Vibrating characteristic analysis and model Simplification of air bag based on contact algorithm

为了对舰用气囊隔振器隔振特性进行评估,使用ABAQUS软件计算了不同安装方式的隔振器系统的前20阶固有频率,并在此基础上进行了频率响应分析,得出不同安装方式对隔振性能的影响。在总结精确有限元模型计算结果的基础上提出了囊式空气弹簧隔振器的简化有限元模型建立方法。分析计算的结果表明:通过有限元数值仿真计算能够全面地分析囊式空气弹簧隔振器的隔振特性。文中研究对于舰用囊式空气弹簧隔振器的隔振模型及设计有一定的参考价值。
