Analysis on Static Characteristic of HTC100 NC Lathe Bed
HTC 100 CNC lathe is a heavy machine tool. The lathe bed is the important part of the machine tool. The static characteristic of the lathe bed directly influence the machining accuracy and production efficiency of the machine tool. At present, the lathe bed design general depends on the designer’s experience. In this paper, the static analysis of the HTC100 CNC lathe bed is carried out with ANSYS 12.0. The node equivalent stress distribution cloud, the total deformation distribution of Lathe bed and the maximum distortion under various kinds of working conditions are obtained. According to the result, the structure of lathe bed design tends to conservative and the distribution of static stiffness is unreasonable, which is necessary to optimum design.
