摘　　要：参考C_(60)分子和鸡蛋模型,构建了原始模型、C_(60)内嵌结构主轴箱模型、C_(60)空腔结构主轴箱模型和蛋壳仿生主轴箱模型等四种主轴箱模型.对原始模型、空腔模型和蛋壳主轴箱模型进行了模态分析和谐响应分析,得到了滑枕在不同位置时的固有频率和刚度;并用MATLAB对结果进行函数拟合和曲面拟合,比较模型的动刚度,得出了C_(60)空腔结构主轴箱模型是优良主轴箱模型的结论.With referencing the principle of egg and C_(60),the four main shaft box models were established,the structure of the C_(60) embedded model,C_(60) cavity structure model and eggs bionic model.The modal analysis and harmonic response analysis of model was analyzed.It is concluded that natural frequency and stiffness changs with the ram in a different position;by MATLAB,the function interpolation and the surface fitting were obtained of analysis result.By comparing the dynamic stiffness of the model,it is concluded that C_(60) cavity structure of spindle box model is a good structure of spindle box model.
