Machine dynamics laboratory is directed to:
Laboratory exploits unique equipment Dynamical dynamometer to simulate loading regimes of dynamical systems (drive – transmission – technological unit and the unit Tribotestor M89 to determine the tribological characteristics of contact materials used in sliding joints subjected to broad scale of load intensity and various time history of loading. The laboratory includes the system PULSE (Bruel&Kjaer) with additional modules for FFT analysis, Envelope analysis, Order analysis and with module for time domain data acquisition. This system enables to provide noise and vibration analysis as well as measurement of modal and damping properties of materials. Noise measurements are accomplished using 2250 sound-level meter Bruel&Kjaer with additional modules for FFT and frequency analysis. System QuantumX MX840 (HBM) enables to perform measurement of applied loads, resulting deformations, deflections, rotations as well as general tensometric measurements.
Laboratory includes also analytical scales ABT100-5M and EG4200-2MN, two-channel oscilloscope HAMEG MH1507, impulse generator RIGOL DG1022, two electrodynamical vibration exciters with amplifiers, contact/noncontact tachometer DT2230, thermocamera Flir i7, surface roughness tester TR200 and tensometric station M2000.
Laboratory is used within collaboration with external firms: ŽOS Trnava a.s.; ZF SACHS Slovakia, a.s.; VUJE, a.s.; metal design slovakia a.s.
