基于弹性力学理论的隔爆壳体计算方法

In the underground complex work environment, the flameproof shell requires sufficient strength and stiffness to ensure that when an internal explosion happens, shell can withstand the impact of the explosion and prevent energy to spread to external to ignite the flammable gases in the environment. In order to find a simplified method for flameproof shell for accurate and reliable design and calculation, on the basis of analysis of explosion pressure conditions, proposed the use of small deflection theory of thin elastic to calculate the stress and strain of shell. Simplify the structure of flameproof shell, according the requirements of stiffness and strength to obtain the specific parameters of flameproof shell.
