The finite element method (FEM) is a numerical method for solving problems of engineering and mathematical physics. Typical problem areas of interest include structural analysis, heat transfer, fluid ...
1. 油气润滑电主轴热行为复现：从热网络法到 Newton-Raphson 的温度分布预测 高速电主轴跑到 6000 rpm 以上，轴承外圈温度到底会爬到多少度、热变形会不会把预紧吃掉，这类问题在样机装配前很难靠经验拍脑袋。这份资源给了一套能直接跑的 Python 复现代码，把油气润滑下轴承热变形耦合进电主轴热 ...
