The effect of fluid properties on hydraulic cylinder rod seal stick‐slip friction was studied. Breakaway and stick‐slip forces were measured for three ISO VG 32 fluids with slipper, U‐cup, and Vee‐pack seals. Breakaway forces increased exponentially with dwell time. Stick‐slip friction produced audible low‐frequency noise. Differences in the stick‐slip behavior of the fluids were observed. Fast Fourier transform analysis of sound, force, and mechanical vibrations was conducted. Stick‐slip friction increased the amplitude of low‐frequency vibrations in all three domains. Micro stick‐slip movement was elucidated via motion amplification technology. These findings provide a basis for the development of fluids that improve the control and safety of hydraulic equipment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
