有限元模型建立质量的好坏,对求解规模和所得结果的准确性有很大影响。文中分析了单元划分、结构简化和焊点间距等对有限元模态分析结果的影响。
The quality of the finite element model is good or bad, which has great influence on the solution scale and the accuracy of the result obtained. The effects of element division, structure simplification and solder joint spacing on the results of modal analysis are analyzed.
