C M.E Tran Mai Van (Lecturer) Overview about the topic As we all know, a wheel consists of a wheel rim and a tire Because this is the part that bears all the weight on the car If the wheel is of poor quality or is deformed too much due to the operation of the car, it will cause a lot of dangers on the road Severe can be very life or injury related Member: - Bach Quang Phuoc – 18146192 (Main) - Nguyen Thanh Vinh 18146257 - Nguyen Thien 18154051 - Nguyen Ho Trong Tin - CHAPTER 1: OVERVIEW Introduce of the product; Product Specifications The rim is the "outer edge of a wheel, holding the tire." It makes up the outer circular design of the wheel on which the inside edge of the tire is mounted on vehicles such as automobiles Specifications of wheel rims Criteria Iron Alloy Cost Low M - High Designs Clumsy Nice Mechanics Low M – High Allows compatibility with brake system Low M – High Maintenance Low M – High Manufacture technology Low M - High Anti-damage High L - High CHAPTER 2: DESIGN OPTIONS Design options Basic Casting - A manufacturing p rocess in which a liquid material is usually poured into a mold - The cheapest and most commonly - The density of aluminum isn’t high - Thick and heavy Press forming - Machining while the alloy is hot and solid - The product very strong and very light - The cost of equipment is also very expensive and the product is expensive CHAPTER 3: ANALYSIS, INPUT OUTPUT INPUT Input in analysis this component includes: analysis type, geometry, boundary condition and numerical parameters - Analysis system - Geometry - Material - Meshing - Boundary condition OUTPUT Output in this chapter consists of stress distribution, force convergence and deformation of the beam bracket - Total deformation - Equivalent Elastic Stress - Equivalent Stress - Fatigue Tool: + Life + Safety factors + Equivalent Alternating Stress CHAPTER 4: RESULT Member to give presentations Nguyen Thien Nguyen Ho Trong Tin CHAPTER 5: CONCLUSION Conclution Conclusion sums up what have been analysis above so as to give some information about the strain, flexibility, safety factor and its deformation In this report, many analysies have been gone through and we have come out with some conclusions below: • It’s very important to consider about the force applied on the wheels rim Because when the force is applied, it will lead to change many things such as: structural error, equivalent stress, total deformation and safety factor If everything isn’t simulated and calculated carefully, it will dangerous when we use transportation • Some problems about the wheels rim have been solved in this report Through analysis: -We know how to choose the element size in mesh and decide which one is the best for every purpose -How mesh and force impact structural error, safety factor, equivalent stress and total deformation -Which value of force can be applied to the wheels rim, and with every force, the wheels rim will change in which way THANK S!
