Zusammenfassung:The invention provides a capacitance value numerical simulation solving method of a multilayer ceramic capacitor in an impact environment. The method comprises the following steps: constructing a three-dimensional entity model of the MLCC; performing mesh generation on the three-dimensional solid model, and constructing a finite element model; carrying out impact simulation analysis on the finite element model by utilizing LS-DYNA to obtain a deformation cloud picture of the MLCC; and extracting board spacing data in the deformed cloud picture, and obtaining the total capacitance value of the MLCC. According to the invention, the impact on the capacitor is simulated through a numerical simulation method, and the capacitance values of the MLCC in different impact environments can be obtained under the condition that no experiment is carried out. 本发明提供了一种多层陶瓷电容在冲击环境下容值数值模拟求解方法,包括:构建MLCC的三维实体模型;对所述三维实体模型进行网格划分,构建有限元模型;利用LS-DYNA对所述有限元模型进行冲击仿真分析,获取所述MLCC的变形云图;提取所述变形云图中板间距数据,获取所述MLCC的总电容值。本发明通过数值模拟方法模拟电容受到冲击,可以在不进行
