To reduce the lathe-bed and assure its stiffness requirement, a batten wall pore structure is designed.
为了减轻床身的重量和保证床身的刚度要求，设计了板壁孔结构。
Analyzed from the stress angle, the lathe-bed is mainly imposed by a vertically upward force, moreover, the lathe-bed is not slender, so the direction of tangential stress should not be ignored.
从床身的受力角度看来，床身主要受到垂直方向上的力，而且床身不是细长的结构，切应力的方向不能忽略。
This paper builds the three degree model based on drawing paper of this lathe-bed, using the solid building modular component in PRO/E.
本文依据图纸在三维建模软件PRO/E中，利用零件造型模块建立床身的三维模型。
The paper introduced how to build FEA model by the use of Pro/Engineer, and how to analyze the inhering frequency, quivering model and other dynamic Characteristics of lathe-bed in the Application of Ansys.
介绍利用Pro/Engineer建立有限元模型并通过Ansys分析床身固有频率、振型及动态特性。
