摘要:
为增强液压立柱防冲性能，有效防治煤矿冲击地压，或在一定程度上减小冲击地压事故造成的损失，提出并设计了一种与液压立柱结合使用的内外翻转式吸能构件。采用数值分析对构件吸能防冲特性进行研究，结果表明：轴向压缩下内外翻转式吸能构件具有非常好的稳定变形破坏模式，且构件变形后不向四周膨胀。内外翻转式吸能构件压缩过程中具有恒定的反作用力、较高的冲程效率和有较小的载荷波动系数。内外翻转式吸能防冲构件是一种较为理想的吸能防冲构件，其与现有常规立柱结合使用，可改善立柱受冲击载荷时的受力情况，增强立柱防冲性能。
Abstract:
In order to enhance the anti-impact performance of hydraulic columns, prevent and control the rockburst in coal mine effectively, or to a certain extent, reduce the losses caused by rockburst accident, a kind of inside-outside overturning energy absorption components using combined with hydraulic column was put forward and designed. The energy absorption and anti-impact properties of components were studied by using the method of numerical analysis. The results showed that: the inside-outside overturning energy absorption component under axial pressure has an excellent stable deformation and failure mode. And the component will not expand to all around after deformation. The inside-outside overturning energy absorption component has a constant counterforce, a higher stroke efficiency and a smaller load fluctuation coefficient in the process of compression. The inside-outside overturning energy absorption anti-impact component is an ideal energy absorption and anti-impact component. The combination use of inside-outside overturning energy absorption and anti-impact component and conventional column can improve the force condition of columns under impact loading, and enhance the anti-impact performance of columns.
