Vehicles need to have regular maintenance and repair so that hoods need to be easy to opened and closed. With the addition of more women car owners, this requirement that automobile hoods requiring lower opening and closing efforts become even more important. This research looks into vehicle engine hood mechanisms that incorporate a pin go to assist in the opening of the hood. The design of such mechanisms as divided into two steps. The first is carried out using three position synthesis. In the second step, different types of springs such as extension, compression and torsion springs are applied and optimization procedures is used to determine the various location for the springs and the spring parameters to minimize the effort to raise the hood. A sensitivity analysis is also carried out on the best of the three spring types and configurations to determine its suitability for practical implementation.
