Experimental Studies on Three-Dimensional Performances of Vibration Isolator for Steel Wire Rope

Experimental investigation is made on three-dimensional performances of three types of vibration isolators for steel wire rope. The three-dimensional stiffness and damping affected by the diameter ratios D/d of the isolator, and the lengthwise and crosswise performances influenced by various radial loads are studied. The results show that the isolator possesses three-dimensional nonlinear softened stiffness and hysteresis damping behaviors and can be simplified to a model with bilinear hysteretic loop with a damping ratio above 0. 2.
