摘要:
研究4种规格液压管路的压接修理参数，并分析其在3种压力级别下的动力学特性变化规律。首先建立压接修理后液压管路的有限元模型，通过模态分析可知，当压接间隙为0 mm时，管路的各阶固有频率不随压接长度的改变发生明显变化，在0～1580 Hz频率范围内，随管路直径增大，管路所承受的最大范式应力值减小。因此，4种规格液压管路的压接间隙应为0 mm，压接长度根据飞机维修手册而定。在3种压力级别下对4种规格液压管路进行动力学特性分析，管路各阶固有频率均随压力增加而变大，最大变形量在3种压力级别下均小于5 mm，0.25 inch管路在35 MPa下的等效应力远大于21 MPa和28 MPa下的等效应力，且大于其余3种规格液压管路，管路等效应力最大的部位在压接接头处。
Abstract:The crimping repair parameters of four specifications of hydraulic pipelines were studied, and their dynamic characteristics under three pressure levels were analyzed. Firstly, the finite element model of the hydraulic pipeline after crimping repair was established. The modal analysis of the pipeline showed that when the crimping gap was 0 mm, the natural frequencies of each order of the pipeline did not change significantly with the crimping length. Within the frequency range of 0—1580 Hz, the maximum normal stress value withstood by the pipeline decreased with the increase of pipeline diameter. Therefore, the crimping clearance of the four specifications of hydraulic pipelines should be 0 mm, and the crimping length should be determined according to the aircraft maintenance manual. The dynamic characteristics of four specifications of hydraulic pipelines were analyzed under three pressure levels. The natural frequencies of each order of the pipeline increased with the increasing pressure. The maximum deformation was less than 5 mm under three pressure levels. The equivalent stress of 0.25 inch pipeline under 35 MPa was much greater than that under 21 MPa and 28 MPa, and greater than that of the other three specifications of hydraulic pipeline. The position with the maximum equivalent stress of the pipeline was at the crimping joint.
