Abstract

The article addresses the issue of increasing the diagnostic capabilities of the car's suspension in the EUSAMA test. A new, quantitative approach was proposed to enable the assessment of the degree of wear and clearance of the lower suspension mount. An active diagnostic experiment was performed to model the clearance in the lower suspension mounting. During the research, bolts with different diameters were used. In the signal analysis, wavelet decomposition into 12 levels was performed using the Db4 wavelet. The resonance area of the system was extracted from an approximate signal, which contained 43.5% of the relative energy. From these signals, a number of point vibration measures were calculated. Finally, the maximum value was selected due to its sensitivity to the condition, which was 48% more than the original EUSAMA results. Based on the selected diagnostic parameter, a clearance model allowing for an assessment of the clearance with statistically significant coefficients was developed.

振动信号的多分辨率分析小波分解在汽车悬架状态监测中的应用

这篇文章探讨了在 EUSAMA 测试中提高汽车悬架诊断能力的问题。文章提出了一种新的定量方法，用于评估下悬架悬置的磨损程度和间隙。为模拟下悬架安装的间隙，进行了一次主动诊断实验。在研究过程中，使用了不同直径的螺栓。在信号分析中，使用 Db4 小波将信号分解为 12 个级别。从包含 43.5% 相对能量的近似信号中提取了系统的共振区。从这些信号中计算出若干点振动测量值。最后，选择了最大值，因为该值对工况的灵敏度比最初的 EUSAMA 结果高出 48%。根据所选的诊断参数，开发了一个间隙模型，可以评估具有统计意义系数的间隙。
