【 摘 要 】

The behaviour of materials was investigated using finite element modelling software (SOLIDWORKS and COMSOL).Three types of materials were studied: (1) ceramic (diamond), (2) metallic (titanium), and (3) composite (consisting of ceramicand metallic phases). Finite element modelling allows illustrating deformation and stressing the distribution of the test materialduring a single impact of the tribodevice with or without abrasive particles. The impact energy absorption was investigated. Realcomposite materials were produced by a combination of 3D printing (selective laser melting) of the lattice structure (Ti6Al4V)followed by addition of a hard ceramic phase with the help of the spark plasma sintering technique. The produced samples weretested by a laboratory impact-abrasive tribodevice. The results of modelling and laboratory testing were compared. The effectof modelling variables is illustrated. It is explained why composite materials showed better performance in impact-abrasiveconditions and are suitable for tunnelling and mining applications.
