ARTICLE ANNOTATION

quote
The purpose of this work is to modernize the metal structure of the body of a dynamometer car for special technical purposes using modern modeling tools. To determine the loading of the structural elements of the dynamometer car, a calculated three-dimensional model of the car body was developed in the SolidWorks 2021 software package. With the use of the Ansys Workbench 2021 engineering program and the application of the finite element method, theoretical studies were carried out and the reinforcement points of the car frame were determined. The program and methodology of static tests for the strength of the body of a prototype dynamometer car model 61-907-DM for the railways of the Republic of Uzbekistan have been developed. The results of static tests for compressive/tensile strength of the car performed on the stand for loading the frames of cars and elements of coupling devices are presented. The stress-strain state of the car structure is determined when statically applied longitudinal test loads are applied to it.
