Annotation: Article considers approaches to improve the functioning of tensile strength testing machine K-1, based on modelling the mechanical and informational processes of its operation. The pendulum movement registration process is analysed in detail, resulting in a set of restrictions imposed on data processing methods used during simulation. Based on this, a set of recommendations is developed, regarding the correct way to track pendulum’s motion. It is suggested to register intervals between consecutive encoder pulses, rather than independently poll encoder’s current position using a timer. Based on this idea, a simulation algorithm is developed that allows for a close reproduction of the properties of the data gathered during experiment. This algorithm is implemented in a software system. The data produced by this system closely resembles the data gathered during experiments with a real device. As such, the model and the algorithm can be used to develop a quality control system for the K-1 machine.
