气囊在工程保障中的有限元简化模型研究

Study on the simplified finite element model of gasbag in engineering security

利用有限单元法,首次提出了与有限元网格划分相关的简化方法,并利用该方法对简化弹簧系数进行了探讨,研究了弹簧系数在不同的内压、倾角、直径下的变化,将复杂的气囊模型简化为常用的弹簧模型,从而简化了计算过程。

Using finite element method, it firstly proposes the simplified method associated with the finite element mesh, discusses the spring coefficient with this method, and then studies the changes of spring coefficient under different pressure, different angle, and different diameter, finally simplifies the complex gasbag into commonly used spring model. Thus, it simplifies the calculation process.
