More Information
Summary:The invention relates to the field of tire detection, and discloses a tire eccentric wear early warning method which comprises the following steps: step 1, acquiring tire temperature, tire pressure and acceleration data of a tire through an intelligent tire sensor; step 2, calculating a tire ideal harmonic spectrum f1 through tire design information; step 3, taking the obvious grounding characteristic of the sensor as a boundary of one-circle rotation of the tire; 4, performing Fourier series decomposition on the multi-period signal, and performing coherent averaging on a complex frequency spectrum to obtain a frequency spectrum f2; step 5, calculating a cross spectrum p1 of the frequency spectrum f2 and the frequency spectrum f1; 6, calculating the energy spectrum entropy of p1 to obtain e1; and 7, calculating the ratio of p1 to P, setting an alarm threshold value L, and giving an eccentric wear alarm when the ratio is greater than L. The early warning method for tire eccentric wear does not depend on high-s
