Design and simulation of fatigue analysis for a vehicle suspension system (VSS) and its effect on global warming

摘要

Research shows that for every gallon of gasoline burnt, 12.7kg of CO2 is released. Fuel economy improvement is almost linear with a reduction in weight of a car. Therefore, reducing vehicle weight results in less fuel consumption and a decrease in CO2 emission which in turn has an effect on global warming. Car manufacturers are facing increasingly stringent CO2 emission standard. In this project, an investigation was carried out on vehicle suspension system (VSS) by employing Finite Element Analysis (FEA) to analyze the fatigue life, von misses stress, factor of safety and stability of the suspension system and how the weight and size can be reduced. Solidworks14~R was employed to analyze different materials used in the design and development of VSS; comparison amongst the various materials used was carried out to inform that there can be reduction in the size and weight of the four suspension system by using Titanium Ti-13V-l lCr-3Al Treated, which will drastically reduce the weight of the car and give better result of strength and durability, ultimately reducing CO2 emission and its negative effect on the climate. This innovative design-can be introduced as a reference for the automotive industry.
