DESIGN ANALYSIS AND TOPOLOGY OPTIMIZATION FOR SCISSOR CAR JACK USING STATIC LINEAR APPROCH

Abstract

Vehicles are used for transporting people or goods, especially on land. Generally, vehicles come with jacks as standard tools in assisting people to change flat tyre. They tend to use this tool whenever tyre/s need to be changed in flat tyre condition or replacing worn tyre/s in the workshop. The aims of this project are to analyze different types of scissor car jacks for sedan model in Malaysia using Finite Element Analysis (FEA) software and propose a new design for upper and lower arm scissor car jack using topology optimization technique. The structural model of scissor car jack was developed using computer aided design (CAD) software. The analysis and optimization were performed using SOLID THINKING INSPIRE 2016 software by Altair. A linear static analysis was performed to study the deflection of scissor car jack. The results based on topology optimization technique indicate the original weight of scissor car jack is 2.1 kg. However, after undergoing topology optimization, weight of the new design is 1.4 kg which is reduced by 35% from the original design.
