配流盘对轴向柱塞泵声振特性的影响

摘要

通过振动和噪声测试试验台,在两种不同的试验工况下,分别对轴向柱塞泵的表面振动速度和声压级进行了测试.使用傅里叶变换对测试数据进行处理,分析了不同试验工况下轴向柱塞泵的声振特性,探讨了振动速度和声压级之间的对应关系.然后对比了两种配流盘结构对声振特性的影响,给出了阻尼孔以及三角槽结构的配流盘的适用范围和各自的优势,为不同工况下轴向柱塞泵配流盘结构的选择提供了一定的参考.%The vibration velocity and the sound pressure level of the axial piston pump are measured under two different test conditions through vibration and noise test platform.The test data is processed by the Fourier transform,and the vibro-acoustic characteristic of the axial piston pump under different test conditions is analyzed and the correspondence between the vibration velocity and the sound pressure level is discussed.The impact of two kinds of valve plate structure on the vibro-acoustic characteristic is compared,and the scope and respective advantages of valve plate with damping hole or triangle groove are given,which provides a reference for the selection of the valve plate structure of the axial piston pump under different working conditions.
