✦ Synopsis

The characteristics of air springs, such as the e!ects 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 e!ects of auxiliary chambers and pipes. In our study, the relation between vibration frequency and spring reaction has been investigated to clarify the e!ects of pipes on dynamic spring constant. Our proposed model has proved e!ective in understanding the phenomena.
