Design of Elastic-damping Supports Made of MR Material for Pipeline Supports

Uncertain Frequency Responses of Clamp-Pipeline Systems Using an Interval-Based Method

“…V ij denotes the effect of interaction between X i and X j on V Y . The variance component V i is interpreted as the expected reduction of the total variance V Y obtained as a result of fixing X i , which derives the primary sensitivity coefficient of stiffness parameter X i as follows: (19) According to this definition, all sensitivity indices can be expressed, and added up to one:…”

“…Ai et al [16] utilized active control strategies to minimize the pressure-introduced resonance of the hydraulic pipeline. Besides, a variety of constitutive models of the clamp damping material were presented in previous literatures [17]- [19]. Zhang et al [18] established the relationship between the physical parameters (such as the damping factor and the Poisson's ratio of the clamp damping material) and the preparation parameters, and they found that the mechanical properties of nickel-based rubber can be controlled by adjusting the relative density during manufacturing.…”

Lazutkin et al [19] proposed a novel manufacturing technology to produce the new metal rubber that is more effective than traditional rubber in vibration reduction of pipelines.…”

Wearing of MR Wire Vibration Insulation Material Under Random Load

“…Its properties do not change during a very long time (dozens of years). Vibration insulators and elastic-damping supports made of MR are used widely for air and land transport [3,4]. Load on vibration protection systems for transport is random often.…”
