Study on Energy Dissipation Characteristics of YGG Type Steel Wire Rope Shock Isolator Excited by Shock Loads
摘要
Abstract
In this paper, the model of YGG type steel wire rope shock-isolation system with single degree of freedom is introduced, and the energy response equations are derived.By solving the equations, the transfer, dissipation and distribution of the energy are obtained when the system is excited by shock loads.The principle of passive shock isolation of YGG type steel wire rope shock-isolation system is revealed from the viewpoint of energy.Based on the analysis of the results, the influence of input total energy, pre-compression, weight quota and axial force on the energy distribution and the energy dissipation characteristics of the steel wire rope shock-isolators is discussed.The axial and lateral energy-dissipation abilities of YGG-8kN steel wire rope shock-isolator are obtained.This work provides a reference for theoretical study on the entire shock isolation, efficiency evaluation, technique and design study in explosion and shock environment.关键词
