description: The final qualification work is devoted to the development of a test shock stand for multiple impacts based on the prototype SMU600 in order to obtain certain charac-teristics of the shock pulse, confirmed by mathematical calculations. The analysis of the classification and the element base of the shock stands is carried out. The analogues of the test shock stands of manufacturers, which are world leaders in the production of test equipment, are considered. The structural-functional, kinematic and pneumatic-kinematic schemes of the developed stand are synthesized. Based on a mathematical model, the velocity before impact, reproduced by the developed impact stand, is estimated. The speed was estimated for the case of using a stand without a pneumatic accelerator and with a pneumatic accelerator in the form of a pneumatic spring for different operating pressures of the pneumatic system. An assessment of the shock pulse parameters that can be obtained on the developed wall has been carried out. Various geometric shapes of the impact table have been studied in the SolidWorks CAD software package. Based on the prototype, a 3D model of the stand has been developed. A model of a long-duration shock pulse shaper is proposed, and the possibility of changing the stiffness is provided.
