液压S形软管长度计算研究

Research on Length Calculation of Hydraulic S-Type Hose

摘要: 在大型液压系统中，软管作为活动和振动部位的柔性连接件，是管路中不可或缺的一部分。本文结合钻机液压管路装配的实际工程需求，对软管S形弯曲的长度规律进行了理论分析，并根据软管长度规律完成装配。规律表明，在S形管路中，预留的长度处于两种形态的长度范围内时，可以避免软管弯曲小于最小弯曲半径。研究结果有助于想在实际工程中精准计算软管长度范围以防止因为长度误差导致软管寿命降低、增加装配应力等情况。

Abstract: This article proposes a long calculation law for the length of the hose S-shaped shape to solve the calculation of the length of the hose connection between any two oil ports in the case of high pres-sure and large flow in the project. Combining the actual engineering needs of the drilling machine hydraulic tube road assembly, the length range is calculated according to the law of multiple and the hoses at the same time between different oil ports, and the assembly is completed. The assem-bly results show that when the reserved length is within the length range of the two forms in the S-shaped tube road, it can prevent the hose from being bent less than the minimum bending radius while meeting the assembly requirements. The conclusion of the research helps to accurately cal-culate the length of the hydraulic hose in actual engineering to avoid decreased hose life, increased assembly stress, and unable to complete assembly due to the length error.
