摘要

针对齿轮箱振动、噪声等共性关键问题，以某型地铁车辆转向架齿轮箱为研究对象，运用LMS Virtual Lab软件建立齿轮箱的刚柔耦合动力学和振动噪声仿真模型，对齿轮箱中斜齿轮副时变啮合刚度、支撑轴承动载荷、齿轮箱体振动、齿轮箱附近区域的结构噪声进行仿真分析，并对齿轮箱体振动和齿轮箱附近区域的结构噪声进行了试验验证。结果表明，地铁车辆转向架齿轮箱斜齿轮副时变啮合力、支撑轴承动载荷均呈现在某一均值上下周期性波动的趋势；齿轮箱体振动和齿轮箱附近区域的结构噪声在上下和左右方向上大于轴向方向上的；振动和结构噪声仿真值与试验值最大相对误差分别为14.61%和3.77%，验证了仿真分析的合理性和正确性。研究为地铁车辆及齿轮箱减振降噪提供了理论依据和技术支持。

Abstract

Aiming at the common key issues for gearbox vibration and noise

a certain type of subway car bogie gearbox has been regarded as the research object. The rigid-flexible coupling dynamics and vibration noise simulation model of the gearbox have been established by the LMS Virtual Lab software. The variable meshing stiffness

the dynamic bearing supporting load

the gearbox vibration

and the structural noise in the vicinity of the gearbox have been simulated and analyzed

and the vibration of the gearbox and the structural noise in the vicinity of the gearbox have been tested and verified. The results show that the time-varying meshing force of the helical gear pair of the subway car bogie gearbox and the dynamic load of the supporting bearing show a periodic fluctuation trend above and below a certain average value; the vibration of the gearbox body and the structural noise in the vicinity of the gearbox in the up and down

left and right direction are greater than those in the axial direction; the maximum relative errors between the simulated and experimental values of vibration and structural noise are respectively 14.61% and 3.77%

which can verify the rationality and correctness of the simulation analysis. The research provides a vibration and noise reduction for the theoretical basis and technical supporting of the subway vehicles and gearboxes.
