【摘要】：轴向柱塞泵振动产生后,会按照某种规律沿着一定路径向外传递。以斜盘式轴向柱塞泵为研究对象,分析其机械振动产生机理及传递规律,建立振动传递路径模型;以泵后壳体作为振动传递的最终受体,建立了泵机械振动向后壳体传递的路径模型;通过数值模拟和实验确定模型参数,利用MATLAB对数学模型进行求解,得到了机械振动向后壳体传递的规律;基于路径传递率的概念,对振动传递路径系统进行了路径贡献度分析,并辨识出主要传递路径;搭建了轴向柱塞泵振动测试实验台,进行了实验研究。结果表明:所建立的轴向柱塞泵振动传递路径模型和求解方法较为准确,分析误差小于5%。该研究方法为轴向柱塞泵振动传递、能量耗散规律研究,以及参数灵敏度分析奠定理论基础。
[Abstract]:After the axial piston pump vibrates, it will pass outward along a certain path according to some law.Taking oblique disc axial piston pump as the research object, the mechanism and law of mechanical vibration generation are analyzed, the vibration transfer path model is established, and the rear shell of pump is used as the final recipient of vibration transfer.The path model of the transfer of mechanical vibration to the back shell is established, the parameters of the model are determined by numerical simulation and experiment, the mathematical model is solved by MATLAB, and the law of the transfer of mechanical vibration to the back shell is obtained, which is based on the concept of path transfer rate.The path contribution degree of the vibration transfer path system is analyzed and the main transfer path is identified. The vibration test bench of axial piston pump is built and the experimental research is carried out.The results show that the vibration transfer path model and solving method of axial piston pump are more accurate and the analysis error is less than 5.The research method lays a theoretical foundation for vibration transfer, energy dissipation and parameter sensitivity analysis of axial piston pump.
