Damage Analysis of High Energy Density Capacitor Overload Explosion in Warship Cabin
By establishing the equivalent model of the overload explosion energy of the capacitor unit,the fluid-solid coupling process between the shock wave and the structure was solved by using the ar-bitrary Lagrangian-Euler(ALE)method,and the damage to the whole capacitor group caused by the explosion of the capacitor unit with different spacing and different positions was simulated.The dam-age results of capacitor banks under different working conditions were analyzed,and it was found that increasing the spacing of capacitor units can effectively reduce the damage degree of capacitor banks as a whole.When the capacitor unit explodes at the same position,the damage to the capacitor unit in front and right side is different with different spacing:when the spacing is increased to 2 times,the maximum displacement of the capacitor unit in front is reduced by 32.17％,and the maximum dis-placement of the capacitor unit in right side is reduced by 24.19％.When the spacing is increased to 3 times,the maximum displacement of the front capacitor unit is reduced by 48.69％,and the maximum displacement of the front capacitor unit is reduced by 41.13％.
