Evaluation and Validation of an Air Spring Analytical Model
Year: 2003
Type: article
Abstract: The present paper responds to the following aim: to define a model, which can predict quite well the static characteristic of a bellow spring. In detail an analytical non-dimensional model of the bellow spring is obtained. It can describe the axial force and the effective area apart from its geometric size. The typical parameters of this model are spring geometrical ratio and number of convolutions. No detailed information about membrane characteristic is required. Internal volume and spring stiffness equations are then analytically derived.At last a dynamic model of the spring is developed using the static characteristics previously defined. This tool would be useful for particular applications that involve dynamics as a keyword, such as vibration isolators, vehicle suspensions and actuators.
