Abstract

Nowadays, automotive industry is focusing more on lightweight vehicle because the weight of the vehicle can affect efficiency of the car itself. Therefore, to improve the weight of the car, it is a good idea to design a vehicle, which is high efficiency and lightweight by doing the research on material of existing car so that other material could be used to replace the existing material. Besides that, the structure of the car can be change so that it can achieve the target of lightweight vehicle. In this project, scissor car jack is chose as the subject that its weight should be reduced so that at the same time it can reduce the burden of the car. Moreover, topology optimization technique is used to solve the weight reduction of scissor car jack. The material of the existing scissor car jack will not be change in order to reduce the weight of the scissor car jack in the aspect of topology optimization only. The scissor car jack is developed to 3D model before it can be optimized using the Altair Optistruct software. The design of the scissor car jack will be recommended from the software after the constraint and boundary conditions are set in the software. Linear static analysis is performed to study the deflection of the scissor car jack after a set of load is applied on the jack. In this project, the design constraints are displacement and stress while the objective function is volume fraction of the model. Lastly, the original weight of the scissor car jack is 2.5 kg and after it undergoes topology optimization, the weight of the new design is 2.22 kg where the weight of the original design is reduced around 11%.
