| 摘 要： | 提高机床运动结构的比刚度对于提高机床加工精度以及系统动力学性能具有重要作用.基于结构仿生的原理和方法,在分析骨架对生物体刚度的贡献以及体现了最佳的载荷路径这一思想的基础上,对叶片抛磨机立柱内部的筋板结构进行重新设计,使其发挥骨架的作用.对原型及仿生型立柱进行了静力、模态及瞬态动力学分析,经过有限元分析发现,立柱的质量减小,比刚度结构效能得到了较大的提高,其静动力学性能也有明显的改善.

| Abstract: | Improving the specific stiffness of moving structure is important for the improvement of the machining accuracy and dynamic performance of high speed machine tools.Based on structural bionic theory,through study on the contribution of biologic skeleton to organism stiffness and the concept that biologic skeleton shows the best load path of organism,the column's inner structure was redesigned as skeleton to improve the specific stiffness.The static,modal,and transient analyses of original column and bionic c... |
