摘要
在行星传动系统工作过程中,由于行星轮的公转,行星轮与齿圈的啮合点不断发生变化,啮合振动信号因此受到传递路径的影响。在啮合点远离传感器端的过程中,其信号强度逐渐变小,在靠近传感器端的过程中,信号强度逐渐增大。为了准确描述该啮合振动信号传递路径的变化规律,利用Virtual.lab建立行星齿轮箱壳体有限元模型,通过Matlab曲线拟合工具箱建立传递路径变化规律的数学模型,为行星传动系统振动信号的数学建模提供理论支持。
In the working process of the planetary gear sets,the meshing points of planet gears and ring gear continually change due to the revolution of the planet gears,and the transfer path of meshing vibration signal is also affected. In the process of the meshing points,getting far away from the sensor,the signal strength decreases gradually,and in the process of the meshing points getting near the sensor,the signal intensity increases gradually. In order to accurately describe the changing law of meshing vibration signal transfer path,a finite element model of planetary gear box shell was built in Virtual. lab. And the mathematical model of transfer path changing rule was established through Matlab curve fitting toolbox,which provides theoretical support for the mathematical modeling of planetary gear sets.
