| Abstract: | Reasons of non-uniform microfeed of barometric pressure semi-suspension circular-ways are analyzed. The method of equivalent conversion is proposed for studying the characteristics of air-fow in complicated and irregular air-passage which is for med by the roughnees of ways-pair . The regularity of air-fow velocity is described by speed-tetrahedroid . The quantitative relation between design parameters of circular-ways and friction self-excited vibration is established, and the calculating example is giren. |
