摘要：

The characteristics of air springs, such as the effects of bellows and those of heat transfer on spring constant and damping factor, have been studied. However, auxiliary chambers and pipes are required in addition to air springs, to vary spring constant in the case of spring rate change by electronically controlled air suspension systems of a vehicle. Few reports have dealt with the effects of auxiliary chambers and pipes. In our study, the relation between vibration frequency and spring reaction has been investigated to clarify the effects of pipes on dynamic spring constant. Our proposed model has proved effective in understanding the phenomena.
