摘要：The purpose of a car jack is lifting the car and maintaining it at a certain height during different repairs. Thispaper focuses on the design of car jack, which belongs to the basic equipment of cars. Cars jacks are used mainlyfor changing tires and small repairs of a car. The aim of this paper was to create a parametric CAD model of acar jack and carry out numerical structural analysis of the car jack using the created parametric CAD model. Thedevelopment of the parametric CAD model and structural analysis was performed using the CATIA V5 system.This paper describes the modern way of creating more complex mechanisms, which support quick modifcationof its parameters, and thus the entire design. The whole model of the car jack was parametrized. The stressesobtained by fnite element method (FEM) analysis were confrmed 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 wasperformed, on the basis of which specifed conclusions were made.
