矿用立柱恒阻让位防冲装置的设计及其特性分析
Design of constant resistance giving way and anti-impact device of mining column and its characteristic analysis
摘要
Abstract
In order to improve the anti-impact mechanical properties of column,a kind of constant resistance giving way and anti-impact device of mining column is designed.The device is composed of a joint,clamp,energy absorption component cover,energy absorption component and pin.According to the Chinese standard of column,the bearing capacity of anti-impact device is determined,and the working and antiimpact principle of the device is given out.The contrastive analysis is conducted to study the deformation and stress of conventional column and the column installing anti-impact device under impact loading.The results show that under the same impact loading,the deformation of anti-impact column is far less than that of conventional column.The energy absorption and anti-impact component can effectively reduce the impact force on column in the deformation stage.The anti-impact device can greatly enhance the anti-impact properties of column,and it can be easily installed on the existing conventional column.And the constant resistance giving way and anti-impact device can be used in the automotive,aerospace industry,highway safety protection and other fields.关键词
