Abstract

Protection of sled systems from destructive vibrations is inevitably under attraction due to the importance of Sled Testing in the aerospace industry. A pair of SBR Dampers were used between the slipper and the sled body to reduce vertical vibrations, so a design of the sled model was studied. Both Equivalent Stiffness and Equivalent Damping of the sled system were obtained to reduce the transmission of vibrations from slippers to the body. A combination of analytical, numerical and experimental test methods was utilized and the results were validated. The stiffness values of 370500 and 391000 N⁄, m were obtained from numerical and experimental measurements, respectively. Finally, by designing the sled model, first and second natural frequencies of 12. 49 and 19. 56 Hz and mode shapes of the sled system were obtained. The results show that the Dampers used in the sled have an important role in reducing the transmission of vibrations to the sled body by withstanding the tension and pressure on the slippers.
