Analysis And Experimental Study On Mechanical Properties Of Steel Wire Rope Vibration Isolator

As a new type of metal isolator based on dry friction damping mechanism, it is a hot issue that how to improve its vibration isolation performance. The performance of wire rope vibration isolator is closely related to the wire rope, and the different forms of wire and wire are different. However, due to the complex structure of steel wire, the stress is more complicated. Therefore, it is very difficult to analyze the performance of the vibration isolator. In this thesis, the vibration isolation device is studied by using the macro analysis to determine the stiffness and damping characteristics of the wire rope vibration isolator. Then the wire rope vibration isolator is simulated and the hysteresis loop is obtained. The results show that the wire rope vibration isolator has good performance of vibration isolation, especially suitable for special environment, which has broad application prospect.In this thesis, the static model of the wire rope vibration isolator is established, and the vibration isolation principle is analyzed and the characteristic curve of the hysteresis loop is obtained. Secondly, a variety of wire rope vibration vibration isolator is studied. The load-deformation curve and hysteresis loop of the model are obtained by static test. Provide experimental guidance for the design and research of wire rope vibration isolator. Finally, establish a finite element model of steel wire ring, stress strain analysis, to study the stiffness and damping characteristics.The results show that the mechanical characteristics and the theory of the static and dynamic experimental data of wire rope vibration isolator are consistent, and the simulation results are in line with the theoretical study. At the same time, the wire rope vibration isolator has the advantages of low rigidity, good damping performance, strong environmental adaptability and so on.
