description: The topic of the graduation qualifying work: "Mobile pulse testing stand". The graduation work is devoted to the design of a test bench for testing objects with pulses of high accelerations, as well as checking its main node for destructibility during testing. Tasks that were solved during the study:1. Analysis of the design and operation of the test bench. 2. Identification of the most loaded part of the test bench. 3. Modeling of the finite element grid. 4. Conducting a verification calculation based on the developed grid.The paper describes the essence of a numerical method for solving problems by modeling a finite element grid using ANSA and Ansys Workbench software. General representations and classification of numerical methods for solving problems are given. The reasons for using the finite element method to solve the problem are given based on the analysis of the literature devoted to the methods of calculating thick-walled shells.The operation of the pulse test bench was analyzed, and the purpose of its nodes was determined. A precision grid of finite elements has been developed for the main unit of the test stand - the body of the acceleration unit. An automatic simplified finite element grid has been developed for calculations at the first and second approximation, considering all the features of the geometry of the hole for the pressure sensor. Verification calculations were carried out based on the Ansys Workbench program. Technological recommendations for reducing destructive stresses around the stress concentrator have been developed.
