摘要
电液泵作为一种高集成度、高功率密度的新型液压能源,具有体积小、噪声低、振动小、散热好等优点,具有广阔的应用前景。针对电液泵在振动噪声方面的优势,以三相异步轴向柱塞式电液泵为研究对象,分析其机械振动的特点及传递规律,建立振动传递路径模型;以斜盘端盖、配流盘端盖及壳体作为振动传递的受体,确定影响振动传递的刚度、阻尼等参数,利用MATLAB对振动传递的数学模型进行求解,得到各振动受体在旋转体组件受激振力情况下的振动速度和加速度曲线。此研究可为振动传递系统路径贡献度分析提供支撑,对于电液泵振动性能的进一步提升奠定基础。
As a new type of hydraulic power source with high integration and high power density, the electric hydraulic pumps（EHP）have the advantages of small volume, low noise and vibration and good heat dissipation performance. As a result, EHP has broad application prospects. According to the advantages of low vibration and noise, the EHP integrated with a 3-phase asynchronous motor and an axial piston pump is analyzed for the characteristics of mechanical vibration and transmission. The model of the vibration transmission path is established. With the swash plate end cover, valve plate end cover and the shell as vibration receptors, the stiffness, damping and some other parameters that affect the vibration transmission are determined. The mathematical model of vibration transmission is solved by MATLAB, and curves of vibration speed and acceleration of each vibration receptor is obtained when the exciting force acts on the rotary component.This study may provide a support for the analysis of the path contribution of the vibration transmission system and lay a foundation for the further improvement of the vibration performance of EHP.
