A Scissor Jack is a mechanical device used to lift a heavy vehicle from the ground for changing the wheel and for maintenance purpose. The most important fact of a jack is that it gives the user a mechanical advantage by changing the rotational motion into linear motion and allowing user to lift a heavy car to the require height. In this work we have designed different components of scissors jack using CAE tools i.e. CATIA andCalculate stresses induced in its different part which are responsible for failure and To Reduce its cost so that everyone can afford this. We have taken reference of Mahindra Bolero Scissors Jack. The Dimensions of scissors jack was measured by Vernier caliper. By measuring all the dimensions of components of scissors jack we have designed it in CATIA after that we assemble all the components of Jack to shape a model of scissors jack and calculated different parameters Max. shear stress Max. principal Tensile Stress Total torque required to lift the vehicle etc which is used in all components of scissors jack to avoid failure. To reduce the cost of jack we have taken two different sections of three different materials i.e. Mild Steel AISI 1045 grade Steel GS-52.3 Cast Steel and comparing which will be suited for above mentioned purpose. By using these materials we have calculate and compare the Strength to weight ratio and find which material is best suited for high load carrying capacity with minimum failure or deformation.
