摘要

根据高铁牵引齿轮箱特性,确定齿轮箱振动、噪声、应力测试的不同工况,并搭建试验台进行测试。箱体额定负载不变工况下,箱体的加速度幅值、空气噪声值和应力值,随转速的升高呈增大趋势。当转速值为2 500 r/min和3 500 r/min时,箱体的加速度幅值出现峰值。在额定转速和额定负载工况下,对箱体加速度和空气噪声值进行频域分析,结果表明箱体振动主要由啮合频率及其倍频引起,在啮合频率及其倍频旁存在边频带,边频间隔为输出轴转频、输入轴转频;箱体的最大空气噪声值为89.74 dB,出现在2 400 Hz附近,对应啮合频率2 391.7 Hz。试验结果可为箱体的理论分析提供试验数据。

Abstract

The experiment on vibration,acoustic noise and stress of gearbox housing in high-speed train under various work condition was determined and experimental test was carried out on test bench according to the characteristic of gearbox housing.The results revealed that amplitude of acceleration,value of air noise and stress increased with the rotating speed increased when rated load remained constant. The value of acceleration of gearbox reached the greatest when the rotating speed is 2 500 r/min or3 500 r/min. The vibration of gearbox housing was caused by engagement frequency and multiplication frequency according to the frequency domain analysis of acceleration and air noise under the rated rotating speed and load was constant,and there was sideband near to engagement frequency and multiplication frequency which frequency interval was the rotating frequency of the output shaft and input shaft. The maximum value of air noise is 89. 74 dB which occurred around the frequency of 2 400 Hz,it meets the engagement frequency of 2 391. 7 Hz. The experimental results can provide experimental data for the theoretical analysis of the gearbox housing.
