摘要: 介绍了液压凿岩机的结构。结合非线性岩石模型,将凿岩机钻进岩石的过程,建立四自由度力学和数学模型。研究了粘滞和非粘滞模式,解释了这两种运动类型之间的差异。将液压作用力的角频率、振幅和垂直偏移量作为控制参数,进行了单参数延拓分析,发现了倍周期分岔、鞍结分岔和环面分岔。介绍了液压凿岩机钻凿岩石的数据采集系统,比较了模型和实验测得的液压作用力、活塞位移和活塞速度。结果表明,为了使凿岩机工作在周期-1轨迹,应该选择角频率的范围为2.09 < ω < 5.327,振幅的范围为0.012 < a < 0.746和0.005 < a < 1,垂直偏移量的范围为0.093 < b < 0.25。实验和模型的液压作用力具有相同的运行趋势,模型的活塞位移和速度大致位于“实验均值±标准差”的范围内,模型较好地模拟了实验结果。

Abstract: This paper introduces the structure of a hydraulic drifter. Integrated with a nonlinear rock model, the process of drilling the rock is established as a four-degree-of-freedom mechanical model and a mathematical model. Both stick and non-stick modes are studied, explaining the differences between these two types of motion. Taking the angular frequency, amplitude and vertical offset of the hydraulic force as control parameters, the single-parameter continuation analysis is carried out, and the period-doubling bifurcation, saddle-node bifurcation and torus bifurcation are found. A comparison is made between the piston displacement and velocity data obtained from the model and experimental results. The results indicate that to make the drifter work on the period-1 trajectory, the range of angular frequency should be 2.09 < ω < 5.327. The range of amplitude should be 0.012 < a < 0.746, 0.005 < a < 1. The range of vertical offset should be 0.093 < b < 0.25. The hydraulic forces of the experiment and the model have the same performance trend, and the piston displacement and velocity of the model are roughly within the range of "experimental mean ±standard deviation", which indicates that the model well simulates the experimental results.

Key words: hydraulic drifter, nonlinear rock model, continuation, stick, bifurcation
