ABSTRACT. A jaw crusher is one of the most important machines in the field of hard material crushing and is used in the processing industry. This paper presents the possibility of modelling a real jaw crusher as a virtual model. The objective is to test a machine without time-consuming and costly experiments using real prototypes. Instead, simulations with a virtual prototype can predict the machine’s behaviour. A multi-body simulation is particularly suitable for simulating machines with moving components. The method of multibody simulation is analysed in relation to the development process and operation of a pendulum jaw crusher. With the model depicted in the simulation environment, studies on the design of a jaw crusher are conducted. The results are compared with values from empirical and analytical calculations. It is possible to analyse the kinematics and forces at any point on the crusher with the created model. Selected scenarios, such as the retraction mechanism and the stroke, were analysed.
Key words: jaw crusher, multibody simulation, digitalisation
