Study on Effect of Filter Cut-off Frequency on Rough Point Contact Mechanism
滤波截止频率对粗糙点接触机理影响研究

Influences of filter cut-off frequency,by which fine rough surface characteristics can be further achieved after obtaining rough surface roughness,on contact mechanism for rough point contact were investigated with authors contact program based on FFT technology and conjugate gradient method.Numerical results show that the cut-off frequency used for has a significant effect on curve of applied force against approach between the two contacting bodies.The smaller cut-off frequency,the larger contact area and ...
