Based on the modal analysis theory, the experimental modal analysis of the machine tool feed system was made by u?sing hammer?hitting method. Dynamic characteristics of the machine tool feed system were studied, and its natural frequencies, damper ratios and mode shape were also obtained. Through analysis of the mode shape of feed system at each stage, its structural weaker parts are found, and the suggestion of improvement is provided for the optimization design of structure.
