify what measures you want to use the mitigate the risks. And illustrate the differences among these three methodologies based on your own calculations.
