ME-497 Capstone Design project: Design and Analysis of Automated Pneumatic Jack System deploying Vehicle Exahust Power

Amid the increasing awareness on environmental impact and volatility of fossil fuel dependence, the research on the recovery of waste automotive power and exhaust energies technologies has enticed globally.

To date, various innovative designs and pilot demonstrations have gained significant thrust in the automobile industry. Conventionally car trailers use a mechanical feature to allow the human to raise the vehicle by manual force, by using the screw thread power or hydraulic jack which uses manual or hydraulic power.

These traditional Jack systems are either costly or require substantial laborious physical efforts. This research presents and examines the development of the car jack for emergency use using internal waste heat energy recovery.

The automatic easy carjack utilizes this power source to save individuals having to exert any energy which is suitable for elderly and disabled people.  To evaluate the design, a systematic morphological analysis was carried out to understand and ensure the efficacy of power, safety factors, and force (weight)sustainment. The Pneumatic Jack was developed utilizing the Solid works® which provides a detailed analysis of system integrity. The behavior of airbags was numerically validated viz Von Mises stress, Strain, and Deformation in two directions. Furthermore, final touches of optimization for preliminary design were madeby engineering analysis with ANSYS software. Finally, the fabrication strategy is envisaged to manufacture the carjacker most economically but to have enough power to lift and hold the car as a normal carjacking assembly.
