Final Year degree project

This Project is design a vehicle jack use for electric kart in University of Sunderland, year 2012. The objective of the jacking device design should be safe, reliable and able to raise and lower the height level of vehicle, one person can be operated by applying forces to lifting handle, the price of the material should be cheap and it should be ergonomics to human body during working. By using CES software, material selection can be selected and lab experiment (HOUNSFIELD Test Specimens) to prove the test of maximum stress of the material without bend. According to the research, this vehicle jack can be used by worldwide female as the case study is being taken on the lowest female Asian height.

The outcome of vehicle jack will be view like

The lowest chassis height to ground should not exceed to 3 inches (76.2mm) as mentioned by Technical support; George Jolley. There is 20mm clearance left between the tyre to ground surface after the kart is being lift up. This 20mm should be able for technician to change the tyre without difficulty. This vehicle jack is also being prove can be used by worldwide female. As the designer has study about female height for using this jack (Disabled World, October 2008). (that blue box is jacking point)

 

The development of a new vehicle jack is also based on materials selection charts and performance indices. Two performance indices quantifying the performance of materials regarding weight and cost have been defined and evaluated. Low alloy steels are the materials with the best suited properties. When processing possibilities, recyclability and high corrosion resistance are taken into account, steel grades turn out to be very advantageous materials.

From the vehicle jack, a student can enlarge their knowledge such as physic theory application from internet and library resources, material selection to select best material based on performance indices and CES graphs, calibration and uncertainty of calculation from auto dynamic and control module, produce best quality vehicle jack from manufacturing design and able to manage the time and project from project management and control while automotive design give advice on using engineering software and product specification to qualify the best jack product.
