Crash Analysis Calculation/report

Figure 1 illustrates a simple vehicle. Assume that the mass of the vehicle is 1600Kg and the speed of hitting a wall is equal to 64Kph (Figure 4) Design a crash structure (Figure 4) according to your engineering choices. The design of the crash structure gauges, lengths and materials and the entire emerged outcome (performance, weight, cost) are free for you to develop. However you need to abide to a good crash performance for the overall deceleration crash case. Key parameters and proportions need be explained and justified adequately. Assuming occupant has the same decelerations with the vehicle consider deceleration limits according to the Human Tolerance & Survivability Guide. Key calculations and assumptions need be explained and justified adequately. Report Overview The report should comply to the following structure; 1. Introduction and Problem Formulation: Description and explanation of the basic material properties and basic physics expected. 2. Methodology: Overview of the solution used; detailed assumptions and calculations such as; material definition, basic material characterisation and related curves used, assumptions of the overall calculations / spreadsheets used. Finally how the calculation was developed. 3. Results and Analysis: Initial Energies, Energy / Force / Velocity / Displacement study (spreadsheet calculations); Energy / Force / Velocity / Displacement path description; Final Intrusion and Injury Calculations, Compare the results with the human tolerance and survivability limits.. 4. Conclusions: Conclusions and recommendations. Which areas remained on the elastic and which reached the plastic? Cheapest Vs Lightest Vs Safest what were the tradeoffs and why?
