Abstract
With the five-axis grinding machine tool bed as the research object, the maximum deformation region can be found after analyzing the static characteristics in the use of the grinder limit positions. Through free modal analysis and constraint modal analysis, the vibration characteristics of each order of the bed can be seen and a point in the maximum deformation region is selected to carry out the harmonic response analysis to predict the sustainable dynamic characteristic. According to the results of analysis, find out the weak areas in the bed and conduct the weight-lowing optimization on the condition of no reduction of static and dynamic characteristic of the bed. This paper draws the conclusion of reduction of weight of 143.42kg and materials of 7.73%.
