ABSTRACT
With the existence of the first car, there was a need for car jack. The purpose of car jack is lifting the car and maintaining the same at a certain height during different repairs. This paper will focus on the design of car jack, which belongs to the basic equipment of cars. Cars jacks are used mainly for changing of tires and small repairs of a car. The aim of this paper is to create parametric CAD model of car jack and carry out numerical structural analysis of the car jack using created parametric CAD model. The development of parametric CAD model and structural analysis is done using the CATIA V5 system. This paper describes the modern way of creating more complex mechanisms, which supports quick modification of its parameters, and thus the entire design. The whole model of the car jack is parametrized. Stresses obtained by finite element method (FEM) analysis are confirmed with the analytical calculation in characteristic parts of the design, with some exceptions. At the end of the paper an analysis of the obtained results was performed, on the basis of which specified conclusions have been made.
