Maintenance on machines is a mandatory asset management activity to maintain asset reliability in order to reduce losses due to failure. 89% of defects have random failure mode, the proper maintenance method is predictive maintenance. Predictive maintenan... see more

The cavitation phenomena cause noise, vibration and instability in centrifugal pumps. Furthermore, the cavitation usually generates wear and material erosion of the rotor blades which decreases the hydraulic performance and the pump life. In this work, it... see more

A classifier plays a crucial role in the cement industry. It is in charge of separating coal that has been smoothened out and is ready to be burned although the coal is still rough after going through the grinding process. It takes a long time to burn coa... see more

A new scheme for the excitation of vibrations of the working bodies of the blocks of a vibration unit based on a change in the phase angles of unbalances between themselves is developed. The implementation of such an idea allows for one revolution of imba... see more

This work investigates aerodynamic elements’ vibrations of high-speed vehicles on the example of the Dallara T12 race car front wing. Made up energy spectrums of wing vibrations for three specific cases arising during driving on the circuit.

A main drive is an important mobilizing motor component in a raw mill. Due to the extremely condition of constant operation of the raw mill results in failure of the main drive. This disturbs the raw mix intake and halts the next processes. In order to ob... see more

When studying the temperature dependences of the acoustic absorption and the modulus of elasticity, absorption peaks are often observed, which correspond to the characteristic step on the temperature dependence of the modulus of elasticity. Such features ... see more

This paper deals with mechanical design and development of high speed digital board (HSDB) system which consists of printed circuit board (PCB) with all electronic components packaged inside the cavity for military application. The military environment po... see more
