Selection Of

The selection of biomimetic prototypes mostly depends on the subjective observation of a designer. This research uses TRIZ to explore some inferential steps in bionic design of the heavy machine tool column. Conflict resolution theory of TRIZ is applied to describe improved and deteriorated parameters and a contradiction matrix is used to obtain recommended inventive principles. A reference table of solutions corresponding to the biological phenomenon and TRIZ solutions is formed to expedite retrieving the biomimetic object. Based on the table, herbaceous hollow stem is selected to imitate column structure. Four kinds of plant are chosen from the biological database. To select the best from four candidates, a bionic ideality evaluation index is proposed based on similarity analysis and ideality evaluation theory in TRIZ. Thus, the bionic effect can be described and compared quantitatively. Bionic configuration is then evolved concerning manufacturing requirements. Size optimization of stiffener thicknesses is implemented finally, and satisfactory results of the lightweight effect is obtained.

For application in large machine tools, the machined part quality, accuracy as well as machining speed depende greatly on the dynamics of the structure. In this paper, an active-excitation modal analysis (AEMA), using inertial force of the moving slider to excite the structural modes, is proposed. Modal parameters of the machine tool structure estimated by AEMA are experimentally validated. Since the artificial excitation produced by elaborate excitation equipment is replaced by the inertial force of the slider, the proposed method is much more practical and economical than traditional methods.

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.
