摘要
利用受力结构仿生的原理和方法，对某型号电火花加工机床的关键运动部件---水平滑枕的内部筋板结构进行设计分析，在保证其结构刚度的同时，最大限度地进行轻量化。通过对叶片中叶脉结构分布规律的分析、总结，结合平滑枕部件的受力结构，设计出合理的筋板布局形式。应用SolidWorks建立结构仿真实体模型，并运用ANSYS有限元分析软件进行静力学分析和模态分析验证。研究结果对于保证机床相关运动部件的比刚度、提高机床工作精度以及系统动力学性能具有重要作用。
Abstract
By using bionic principles and methods of force structure,the internal rib structure of the key moving parts-horizontal ram of some EDM machine were designed and analyzed to ensure its structural rigidity,at the same time to make the maximum light-weight. Through the analysis of the distribution pattern of leaf veins structure,combining with the force structure of the smooth pillow member,reasonable layout form of the ribs was designed. By applying SolidWorks,the simulation structure of the entity model was es-tablished,and ANSYS finite element analysis (FEA)software was used for static analysis validation and modal analysis. The research results have an important role to ensure specific stiffness of the machine’s related moving parts,to improve accuracy and the system dy-namics performance.
