Investigation of the Durability of the Regulating Junction of the Christmas Tree Throttle

Objective: In the research work, the issue of ensuring the stability of its details wasconsidered by studying the voltage distribution mode in the throttle control node. SolidWorks software was used to perform force analysis of the improved throttle. Theoretical Framework: The research draws upon theories and simulations related to regulatory constructions and wear prevention. Methodology: In the research work, the performance criteria of the improved throttle have been studied. The force analysis of the proposed throttle's regulating node was carried out using modern methods and Solidworks simulations. Results and Discussion: The analysis of the wear occurring at the tip of the improved throttle shows that the wear resistance of this equipment is ensured, and the wear of the saddle-cutter pair, which has a hardness of HRC=55-66, amounts to 0.040...0.050 mm after 500 forward-backward cycles intended for the throttle. This is also twice smaller than the allowable limit. The processing of the conducted force analyses has proven that the performance of the improved throttle is ensured. Research Implications: The structural force analysis of the improved throttle shows that its performance is ensured. An analytical expression has been obtained to determine the maximum value of the radial stresses occurring at the tip of the throttle. It has been found that the safety factor for bending stress in the central zone of the throttle tip is equal to 2.5. Originality/Value: Based on simulations and analytical calculations, the radial stresses generated at the tip of the nozzle were investigated, and the longevity of the improved nozzle was enhanced based on new approaches.
