The article presents the simulation analysis of the main elements of the restraint system. Such system provides a protection in case of accidental ejection of plug assembly during pressure testing of high-pressure valves. The aim of the analysis is to increase safety in the operating pressure tests at the manufacturer of valves facilities. The input data in form of qualification of the plug assembly ejection velocity in the event of the accident are taken from the article V. Horák, J. Komenda and L. Do Luc: Analysis of the Released Plug Assembly Motion published in this journal. This article presents the estimation of the limit thickness of three possible barrier materials which can be used in the construction of the restraint system elements. The analysis was performed using 2D Ansys Autodyn simulation model. Results of the analysis can be used as a basis for design of the restraint system capable to safely absorb the shock of flying body with the energy of tens to hundreds of thousands of joules.References
