摘要
测量了助力转向泵出口处的动态压力脉冲,结合对噪声的主观评价,对液压助力转向泵噪声进行了综合分析。通过对客观数据与主观评价结果的对比、关联分析,确定了有效、稳定的改进方案。
Based on the subjective assessment of noise, the noise of the hydraulic power steering pump is compre-hensively analyzed by measuring the dynamic pressure pulse at the outlet of the pump. Through comparison of the objective data and the subjective evaluation results, the method can assess the acoustic vibration better. It is helpful to determine the effective and steady improvement program.
