摘要
从复杂机床底座的结构模型出发,对底座4种不同程度简化模型在分析过程中的合理性作了比较和探讨。得出同类复杂结构的模型简化规则,为建立合理的复杂有限元模型提供参考依据。
The structural models of the complicated machine bedframe were discussed, then compared the four different simplify structural models in rationality during the analysis process. And provide referrences for founding the highly precision of complicated FEA model reasonable after gotting the simplify rules of the complex structure as the machine bedframe
