分形理论在减振器性能畸变判定中的应用

Application of Fractal Theory in Absorber Performance Distortion

针对减振器速度特性中力与速度信号的特点,从分形理论出发,利用分形维数的概念,建立求解分形维数的模型,对减振器实测信号进行定量描述。试验结果表明,减振器性能畸变出现时,其分形维数明显不同,因此,可以利用分形维数有效地判定减振器性能是否畸变。

According to the characteristics of force and velocity signals of shock absorber,based on fractal theory and the conception of fractal dimensions, the model for solution of fractal dimension is founded, it can describe quantitatively measured signals generated by shock absorber. Experiment results show that the fractal dimensions are different in the difference of performance distortion. The distortion pattern recognitions of shock absorber are effective and accurate.
