Description

This paper describes the design of a portable rocket rack and static stress analysis using numerical simulation. The portable rocket rack frame is designed to be able to carry 5 rockets. In this study, the load of each rocket was varied 150 kg, 175 kg, 200 kg, and 225 kg. The frame material for the portable rocket rack uses Aluminum 6061-T6. Numerical simulations were carried out with the help of Autodesk Inventor Professional software. The results of the static stress analysis show that the maximum von Mises stress for portable rocket racks for variations in loads of 150 kg, 175 kg, 200 kg and 225 kg, respectively, is 96.41 MPa, 112.5 MPa, 128.54 MPa, and 144.6 MPa. The portable rocket rack can withstand dynamic loads for each rocket of 200 kg because it has a safety factor of more than 2.
