    摘要:

    为提高立柱的抗冲击力学性能，设计了一种由接头、卡箍、吸能构件套、吸能构件和销钉构成的矿用立柱恒阻让位防冲装置，并根据立柱国标确定了防冲装置的承载力，给出了防冲装置工作原理及防冲原理。对常规立柱和安装防冲装置立柱在冲击载荷作用下的变形和受力进行了对比分析，得出在相同冲击载荷作用下，防冲立柱变形大大小于常规立柱变形，吸能防冲构件变形阶段能有效降低立柱承受的冲击力。防冲装置可方便安装于现有常规立柱上，防冲装置的使用大大增强了立柱的抗冲击性能。此恒阻让位防冲装置也可用于汽车、航空航天工业、高速公路安全防护等领域。

    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 anti-impact 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.
