    Diagnostics of buggy vehicle transmission gearbox technical state based on modal vibrations
    (JVE International Ltd, 2014) Shalapko, Yuriy; Łukasiewicz, Marcin; Kałaczyński, Tomasz; Musiał, Janusz
    This paper presents a diagnostics technique of beach buggy gearbox technical state based on the measurement of modal vibrations. It is well known that the vibration level of machine elements can be correlated to the technical state of the machine. The frequency analysis of vibration signals can be effectively used for the monitoring of the fault origination and development in rotating machinery. The proposed technique uses gearbox modal vibration data to identify and monitor developing faults in the buggy vehicle.

    Some surface layer features after abrasive-water jet cutting
    (2012) Matuszewski, Maciej; Musiał, Janusz; Styp-Rekowski, Michał; Shalapko, Yuriy; Mashovets, Natalia
    In presented paper results of comparative studies into the roughness (very significant tribological factor) of surfaces after cutting using the AWJM method were presented. Cutting was performed on samples made of three materials: quenched and tampered alloy steel (1.2080), plastic (polyamide PA6) and mineral material (syenite). Variable parameters in the cutting process included: jet pressure and feed. As a result of measurements involving selected roughness parameters (Ra, Rz and Rq)It was discovered that the majority of variable factors had a significant effect on the cut surface roughness. It was also demonstrated that the contact method measurements cannot be performed with regard to plastics because the results are characterised by a very great scatter of results values, making them unreliable.

    The vibrodiagnostics research of buggy vehicle transmission gearbox technical state
    (2013) Shalapko, Yuriy; Łukasiewicz, Marcin; Kałaczyński, Tomasz; Musiał, Janusz
    In this paperwere introduced of beach buggy chosen units and elements diagnostics researchresults with usage of vibroacoustics methods. Vibrations draw ahead in every mechanical object. The significant part of machines reliability is vibration level, which could be dangerous for machine technical state. Disturbance of balance state is the reason of vibration formation in machine parts. This vibration can exist and propagate even after their source expiration. Vibrations could be essential just after the crossing certain threshold marked by amplitude and the frequency of the phenomenon. They can be harmful for the object after crossing of this threshold of the vibration, or for his surroundings (e.g.: decrease of the durability of the material).
