STUDY ON THE NATURAL VIBRATION CHARACTERISTICS OF SINGLE-POINT DIAMOND FLY CUTTING MACHINE TOOL BASED ON TRANSFER MATRIX METHOD FOR MULTIBODY SYSTEMS

摘要

Natural vibration characteristics play a very important role in the evaluation of the dynamics characteristics and the machined surface of a single-point diamond fly cutting machine tool (SDFCMT). In this paper, the natural vibration characteristics are studied from aspects of theory, computation, and experiment. By adopting the transfer matrix method for multibody systems (MSTMM), the dynamics model and its topology figure are established, and its natural vibration characteristics are computed. The computation results are verified by a modal test.
