The Effect of Wire Rope Material on Vibration Characteristics
Hüseyin DAL, Murat BAKLACI
Wire rope vibration isolators (WRI) are used to protect particularly sensitive and high technology products from severe dynamic loads such as shock and vibration. WRI is widely used in many industries, especially in the defense and space industry. In this study, the effect of rope material used in WRIs on vibration characteristics was experimentally investigated. WRIs were fabricated using nuflex, stainless steel and galvanized steel ropes as the main material component of the rope. Design and fabrication of 3 identical WRI models each with a rope diameter of 3 mm, namely Nufleks (NWRI), stainless (SWRI) and galvanized steel rope vibration isolator (GWRI), were performed. The produced WRI models were subjected to tensile-compression tests under different speed and pre-load conditions and then, force-displacement responses were obtained. In addition, dynamic vibration tests of WRI models were performed using the shaker system and accelerometers. As a result of the studies, it was observed that the rope material used in the WRIs significantly affected the vibration characteristics. When the quasi-static test results are examined, it is clearly understood that GWRI exhibits a more rigid characteristic compared to other models. At the same time, when the damping ratios obtained from hysteretic cycles are compared, it is clearly seen SWRI has the highest damping ratio. When the dynamic tests performed by shaker are examined, it is clearly seen that the isolator with the best vibration isolation characteristics is SWRI.
