ANALYSIS OF PECULIARITIES OF DIESEL DAMPER CONTROL ON THE BASIS OF SPECIAL FLUID MODEL TESTING
The authors conducted comparative testing of torsional vibration dampers on a test bed with two kinds of fluid - polymethylsiloxane fluid (PMF) and magnetic fluid (MF). The test bed and tests conducted on torsional vibration were calculated and the boundaries for the research of resonance frequency were marked. For the research, the fluids PMF-1000 and MF-131 with kinematic viscosities of 1000 and 1100 cSt correspondingly were used. Data for reduction of resonance stress of torsional vibrations for both fluids were obtained. Using PMF-1000 resulted in the reduction of stress by 2.68 and 2.67 for MF-131. The behavior of both fluids is presented in graphs. Resonance frequency of vibrations for using PMF-1000 and MF-131 was 28.6 and 27.8 Hz correspondingly.
