采用“卸积木式”力学模型及以拟静力学模型建立的主轴轴承刚度矩阵对机床主轴系统的结构进行优化 ,通过数学变换较大地减少计算量 ;经过对多种机床主轴系统的分析计算 ,实现了体积和刚度的优化 .并以 M2 110 A型内圆磨床的磨头为例 ,验证了优化设计的效果
The structure of the spindle system of the machine tool is optimized by using the “unloading block” mechanical model and the spindle bearing rigidity matrix established by the quasi-static model. The mathematical transformation greatly reduces the calculation amount. After analyzing and calculating the spindle system of various machine tools, The optimization of the volume and the stiffness.And the grinding head of M2 110 A internal grinder is taken as an example to verify the effect of the optimization design
