Abstract: This paper presents the analysis and experimental investigation of a bellow separation system of a launch vehicle. Transient analysis of the bellow separation system is carried out by non-linear dynamic implicit analysis using Abaqus 2019. Transient analysis revealed that the response of the separation system for both test and flight configuration is different. Test setup configuration is modified, and linear & non-linear transient analysis was carried out for the revised configuration. It has given enough confidence to proceed with the qualification program. Structural response of the system under separation event was captured using strain gauges. The test results are in good agreement with the finite element analysis results. It is noted that Non-linear dynamic implicit analysis gives better strain prediction for separation system transients.
Keywords: Launch vehicle, bellow separation system, transient analysis, strain measurement.
