摘要

气囊隔振器作为一种高效的减振元件,其横向稳定性与横向刚度密切相关。为了在理论上了解和掌握长圆形囊式气囊隔振器的横、纵向刚度特性,分别根据气囊隔振器横、纵向受力特点,从气囊隔振器囊体受力和导向法兰受力两个方面对其横、纵向刚度进行了讨论,提出了一种长圆形囊式气囊隔振器横、纵向刚度理论计算式。同时试制相应气囊隔振器样机,并开展了长圆形囊式气囊横、纵向刚度特性试验,结果表明:理论与试验结果误差不超过3%,验证了所述方法的有效性,并且可以认定囊体提供的刚度占气囊横、纵向刚度的主要部分。

Abstract

As an effective vibration absorber,the lateral stability of the airbag isolator is closely related to the lateral stiffness.In order to understand and grasp theoretically the transverse and longitudinal stiffness characteristics of the long round bellow-type airbag isolator,according to the lateral and longitudinal force characteristics of the airbag isolator,the transverse and longitudinal stiffness of the airbag isolator from the bladder and the bearing flange were discussed.The theoretical calculation formula of the transverse and longitudinal stiffness of the airbag isolator was put forward.At the same time,the prototype of the corresponding air bag isolator was produced,the lateral and longitudinal stiffness characteristics of the long round airbag were tested.The results show that the error between theory and test results does not exceed 3%,which verifies the effectiveness of the method.And it can be determined that the stiffness provided by the capsule accounts for the main part of the lateral and longitudinal stiffness of the airbag.
