Abstract

A jack is a mechanical device used as a lifting device to lift heavy loads or apply great forces. Jacks employ a screw thread or hydraulic cylinder to apply very high linear forces. The most common car jack used is screw car jack. The significance purpose of car jack modification is due to health risks especially back ache problems associated with doing work in a bent or squatting position during changing tyres process for a long period of time. With high-end technologies, an automatic car jack should be produced to help reduce body fatigue that lead to health problems. Conceptual automatic car jack can be developed by using total design approach where Pugh’s method is fully applied. This product development integrate with market need, product specification, concept design and detail design comply with each other. In this project, final conceptual design of car jack has been developed using total design approach. The result of FEA analysis shows the upper part of the car jack is in safety region. From these analyses, Von Mises Stress, Strain, Stress and Displacement detail of the car jack is determined.
