摘要

针对现有液压支架抗冲击支护结构无法实现主动让位、让压等问题，在前期复合式抗冲击装置的研究基础上，对基于复合式抗冲击装置的新型防冲液压支架的抗冲击特性进行了深入研究，构建了新型防冲液压支架冲击动力学模型，探究了复合式抗冲击装置的最优安装位置，研究了不同载荷和不同电流条件下复合式抗冲击装置对液压支架抗冲击特性的影响。在理论研究的基础上，试制了产品样机并进行了试验验证。研究结果显示:复合式抗冲击装置可以有效降低冲击峰值力，当复合式抗冲击装置通0、1、2 A电流时，在1.1倍工作载荷的冲击力下，冲击峰值力分别降低了2.23%、1.68%、1.11%；在1.25倍工作载荷下的冲击力下，冲击峰值力分别降低了4.41%、3.22%、2.01%；在1.4倍工作载荷的冲击力下，冲击峰值力分别降低了7.62%、5.81%、3.23%。结合冲击动力学模型，研究了改进Bang-Bang控制与模糊PID（proportional-intergral-derivative）控制的半主动控制策略，建立了仿真模型，研究结果表明:复合式抗冲击装置可以实现主动让位与主动让压，并能够提升抗冲击装置的吸能量、减小立柱所受冲击的峰值力。

Abstract

Aiming at the problem that the existing anti-impact support structure of hydraulic support cannot achieve displacement and pressure release, based on the previous research of composite anti-impact resistance device, the anti-impact resistance characteristics of new anti-impact hydraulic support based on composite impact resistance device were studied in this paper. The impact dynamic model of the new anti-impact hydraulic support was constructed, and the optimal installation position of the composite anti-impact device was explored. The influence of the composite anti-impact device on the impact resistance of the hydraulic support under different loads and different currents was studied. Based on the theoretical research, the prototype of the product was trial-produced and verified by experiments. The results show that the anti-impact peak force can be effectively reduced by the composite anti-impact device. When the composite impact device is connected with 0 A, 1 A and 2 A currents, the impact peak force is reduced by 2.23%, 1.68% and 1.11%, respectively, under the impact force of 1.1 times the working load. Under the impact force of 1.25 times the working load, the peak impact force is reduced by 4.41%, 3.22% and 2.01%, respectively. Under the impact force of 1.4 times the working load, the impact peak force is reduced by 7.62%, 5.81% and 3.23%, respectively. Combined with the anti-impact dynamics model, the active control strategy of improved Bang-Bang control and fuzzy PID control is studied, and the simulation model is established. The results show that the composite anti-impact device can realize active displacement release and active pressure release, and the energy absorption of the anti-impact device can be improved and the peak force of the impact on the column can be reduced.
