Static Stress Analysis and Fatigue Life Prediction of Rocket Motor Test Stand Using Numerical Simulation

The rocket motor test stand is the equipment used to motor's performance under controlled conditions. This measure thrust of Dextrose and ability components such as tube, fuel, nozzle cap itself. Before flight carried out, it must go through this test. In study, variations in are 2000, 2250, 2500, 2750, 3000 N. stands Aluminum 6063-T6 which has light density medium strength. Numerical simulations were out with Ansys Workbench software using finite element method. results static stress analysis show that greater thrust, maximum von Mises deformation. It inversely related safety factor. lower factor stand. fatigue simulation prediction life Rocket fails reach a 1 million cycle at N thrust.
