Abstract

The main objective of this project is design of car hood lifting mechanism using sensitive hydraulic system. Firstly, the Proton Saga is selected as vehicle model for this project. Usually, the Proton Saga users need to open their car hood manually. It is required few steps to open the car hood. Therefore, it is a hassle for the users in the opening process of car hood as it requires a few steps. So, the sensitive hydraulic system is used to design car hood lifting mechanism to overcome this problem. The sensitive hydraulic system means that the hydraulic piston needs withdraws with small distance in order to lift the car hood exponentially. The sensitive hydraulic system is focused in this project because it can prevents the larger size of hydraulic cylinder to be used. Several approaches are used for conducting this project successfully. First of all, first survey is conducted to acquire some feedback. Five hand sketching design concepts are drawn and then Pugh Matrix method is used for concept selection. 3 Dimensional Computer Aided Design (3D CAD) of the selected design concepts are drawn using Computer Aided Design. Motion analysis and finite element analysis are performed to select the best design concept. Displacement can be obtained from motion analysis. Finite element analysis can test whether the components able sustain the load. Hence, the simulation results are compared to select the best design concept. Concept 2 is selected as the best concept design because it proves that it only requires shortest displacement of piston which is 50 mm. Besides that, concept 2 achieves highest factor of safety which is 5.36201 compared to other design concepts. Lastly, the second survey is conducted for concept validation. Second survey will be the last step for this project.
