The light self weight, large flexibility, small damp and low natural vibration frequency make it very sensitive to wind load. 大跨空间结构自重轻、柔性大、阻尼小、自振频率低，对风荷载比较敏感，风荷载已经成为大跨空间结构设计的重要荷载。 - 2
The natural vibration frequency and type, the dynamic characteristics of damping is important, car, wind power calculation and analysis of the earthquake. 结构的固有振型、频率和阻尼是重要的动力特征，是车振、风振及地震分析等动力计算的基础。 - 3
Air spring is characteristic of variable stiffness, its natural vibration frequency is much lower than that of leaf spring and will not change with load of vehicle. 空气弹簧具有变刚度特性，其固有振动频率要比钢板弹簧低得多，且不随汽车承载质量的变化而改变。
