| Abstract: | Mechanical model of an airspring vibration isolator is studied.The calculation formula of its fundamental natural frequency is derived.The effect factors on its natural frequency are analyzed through practical examples.Results indicate that the fundamental natural frequency is affected by restricted angle,relative damping coefficient and volume ratio of the two chambers.The performance of the airspring vibration isolator could be improved by increase of restricted angle and volume of the chambers and decrease of relative damping coefficient. |
