Open publisher page 0 citations

Abstract

Abstract:The dynamic characteristics of CY6140BT lathe were studied using the GLOBAL method. The damping rations and modal shapes of the main modal frequencies have been obtained. Correctness and reliability of the model were verified by comparative fitting results method. The results show that the working frequency fended off natural frequencies of the lathe. Which indicated that the lathe meets the design goals and work requirements.
