The object of the research is the electromechanical test bench. The main purpose of the masters thesis is to study the rigidity of the test bench in order to take into account the deformations that occur during the operation of the bench, to process the test results and evaluate the effectiveness of ways to increase its rigidity. To solve the tasks set in the masters thesis, an analytical calculation of elastic deformations of the elements of the loading system of the stand and calculation by the finite element method were used. The calculations were carried out using software products: MatLab, MathCad and SolidWorks Simulation. Practical significance. The obtained research results can be used in the development and tuning of the test bench control system and the test results processing system. The results of the work can also be applied in the modernization of the test stand in order to increase its rigidity. Conclusions. As a result of the study, the stiffness function of the test bench was obtained, the influence of the parameters of the loading system on the rigidity of the bench during testing was analyzed, and recommendations were given to increase its rigidity. The scientific novelty of the study lies in the fact that the work for the first time considers the stiffness function of the loading system of the test bench in order to take into account its elastic deformations by the test results processing system.
