REFERRAL ASSIGNMENT 2 of 3

EAT 216

COMPUTER AIDED ENGINEERING

STRUCTURAL ANALYSIS BY COMPUTER AIDED ENGINEERING METHOD USING FEA APPLICATION

This is an individual assignment, it contributes 25% of the total marks for the module. Answer all answers.

The submission shall be in the form of a technical report which will contain sufficient details for the reader to understand your 3D modelling and all the boundary conditions that you have used in the simulation.

The report must include all relevant structural parameters outputs & contours to show the design is safe & satisfactory.

Students are advised to avoid plagiarism. Such an act can cause students to fail.

Duration of this assignment is 10 weeks. Students are advised to submit final report on submission date. In case of late submission, marks will be deducted.

Refer to the attached the project brief for assignment for detail.

Design an engine crane/hoist as similar to crane shown in Figure 1 below. The design must consist of all the elements, components and parts as in Figure 1 below. Design of the structure is crucial in order to withstand the weight of the engine.

Other specification are as follow;

1)      Total length to be less than 1.5m

2)      Total height to be between 1.9m to 2.0m

3)      Boom can extend about 2.0m in total

4)      Able to lift engine ranging from 2.0L to 3.0L engine capacity
