Topological Optimization Design and Performance Analysis of BFPC Oblique bed CNC Lathe
摘要
Abstract
To improve the static and dynamic performance and lightness of a machine tool.This paper take a CNC lathe's oblique bed as the prototype preliminary design of a basalt fiber polymer concrete (BFPC) oblique bed and analyze the force of the oblique bed under typical working conditions.The static and dynamic characteristics of the two kinds of oblique bed are simulated and analyzed.Then,the optimization design of the BFPC oblique bed is carried out according to the topological optimization results and manufacturing processes of the BFPC oblique bed,whose structure is reconstructed.With the factor of its weight reduction pore size taken into consideration,the natural frequency of the first six modes are used as experimental indexes.Finally,experiments on single-factor rotation is conducted to determine the numerical value.The static and dynamic performance and lightness of the optimized BFPC bed are simulated and calculated and then compared with the prototype and optimized BFPC oblique beds before their corresponding performance is analyzed.The results show that the topologically optimized BFPC oblique bed is obviously better than the latter two in terms of static and dynamic performance and lightness.关键词
