Abstract: The present invention relates to the technical field of bionic covert underwater acoustic communication, and specifically relates to a feature extraction-based imitated marine mammal sound signal covertness scoring method. The scoring method combines feature engineering to extract six universal features of a marine mammal sound signal from the perspective of human hearing and a signal waveform, and uses these features to obtain a second bionic signal covertness score through a weight coefficient formula. The covertness scoring method can characterize intrinsic information of the bionic signal in more detail from more perspectives of the signal to more accurately evaluate a difference between the bionic signal and a real signal, and the obtained score value can more intuitively describe the quality of the bionic signal covertness.

Abstract: A method and system for inversion of tire material parameters for wheel performance simulation. Based on a plurality of sets of test data obtained through tire radial rigidity and lateral rigidity tests, a tire radial rigidity and lateral rigidity test finite element simulation model is established, and error calculation is performed by comparing simulation results; and then the tire material parameters are optimized by optimizing a platform and combining results of error analysis, and a simulation process is circulated until the error is minimal, which is fitting of a test curve and a simulation curve. By using a neural network model, rapid inversion of the tire material parameters may be realized by using the neural network model only through non-destructive tire rigidity test data. The tire material parameters may be modified according to a large deformation process of a tire in a 90-degree impact test of a wheel.
