| Abstract: | Based on the ordinary amounting construction of roller lead screw in NC machine tools, applying straight-bar fore-and-aft elastic brace simplifying model, this paper aims to simplify the fore-and-aft operating condition of roller lead screw in NC machine tools. Applying Laplace Transform and elastic vibration theory, the paper studies the modeling of fore-and-aft vibration conditions of roller lead screw on NC machine tools, the study then deducts the vibration functions and frequency characteristic equations of natural vibration on the conditions of various boundaries. An practical example proves the method and model to be simple and convenient, and feasible. |
