摘要
针对爆胎识别这一问题,采用小波多分辨率分析技术,设计了一种爆胎识别新方案。通过模拟爆胎试验发现,该方案对爆胎时流通截面积以及不同的轮胎压力不敏感,能够准确判断爆胎发生。该方案的技术优势得益于小波分析技术无需事先对数据进行建模的特点,能准确寻找信号突变点,使得所设计的爆胎识别方案具有较强的适应能力。
In order to find a method to identify tire burst effectively, a new tire burst detection method using wavelet multi-resolution analysis was proposed in this paper. It is founded from simulated tire burst test that this method is not sensitive to flow area and different tire pressure when tire burst occurs, therefore it can accurately detect tire burst. Technological advantages of this method benefit from the features that wavelet analysis technique needs no modeling data in advance, therefore it can accurately find signal change point, and improve adaptability of the designed tire burst identification method.
