The paper is aimed at the experimental testing of the impact energy of conveyor belts in terms of their resistance to puncture using the Design of Experiment (DOE) method. The plan of the experiment consists of selecting a response i.e., the analysed impact energy, defining selected factors: A ‒ impact height; B ‒ hammer weight; and C ‒ impactor type, designing and implementing the experiment, and evaluating the significance of the effects of the individual factors and their interactions using a t-test, which is expressed in the output by means of the p-value. The Pareto chart and the normal probability plot were used to evaluate the effects of the individual factors and their interactions on impact energy. The experiment was evaluated using a regression model by means of which the input and output variables were determined. The obtained regression model presents a complete three-factor experiment comprising the main factors and the interactions between them. The analysis showed that the three main factors A, B, C, and their first-order interactions AB and BC have a statistically significant effect on the response i.e., the output value of the impact energy.
